Geodynamic controls on clastic-dominated base metal deposits
- Abstract: Geodynamic controls on clastic-dominated base metal deposits
  Anne C. Glerum, Sascha Brune, Joseph M. Magnall, Philipp Weis, and Sarah A. Gleeson
  Solid Earth, 15, 921–944, https://doi.org/10.5194/se-15-921-2024, 2024
  High-value zinc–lead deposits formed in sedimentary basins created when tectonic plates rifted apart. We use computer simulations of rifting and the associated sediment erosion and deposition to understand why they formed in some basins but not in others. Basins that contain a metal source, faults that focus fluids, and rocks that can host deposits occurred in both narrow and wide rifts for ≤ 3 Myr. The largest and the most deposits form in narrow margins of narrow asymmetric rifts.

Naturally fractured reservoir characterisation in heterogeneous
sandstones: insight for uranium in situ recovery (Imouraren, Niger)
- Abstract: Naturally fractured reservoir characterisation in heterogeneous sandstones: insight for uranium in situ recovery (Imouraren, Niger)
  Maxime Jamet, Gregory Ballas, Roger Soliva, Olivier Gerbeaud, Thierry Lefebvre, Christine Leredde, and Didier Loggia
  Solid Earth, 15, 895–920, https://doi.org/10.5194/se-15-895-2024, 2024
  This study characterizes the Tchirezrine II sandstone reservoir in northern Niger. Crucial for potential uranium in situ recovery (ISR), our multifaceted approach reveals (i) a network of homogeneously distributed orthogonal structures, (ii) the impact of clustered E–W fault structures on anisotropic fluid flow, and (iii) local changes in the matrix behaviour of the reservoir as a function of the density and nature of the deformation structure.

Extraction of pre-earthquake anomalies from borehole strain data using
Graph WaveNet: a case study of the 2013 Lushan earthquake in China
- Abstract: Extraction of pre-earthquake anomalies from borehole strain data using Graph WaveNet: a case study of the 2013 Lushan earthquake in China
  Chenyang Li, Yu Duan, Ying Han, Zining Yu, Chengquan Chi, and Dewang Zhang
  Solid Earth, 15, 877–893, https://doi.org/10.5194/se-15-877-2024, 2024
  This study advances the field of earthquake prediction by introducing an extraction method for pre-seismic anomalies based on the structure of Graph WaveNet networks. We believe that our study makes a significant contribution to the literature as it not only demonstrates the effectiveness of this innovative approach in integrating borehole strain data from multiple stations but also reveals distinct temporal and spatial correlations preceding earthquake events.

Quantifying mantle mixing through configurational entropy
- Abstract: Quantifying mantle mixing through configurational entropy
  Erik van der Wiel, Cedric Thieulot, and Douwe J. J. van Hinsbergen
  Solid Earth, 15, 861–875, https://doi.org/10.5194/se-15-861-2024, 2024
  Geodynamic models of mantle convection provide a powerful tool to study the structure and composition of the Earth's mantle. Comparing such models with other datasets is difficult. We explore the use of configurational entropy, which allows us to quantify mixing in models. The entropy may be used to analyse the mixed state of the mantle as a whole and may also be useful to validate numerical models against anomalies in the mantle that are obtained from seismology and geochemistry.

Palaeoseismic crisis in the Galera Fault (southern Spain): consequences in

- Abstract: Palaeoseismic crisis in the Galera Fault (southern Spain): consequences in Bronze Age settlements'
  Ivan Martin-Rojas, Ivan Medina-Cascales, Francisco Juan García-Tortosa, Maria Oliva Rodríguez-Ariza, Fernando Molina González, Juan Antonio Cámara Serrano, and Pedro Alfaro
  Solid Earth, 15, 837–860, https://doi.org/10.5194/se-15-837-2024, 2024
  We investigated prehistoric earthquakes produced by the Galera Fault (southern Spain) over the last 24 000 years. From this analysis, we deduced the basic parameters that allow for the characterization of the seismic hazard of this fault. Furthermore, we discuss how the Galera Fault is prone to producing seismic crises. We also propose that one of these crises could have been responsible for the abandonment of Bronze Age human settlements located near the fault.

Highlights on mantle deformation beneath the Western Alps with seismic
anisotropy using CIFALPS2 data
- Abstract: Highlights on mantle deformation beneath the Western Alps with seismic anisotropy using CIFALPS2 data
  Silvia Pondrelli, Simone Salimbeni, Judith M. Confal, Marco G. Malusà, Anne Paul, Stephane Guillot, Stefano Solarino, Elena Eva, Coralie Aubert, and Liang Zhao
  Solid Earth, 15, 827–835, https://doi.org/10.5194/se-15-827-2024, 2024
  We analyse and interpret seismic anisotropy from CIFALPS2 data that fill the gaps in the Western Alps and support a new hypothesis. Instead of a continuous mantle flow parallel to the belt, here we find a N–S mantle deformation pattern that merges first with a mantle deformed by slab steepening beneath the Central Alps and then merges with an asthenospheric flow sourced beneath the Massif Central. This new sketch supports the extinction of slab retreat beneath the Western Alps.

Rift and plume: a discussion on active and passive rifting mechanisms in
the Afro-Arabian rift based on synthesis of geophysical data
- Abstract: Rift and plume: a discussion on active and passive rifting mechanisms in the Afro-Arabian rift based on synthesis of geophysical data
  Ran Issachar, Peter Haas, Nico Augustin, and Jörg Ebbing
  Solid Earth, 15, 807–826, https://doi.org/10.5194/se-15-807-2024, 2024
  In this contribution, we explore the causal relationship between the arrival of the Afar plume and the initiation of the Afro-Arabian rift. We mapped the rift architecture in the triple-junction region using geophysical data and reviewed the available geological data. We interpret a progressive development of the plume–rift system and suggest an interaction between active and passive mechanisms in which the plume provided a push force that changed the kinematics of the associated plates.

Impact of stress regime change on the permeability of a naturally
fractured carbonate buildup (Latemar, the Dolomites, northern Italy)
- Abstract: Impact of stress regime change on the permeability of a naturally fractured carbonate buildup (Latemar, the Dolomites, northern Italy)
  Onyedika Anthony Igbokwe, Jithender J. Timothy, Ashwani Kumar, Xiao Yan, Mathias Mueller, Alessandro Verdecchia, Günther Meschke, and Adrian Immenhauser
  Solid Earth, 15, 763–787, https://doi.org/10.5194/se-15-763-2024, 2024
  We present a workflow that models the impact of stress regime change on the permeability of fractured Latemar carbonate buildup using a displacement-based linear elastic finite-element method (FEM) and outcrop data. Stress-dependent heterogeneous apertures and effective permeability were calculated and constrained by the study area's stress directions. Simulated far-field stresses at NW–SE subsidence deformation and N–S Alpine deformation increased the overall fracture aperture and permeability.

Various lithospheric deformation patterns derived from rheological

simulations
- Abstract: Various lithospheric deformation patterns derived from rheological contrasts between continental terranes: insights from 2-D numerical simulations
  Renxian Xie, Lin Chen, Jason P. Morgan, and Yongshun John Chen
  Solid Earth, 15, 789–806, https://doi.org/10.5194/se-15-789-2024, 2024
  Continental terranes have various rheological strengths due to the differences in their ages, compositions, and structures. We applied four assumed rheological models to three terranes in a collisional model and obtained four styles of lithosphere deformation patterns of collision, subduction, thickening/delamination, and replacement. These simulation patterns are seen in observed lithosphere deformation patterns and structures in East Asia.

Propagating rifts: the roles of crustal damage and ascending mantle fluids
- Abstract: Propagating rifts: the roles of crustal damage and ascending mantle fluids
  Folarin Kolawole and Rasheed Ajala
  Solid Earth, 15, 747–762, https://doi.org/10.5194/se-15-747-2024, 2024
  We investigate the upper-crustal structure of the Rukwa–Tanganyika rift zone in East Africa, where the Tanganyika rift interacts with the Rukwa and Mweru-Wantipa rifts, coinciding with abundant seismicity at the rift tips. Seismic velocity structure and patterns of seismicity clustering reveal zones around 10 km deep with anomalously high Vp / Vs ratios at the rift tips, indicative of a localized mechanically weakened crust caused by mantle volatiles and damage associated with bending strain.

  Solid Earth, 15, 731–746, https://doi.org/10.5194/se-15-731-2024, 2024
  This study improves geochemical mapping by addressing the uncertainty in defining element associations. It clusters the study area by element similarity, recognizes elemental associations for each cluster, and then detects anomalies indicating underlying geological processes. This method is applied to a region in China, confirming its effectiveness and consistency with the geology. This study can enhance geochemical mapping for mineral exploration and improve geological-process understanding.

  Solid Earth, 15, 711–729, https://doi.org/10.5194/se-15-711-2024, 2024
  Global gravity data are used to develop 2D models and a Moho depth map from 3D inversion, depicting the crustal structure below the region covered by Proterozoic sedimentary basins, south of the Bundelkhand Craton in central India. The observed thick mafic underplated layer above the Moho indicates Proterozoic plume activity. Thus, the study offers insights into the crustal configuration of this region, illustrating the geodynamic processes that led to the formation of the basins.

  J. Kim Welford
  Solid Earth, 15, 683–710, https://doi.org/10.5194/se-15-683-2024, 2024
  I present a synthesis of the continent–ocean boundaries of the southern North Atlantic Ocean, as probed using seismic methods for rock velocity estimation, to assess their deep structures from the crust to the upper mantle and to discuss how they were formed. With this knowledge, it is possible to start evaluating these regions of the Earth for their capacity to produce hydrogen and critical minerals and to store excess carbon dioxide, all with the goal of greening our economy.

- Abstract: Cretaceous–Paleocene extension at the southwestern continental margin of India and opening of the Laccadive basin: constraints from geophysical data

  Solid Earth, 15, 671–682, https://doi.org/10.5194/se-15-671-2024, 2024
  The study identifies evidence for extension south of Tellicherry Arch along the southwestern continental margin of India through the integrated analysis of multichannel seismic and gravity data. The sediment deposition pattern indicates that this extension occurred after the Eocene. We further propose that the anticlockwise rotation of India and the passage of the Réunion plume have facilitated the opening of the Laccadive basin.

  Solid Earth, 15, 657–669, https://doi.org/10.5194/se-15-657-2024, 2024
  In this manuscript, we investigate the complexity of the upper-crustal block of the Central Anatolia region, Türkiye. We present the results of seismic attenuation by examining 1509 local earthquakes recorded at 72 broadband stations and deployed within the framework of a passive seismic experiment. We emphasize the detailed 2D maps of intrinsic and scattering attenuation within the area where two devastating earthquakes (M1 7.8 and M1 7.5 Kahramanmaraş Earthquake Sequence) happened in 2023.

  Solid Earth, 15, 639–656, https://doi.org/10.5194/se-15-639-2024, 2024
  The Basal Complex unit on Fuerteventura island comprises magmatic rocks showing significant rare Earth element (REE) concentrations with values up to 10 300 ppm REY (REEs plus yttrium). We carried out mineralogical and geochemical analyses, but additional research is needed to fully understand their distribution due to structural complexities and environmental factors.

  Solid Earth, 15, 617–637, https://doi.org/10.5194/se-15-617-2024, 2024
  Heat flux heterogeneities at the bottom of Earth's mantle play an important role in the dynamic of the underlying core. Here, we study how these heterogeneities are affected by the global rotation of the Earth, called true polar wander (TPW), which has to be considered to relate mantle dynamics with core dynamics. We find that TPW can greatly modify the large scales of heat flux heterogeneities, notably at short timescales. We provide representative maps of these heterogeneities.

  Smøla island, in the mid-Norwegian margin, has complex fracture and fault patterns resulting from tectonic activity. This study uses a multiple-method approach to unravel Smøla's tectonic history. We found five different phases of deformation related to various fracture geometries and minerals dating back hundreds of millions of years. 3D models of these features visualise these structures in space. This approach may help us to understand offshore oil and gas reservoirs hosted in the basement.

  Simulations of subducting tectonic plates often use material properties extrapolated from the behavior of small rock samples in a laboratory to conditions found in the Earth. We explore several typical approaches to simulating these extrapolated material properties and show that they produce very rigid subducting plates with unrealistic dynamics. Our findings imply that subducting plates deform by additional mechanisms that are less commonly implemented in simulations.

  The Ellsworth Mountains, situated in a remote area of Antarctica, span 350 km in length and 50 km in width, encompassing Antarctica's tallest peak. Due to their isolated location, understanding their formation has been challenging and remains incomplete. Our analysis of zircon minerals from the Ellsworth Mountains indicates that the mountain chain formed between 180 and 100 million years ago, contributing to our understanding of their formation.
