  • Reference Section of the Campanian Stage of the Southwestern Crimea:
           Problems of Substage Subdivision and Global Correlation

    • Free pre-print version: Loading...

      Abstract: — Stratigraphy of Campanian deposits in the stratotype of the Kudrinskaya Formation in the Southwestern Crimea is revised. For the first time, integrated sedimentological, biostratigraphic (ichnofossils, cephalopods, inoceramids, foraminifers, dinocysts, nannoplankton, gilianelles), isotope-geochemical, paleo- and petromagnetic characteristics of the section were obtained. The boundary of the lower and upper Campanian is substantiated and confirmed by U–Pb dating of zircons from the well-known bentonite (kil) clay bed in the interval of 77–80 Ma. It is proposed to accept the Campanian Substage boundary of the General Stratigraphic Chart (for bipartite stage subdivision) at the top of the Chron C33r, located near the δ13C isotopic excursion “MCaE” – Mid-Campanian Event, near the first occurrence of the benthic foraminifer Brotzenella monterelensis and a number of other traditional biomarkers.

  • Justification of the Age of Sands with Middle and Late Quaternary
           Theriofaunal Complexes in the Lower Ob River near the Village of Khashgort
           (Northwestern Siberia)

    • Free pre-print version: Loading...

      Abstract: For more than half a century, the question remained unresolved why the closely located sequences of fluvial sands overlying Middle Pleistocene diamicton in the lower reaches of the Ob River near the village of Khashgort contain micromammal faunas of different evolutionary levels: Late Quaternary (430 km from the Ob River mouth) and Middle Quaternary (442 (440) km from the Ob River mouth). This was in contradiction with generally accepted ideas, according to which the absence of Middle Quaternary alluvium was assumed in this area and called into question either geological or paleontological interpretations of the Pleistocene history of north of Western Siberia. This paper presents the results of correlating two geological sections based on both geological and paleontological methods and suggests an updated biostratigraphic interpretation of the materials relevant to the Karginian and Tazovian horizons of Western Siberia collected in the 1980s and 2016–2022. It was established that the Late Quaternary assemblage of micromammals from the sections at kilometer 430 of the Ob River is confined to alluvium of the second terrace above the river floodplain, while the Middle Quaternary assemblage at kilometer 442 (the Khashgort locality, kilometer 440 of the Bolshaya Ob River) is associated with fluvioglacial sands showing signs of close redeposition of small mammal remains in the megaclasts contained in Middle Quaternary Khashgort boulder-bearing sandy aleuropelites. Thus, the study makes it possible to harmonize the geological and paleontological data that were in conflict for more than half a century.

  • Subfossil Spore–Pollen Spectra of Northern Yakutia as a Key to the
           Interpretation of Paleoecological Studies

    • Free pre-print version: Loading...

      Abstract: The results of the study obtained for spores and pollen from the subfossil spectra of samples from the Bykovsky Peninsula (northern Yakutia) are presented in order to compare them with the current vegetation composition, to consider the major cryogenic disturbances of palynological remains, and to analyze their cryogenic destruction processes. The abundant alien pollen of Betula sect. Nanae and Alnus in the spectra is due to open landscapes, relatively low pollen productivity, and the transition of herbs and shrubs prevailing in the local phytocenoses to a vegetative propagation in severe climatic conditions. The selective role of cryogenesis in the spore–pollen spectra formation is related to repeated sediment thawing and freezing cycles, resulting in physical damage (ruptures and cracks) in palynological remains. The results of research contribute to the study of the methodological aspects of palynotaphonomy in cryolithic zone sediments. They can be used to reconstruct the Neopleistocene landscapes and vegetation and to study cryopreservation of fossil living organisms and their diversity in the permafrost areas.

      Abstract: The lithogeochemical peculiarities (content and distribution of main rock-forming oxides, as well as some trace elements) of clayey rocks of the Volynian, Redkinian, Kotlinian, and Lower Cambrian stratigraphic levels of the west of the East European Plate (Belarus and Volyn, east of the Baltic Monocline, and Moscow Syneclise) are analyzed. Using various lithogeochemical approaches and methods and data on U–Pb isotopic age of detrital zircon populations, which occur in sandstones associated with mudstones, and taking into account geochemical peculiarities of possible source rocks of fine-grained alumosiliciclastic material (igneous associations of different composition and age of Sarmatia and Fennoscandia), we provided ideas on a possible contribution of the latter associations to the formation of the Vendian and Early Cambrian clayey rocks.

  • Microfauna, Palynomorphs, and Biostratigraphy of the Upper Bajocian
           Strenoceras niortense Zone (Middle Jurassic) of the Kuban River Basin,
           Northern Caucasus

    • Free pre-print version: Loading...

      Abstract: Microfossils of the Strenoceras niortense Zone of the Upper Bajocian of the Karachay-Cherkessian Republic are studied. The zone is represented mainly by dark gray silty-sandy clays, with scattered nodules often arranged in interbeds, and belongs to the lower part of the upper subformation of the Djangura Formation. The taxonomic composition and distribution of foraminifera, ostracods, dinoflagellate cysts, and miospores in the section has been identified. The ranges of biostratigraphic units based on foraminifera, ostracods, and dinocysts are emended and these units are correlated with the ammonite scale. The distribution of benthic foraminifers indicates that these are Beds with Ophthalmidium caucasicum, comparable with the entire Niortense Zone and most of the Garantiana Zone. The Beds with Globuligerina dagestanica established using planktonic foraminifera are correlated with the entire studied interval from the Niortense Zone to the Lower Bathonian, inclusive. In the middle-upper part of the Niortense Zone (Rostovtsevi and Baculatum Subzones), the Beds with ostracods Palaeocytheridea (Malzevia) subtilis were recognized for the first time. The beds with dinocysts Carpathodinium predae, Rhynchodiniopsis' regalis, Meiourogonyaulax valensii are correlated with the range of the Niortense and Garantiana Zones and the lower part of the Parkinsoni Zone, inclusive. Characteristic taxa of microfauna and dinocysts are illustrated.

  • Biodiversity of Himgir Sub-Basin, India during Late Permian: A
           Comprehensive Study

    • Free pre-print version: Loading...

      Abstract: The Himgir sub-basin is the southwestern part of the Ib River Basin, Odisha, India. A Lower Gondwana fossil horizon was explored along the road section near Himgir Village, Sundargarh District, Odisha and plant megafossils (1002 specimens) comprising both pteridophytes and gymnosperms, four plant groups, ten genera and fifty-five species were reported. Pteridophytes (Equisetales, Sphenophyllales and Filicales) are represented by Schizoneura gondwanensis Feistmantel, 1876, equisetaceous stems, Trizygia speciosa Royle, 1839 and Neomariopteris talchirensis Maithy, 1974. Gymnosperms are represented by one plant group namely Glossopteridales (46 species Glossopteris) along with stem casts, fructifications and scale leaves. The occurrence of Late Permian floras, the lack of distinctive Dicroidium flora of the Triassic period in this assemblage, and the red bed facies (ferruginous red sandstone and ferruginous red shale) of the investigated locality reveal that the exposure belongs to Lower Kamthi Formation of Wuchiapingian to Changhsingian age. The macrofloral assemblage demonstrates a warm-humid climate with flashing rainfall and moderate light intensity. Vegetation of the studied sub-basin has also been studied to portray the palaeobiodiversity of the area.

  • Stratigraphy and Depositional History of the Middle–Upper Jurassic
           Platform Carbonate Succession in Kıraç Mountain (Western Central
           Taurides, S Turkey)

    • Free pre-print version: Loading...

      Abstract: This study covers a detailed stratigraphy, microfacies analysis and depositional history of the Middle–Upper Jurassic succession in the central part of the Taurides Carbonate Platform (TCP), southern Turkey (Kıraç Mountain, west of Central Taurides). The succession is subdivided into four units (Unit-1–Unit-4) and nine microfacies (MF1–MF9) are distinguished. Based on microfacies three depositional facies belts are determined and the depositional history of the platform part is explained. The Aalenian is represented by occasionally sandy, oolitic limestones (Unit-1), which indicate predominantly high-energy platform edge environmental conditions (shoal facies belt). The Bajocian–Kimmeridgian'/Tithonian' is represented by limestones with occasionally interlayered dolomite–dolomitic limestones (Unit-2–Unit-3), which are dominated by inner platform conditions (lagoon facies belt). During the Late Jurassic (Кimmeridgian'/Tithonian')–Early Cretaceous (Berriasian) a significant environmental change occurred, recording a rapidly occurring platform drowning event. This period is represented by dolomite–dolomitic limestone–limestone (Unit-4) containing interlayers of ammonite, radiolarite, laminated limestone, mudstone, and limestone blocks that indicate an open shelf environment (open-marine facies belt). The Middle–Upper Jurassic carbonate succession in Kıraç Mountain has characteristics similar to other parts of the Taurides Carbonate Platform. However, it differs in that it contains Unit-4 characterizing the open shelf environment in the latest Jurassic–earliest Cretaceous.

  • Polymetamorphism in the Geological Development of the South Altai
           Metamorphic Belt, Central Asian Foldbelt

    • Free pre-print version: Loading...

      Abstract: The crystalline complexes of the Hercynian South Altai Metamorphic Belt (SAMB), which is a part of the Central Asian Foldbelt more than 1500 km long. They compose different-scale tectonic plates, the level of metamorphism in which at the early stages reached the conditions of high-temperature amphibolite subfacies and, in places, granulite facies. In terms of tectonics, the band of their outcrops is confined to the margin of the North Asian Caledonian continent, stretching from southeast to northwest along the southern slope of the Gobi, Mongolian, and Chinese Altai to Eastern Kazakhstan, where they are represented in the Irtysh shear zone. The SAMB includes poly- and monometamorphic complexes. The age of granitoids formed at the late episode of metamorphism was determined for the Tsel tectonic plate of the Gobi Altai in the southeastern part of the SAMB: from 374 ± 2 to 360 ± 5 Ma. These and previously obtained results show that the early stage of low-pressure metamorphism and the late stage of high-pressure metamorphism occurred in the age intervals of ~390–385 and 375–360 Ma, respectively, almost throughout this belt. A short-term stage of stabilization was between these stages. These processes occurred during the closure of the basin with the Tethys-type oceanic crust of the South Mongolian Ocean (paleo-Tethys I). The spatial position of the SAMB is determined by the asymmetric structure of the basin, in which the active continental margin is represented along its northern part, and the passive one is represented along the southern one (in modern coordinates).

  • Bio-Magnetostratigraphy of the Turonian–Coniacian Deposits of the Lower
           Bannovka Section, South-East of the Russian Plate

    • Free pre-print version: Loading...

      Abstract: The lithological, paleontological and biostratigraphic characteristics of the Turonian–Coniacian deposits of the Lower Bannovka section, the stratotype of the Bannovka Formation (Volga region, Turonian) are presented. Magnetostratigraphic characteristics of thе sediments have been supplemented and elaborated. Petromagnetic data contribute to more refined stratigraphy of the section and facilitate the revealing of depositional rhythmicity. Paleomagnetic data combined with benthic foraminifera data enable the most detailed correlation of the Turonian–Coniacian deposits in the Volga region. Results of a comprehensive study of this stratigraphic unit within the southeastern arch of the Ulyanovsk-Saratov trough revealed patterns in the distribution of the Gubkino Horizon, determined by regional tectonics and processes preceding deposition in the Coniacian and Santonian.

           Art, Problems and Prospects for Improvement

    • Free pre-print version: Loading...

      Abstract: This paper discusses the current state of knowledge of Paleogene stratigraphy of Kaliningrad Oblast, the age of local stratigraphic units and the duration of possible gaps in deposition and proposes trends for future regional Paleogene stratigraphy. The Paleocene Chistoozerskaya and Lubava formations in total probably correspond to the Danian–Selandian on the basis of foraminiferal zonation, but their relationship is not entirely clear. The Zaostrovskaya Formation probably corresponds to the upper Thanetian, but its fossil record is very poor. The Sambian Formation corresponds to the Ypresian according to foraminifera, but its precise stratigraphical interval remains insufficiently substantiated. The Alka Formation is presumably late Lutetian–early Bartonian. The age of the Prussian Formation is emended based on dinocysts as early–late Priabonian, while the Palvé Formation is now dated as the latest Priabonian. The Kurshskaya Formation corresponds to the uppermost Eocene–Oligocene–'lower Miocene. The problem of the recognition and duration of hiatuses between formations remains relevant.

    • Free pre-print version: Loading...

      Abstract: — New data on the taxonomic composition and stratigraphic distribution of benthic and planktonic foraminifera in the Campanian–Maastrichtian interval of the Beshkosh section (Southwestern Crimea) are presented. Samples were collected using the “sample-to-sample” method for different types of analysis. Zones and Beds were established on the basis the foraminiferal succession. The Angulogavelinella gracilis LC 18 Zone, Bolivinoides draco LC 21 Zone, Brotzenella praeacuta LC 22 Zone and Beds with Gavelinella sahlstroemi were recognized using benthic foraminifera and Beds with Laeviheterohelix glabrans, Guembelitria cretacea Zone were recognized using planktonic foraminifera. All recognized biostrata are correlated with magnetostratigraphic, palynomorph and macrofauna events. Beds and zones recognized based on benthic foraminifera are correlated with Campanian–Maastrichtian bioevents in sections of the European paleobiogeographic region. Planktonic foraminiferal data are correlated with the International Stratigraphic Scale (Tethys Region) and the regional stratigraphic scheme of Poland. For the first time, 15 species of nine planktonic foraminifera genera and 38 species (25 of which were found for the first time) of 25 benthic foraminifera genera have been identified in the Beshkosh section.

           European Platform: U–Pb Age and Petrology

    • Free pre-print version: Loading...

      Abstract: On the basis of the mineralogical-petrographic and geochemical study of igneous rocks of intermediate composition of the Pripyat complex of the Late Devonian Pripyat–Dnieper magmatism area, two subphases of the Pripyat magmatism phase have been distinguished: late Fransian (Chernin or Skolodino–Chernin) with potassium specification and early Famennian (Turov–Drozdov (Yelets)) with potassium-sodium specification. For the first time, the U–Pb age of titanite from trachyandesites of the parametric Pribor borehole was estimated for rocks of Pripyat–Dnieper magmatism area at 364 ± 1 Ma. These data confirm the Famennian age of the Yelets subphase of the Pripyat phase of magmatism and make it possible to estimate the duration of the magmatic activity of this structure at least 14 m.y. taking into account the isotope dating of the earliest phases of magmatism in the Pripyat–Dnieper–Donetsk Paleorift Structure as 388 ± 12, 383.3 ± 3.8, 384.7 ± 3.9, and 383.6 ± 4.4 Ma in the Azov Region and 381 ± 2 Ma in the Pripyat–Dnieper magmatism area.

  • The First Detrital Zircon Data on the Northwestern Precambrian Yenisei
           Ridge: Identification of the Continental–Arc Kiselikha Terrane

    • Free pre-print version: Loading...

      Abstract: — Northwestern segment of the Precambrian Yenisei Ridge contains ophiolite and is known in literature as the Isakovka Terrane or Isakovka domain. We suggest to divide it into two belts: Kiselikha (western) and Torzhikha (eastern), which differed in geodynamic regime during the Late Neoproterozoic (750–600 Ma). It is believed that the Kiselikha belt is mostly composed of volcanic rocks erupted at island arc setting in the second half of the Neoproterozoic, and that collision of this arc with the Siberian Continent formed the Yenisei Ridge orogen. This idea has not been sufficiently supported by geological and geochronological data. Dating of four detrital zircons samples extracted from sedimentary and volcanic-sedimentary rocks in the southern part of the belt revealed that the sampled strata belong to three different Precambrian levels: the Mesoproterozoic, the mid-Neoproterozoic (800–750 Ma), and the end of the Neoproterozoic (620–600 Ma). Thus the authorized stratigraphic layout of the belt, as well as its proposed island-arc origin requires revision. By this paper we announce the identification of the Kiselikha Terrane , which was a part of active margin of the Siberian Paleocontinent at the beginning of the Neoproterozoic. Approximately in the middle of the Neoproterozoic, this block was rifted off Siberia and further evolved as a microcontinent bounded by an active margin from the outer side.

  • Late Pliocene Gilbert Type Delta and Early Pleistocene Drainage System
           Changes in the Erzurum Basin, NE Turkiye

    • Free pre-print version: Loading...

      Abstract: The Late Pliocene Gilbert-type delta is described in the western Erzurum Basin (NE Turkiye) and its position in the Late Cenozoic development of the basin is defined. The Erzurum Basin originated no later than Late Miocene between two Mesozoic ophiolite zones, continuing the Izmir–Ankara–Erzincan suture. In the Late Miocene–Pliocene, the basin was filled with fine-grained clastic and carbonate sediments of lacustrine-lagoon type. The Gilbert-type delta formed at the top of these deposits in the western part of the basin. The delta consists of 11 wedge-shaped bodies of clay, silt, sand, and gravel that were deposited as foresets of different phases of the delta development. The foreset bodies are dipping at 5° to 35° E. Some bodies underwent soft sediment deformation. The delta deposits are dated to Late Pliocene based on remains of small mammals and molluscs, palynological, and magneto-stratigraphic analysis. The delta eroded surface is overlain by alluvial pebbles dated to Early Pleistocene by archaeological finds. The Erzurum Basin is the westernmost member in a row of intermontane basins that continues to the east with the Pasinler, Horasan, and Agri basins that are drained by the Araxes River and its tributaries. It is likely that the paleo-Araxes River spread to the west in Late Pliocene and the studied delta was formed by its upper reaches that flowed into the water body of the Erzurum Basin. The delta deposits were covered by coarse alluvium in Early Pleistocene when the Erzurum Basin was tectonically isolated from the Araxes drainage system. In the latest Early Pleistocene or early Middle Pleistocene, the paleo-Araxes upper reaches were captured by the Euphrates River upper reaches that drain the Erzurum Basin now. The Upper Miocene and Pliocene deposits of the Erzurum, Pasinler, and Horasan Basins are similar and were accumulated in a single basin of sedimentation. Therefore, it can be assumed that the deposits of the upper Pliocene, containing the Akchagylian marine biota in the Horasan Basin, extended into the Erzurum Basin. However, the assumption that the upper reaches of the Euphrates River and the Erzurum Basin were the channel, through which the open sea biota entered the Akchagylian basin, is very unlikely for two reasons. Firstly, the Erzurum basin was limited by the described delta of the river, which flowed into it from the west.

  • Progress in Comparison of Elephantidae Fauna Based on Dental Study between
           the Plio-Pleistocene of the South of Eastern Europe and the Upper Siwaliks
           of India

    • Free pre-print version: Loading...

      Abstract: Plio-Pleistocene faunal complexes of the south of Eastern Europe and the formations of Upper Siwaliks of India were correlated. Proboscidean assemblages were used as a biomarker to revise evolutionary levels, first appearance, and migration patterns between the two regions. Four faunal complexes in the south of Eastern Europe and two interval-zones in the Upper Siwaliks of India have led to the framework for the first Plio-Pleistocene biostratigraphic correlation of these two regions. The work was based on two first appearances and six local and regional peak appearance events for Elephantidae. The first appearance datum of Elephantidae in Eurasia occurred during the Late Pliocene. During the Early Pleistocene, both regions show local evolution of different elephantid species, leading to a boom in their overall numbers. Evolving dental features such as total plate number, enamel thickness, lamellar frequency, hypsodonty index, etc. for last molars M3/m3 of Archidiskodon specimens from the south of Eastern Europe and Elephas specimens from the Upper Siwaliks of India were measured and compared. Dental features of Palaeoloxodon, a common genus occurring in both regions, were also compared. The morphometric results showed a faster and more consistent rate of evolution for the Elephantidae lineage from the south of Eastern Europe. The present study, along with a literature review of stratigraphic data, suggests a diachronous appearance of Elephantidae with the Indian record predating that in the south of Eastern Europe.

  • The Age and Depositional Settings of the Upper Paleogene–Lower Neogene
           Kurshskaya Formation in its Stratotype Section (Kaliningrad Oblast) based
           on Palynological Data

    • Free pre-print version: Loading...

      Abstract: — The results of the palynological study of the Kurshskaya Formation stratotype (Primorsky quarry, Kaliningrad Oblast) are presented. The lower part of the Kurshskaya Formation (Member of “chocolate” clays) contains an assemblage of latest Eocene dinoflagellate cysts Areosphaeridium diktyoplokum, Glaphyrocysta semitecta, and Cordosphaeridium funiculatum. The formation is characterized by four spore-pollen assemblages: (1) latest Eocene Pinuspollenites–Inaperturopollenites–Sciadopityspollenites assemblage in the “chocolate” clays and in the lower part of brown sands; (2) early Oligocene Sequoiapollenites–Betulaepollenites betuloides assemblage in the lower part of the brown sands member; (3) early Oligocene Boehlensipollis hohli–Carpinipites carpinoides in the middle part of brown sands member; (4) late Oligocene–early Miocene Alnipollenites–Corylopollis assemblage in the upper part of the brown sands of the Kurshskaya Formation. In total, the Kurshskaya Formation is terminal Eocene–early Miocene in age. The lower part of the Zamland Formation, which overlies the Kurshskaya Formation, contains the presumably middle Miocene Pinuspollenites–Tricolporopollenites pseudocingulum–T. euphorii assemblage. Based on the obtained palynological data, the depositional settings at the end of the Eocene–Oligocene–early Miocene in the South Baltic region are reconstructed. The regression of the marine basin began as early as the end of the Priabonian, the climate was still quite warm and humid, close to subtropical. Mesophytic mixed coniferous-broad-leaved forests grew along the shores of the strait, lowlands were occupied by marsh vegetation. Cooling at the Eocene/Oligocene boundary resulted in the appearance of hemlock in plant communities and increase in the proportion of catkins (alder, birch, hornbeam). Presumably, in the late Oligocene–early Miocene, the proportion of small-leaved trees, especially alder and hazel, sharply increased in mesophytic forests, while the number of pine trees decreased. Wetter and warmer climatic conditions are assumed for the early Miocene: this time is characterized by an increase in the number of walnut, cypress, and Cyrillaceae. In the middle Miocene, the climate was still quite warm, but drier, and such moisture-loving species as Podocarpus, spruce, Glyptostrobus, and swamp cypress disappeared from plant communities.

  • Stratigraphic Significance of Larger Benthic Foraminifera in Miocene
           Carbonates from Nam Con Son Basin, Vietnam

    • Free pre-print version: Loading...

      Abstract: Larger benthic foraminifera (LBF) in Southeast Asia developed prosperously in the Neogene. So, they play a meaningful role in defining the stratigraphy and depositional environment of carbonate formations. Many studies from a lot of localities in this region have been published to present their prevalence, diversity and their significance. However, they remain poorly published in Vietnam even though they are recorded abundantly in the Miocene carbonate deposits in the Tertiary basins on the Vietnam continental shelf, especially in the Nam Con Son Basin, in the southeast. This paper presents the first review on LBF in Miocene carbonate sediments and their stratigraphic range in the Nam Con Son Basin. As a result, a stratigraphic framework for the Miocene LBF of the basin, ranging from Te5 to Tg letter stages, is established. This may be used to identify the geological age and to support the correlation of carbonate deposits in this area. In general, their evolution demonstrates the development of carbonate formations in the basin, which are connected to the opening of the South China Sea; foraminifers follow the main evolutionary lineages of the Indo-Pacific province but have distinctive characteristics. In the Early Miocene, LBF appeared sparsely in Te5, then became frequent in lower Tf1. In the Middle Miocene, they presented their diversity and abundance in the fauna of Miogypsina, Lepidocyclina (Nephrolepidina), Cycloclypeus and Katacycloclypeus. In the Late Miocene, some of them were recorded in the carbonate formations in the high structures in the southeast of the basin.

  • Structure and Depositional Environment of the Upper Cenozoic Ulan-Zhalga
           Reference Section, Western Transbaikalia

    • Free pre-print version: Loading...

      Abstract: The results of a comprehensive study of the Upper Cenozoic Ulan-Zhalga reference section in western Transbaikalia are presented. The paleontological, paleomagnetic and petromagnetic, lithological-mineralogical, and geochemical data obtained allowed us to identify and characterize the Lower, Middle, and Upper Pleistocene and Holocene deposits in the section and to reveal the features and conditions of sedimentation. Five members recognized in the section are combined into two sequences: the lower (Beds 1–27, units 1–3) and the upper (Beds 28–35, units 4–5). The boundary between Matuyama and Brunhes chrons (0.773 Ma) is determined at a depth of 15 m and the upper boundary of the Jaramillo subchron (0.990 Ma) is determined at a depth of 23 m. The Matuyama/Brunhes boundary coincides with the boundary of Lower and Middle Pleistocene faunal assemblages. The formation of the section corresponds to two major stages of sedimentation with the boundary between the units 3 and 4 (depth of 11.8 m). Changes in rock magnetic and grain size parameters through the section has a climatic nature and reflects environmental changes. The formation of the lower part of the section (unit 1), which was accompanied by active soil formation, is characterized by the most heat- and moisture-enriched conditions. The upper sequence of the section accumulated under colder and drier conditions with increased dynamics of aeolian processes.

  • Reference Sections, Fossil Ichthyofauna and Sr Isotope Signature of the
           Lower Frasnian Sediments of the Latvian Saddle and Orsha Depression,
           Belarus

    • Free pre-print version: Loading...

      Abstract: — Lithology of the Lower Frasnian (Upper Devonian) sections, including the Zhelon Regional Stage and the Saria Beds of the Sargaevo Regional Stage, exposed in the basin of the Saryanka River, the Latvian Saddle, is described. The complete lithological description of the Sargaevo and Semiluki deposits (Frasnian) in the Gralevo quarry of the Vitebsk Region, Orsha Depression is presented. Photographic images of macro- and micro-dimensional remains of heterostracans, placoderms, acanthodians, sarcopterygians, actinopterygians, as well as scolecodonts and conodonts found in the Lower Frasnian deposits are presented. For the first time, the Sr isotope composition was measured in remains of ichthyofauna from the Zhelon and Sargaevo deposits of Belarus. Paleoichthyological and taphonomic data, lithology and Sr isotope composition of ichthyofauna fragments, depositional environments in the Zhelon and Saria times were clarified, and the distant sections were correlated. The 87Sr/86Sr values in ichthyofauna samples from the Saria Beds in sections of the Latvian Saddle (sections of Kalyuty 5a and 6, Virenka 1) and the Orsha Depression (Gralevo quarry) lie within similar ranges: 0.70825–0.70842 and 0.70837–0.70856, respectively. The 87Sr/86Sr values in ichthyofauna from the Zhelon deposits in the Kalyuty 2 and Obukhovo 1 sections (Latvian Saddle) vary within 0.70898–0.70932 and 0.71065–0.71102, respectively. High 87Sr/86Sr values in the fossil ichthyofauna of both regional stages suggest that the Early Frasnian paleobasin was significantly desalinated, while the salinity in the Saria paleobasin was comparable to the salinity of the modern Baltic Sea.
