- Lithological features and chemical characterization of metamorphosed
carbonate rocks in Igue, Southwestern Nigeria
Abstract: This paper investigates and reports the lithological and compositional features of Igue marble deposit in southwestern Nigeria. The deposit occurs as low-lying heterogeneous units under a humus-laden dark brown tropical soil within Igarra Schist Belt on south eastern flank of basement complex of southwestern Nigeria. The marble deposit occurs as lenses sandwiched between quartz-biotite schis...

- Geochemistry of termite mounds in the sediment-hosted Lead-Zinc Mining
District of Yolo, Gongola Sub-basin: A guide for lead-zinc exploration in
the Upper Benue Trough, Nigeria
Abstract: Yolo lead-zinc mining district is an important area in Gongola Sub-basin of the Upper Benue Trough with paucity of rocks outcrops but abundant termite mounds. The termite mounds and their adjoining surface soils were analyzed for Pb, Zn, Ti, Cu, Sb, As, U, Cr, Zr and Li in an attempt to test their effectiveness in defining favorable areas for lead-Zinc mineralization in the Upper Benue Troug...

- Numerical and laboratory investigation of effect of soil reinforcement on
settlement of strip foundations
Abstract: Reinforcement of loose soils with geosynthetics in order to achieve a strengthened soil-reinforcement system, with enhanced tensile strength and reduced settlement is an important subject in the field of geotechnical engineering. In this study, a soil reinforcement system was used to increase the bearing capacity of sandy soil beneath a strip foundation. A small-scale laboratory model was bu...

- LA-ICP-MS and EMP relationships in pyrite grains from Barberton Greenstone
Belt, South Africa: An attempt for quantification
Abstract: Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS) count per seconds (cps) results were tested for quantification, using the same spot analyses of Electron Microprobe Analyses (EMP) in weight percentage (wt. %); they were obtained from selected pyrite grains from Sheba, New Consort, and Fairview gold mines of the Barberton Greenstone Belt (BGB). Theoretically, data obtai...

- Coarse-grained rutile from regolith in Ebensuk west of Tinto, Cameroon
Abstract: Coarse rutile with some grains exceeding 32 mm was recovered from regolith excavated from three pits (ABC) at Ebensuk. The rutile concentration ranges from 2.53 kg/m3 of regolith material in Pit C to 2.83 kg/m3 in Pit B with an average of 2.66 kg/m3. The rutile is black, longitudinally striated, with a metallic to adamantine luster and hard. Results of grain size (Z) analysis show that the r...

- Sequence stratigraphic study of ‘X’ field in eastern
offshore of Niger Delta, Nigeria
Abstract: An integrated approach to Seismic interpretation that combines techniques of sequence stratigraphic analysis, seismic facies analysis and attribute analysis is one of the most effective approaches for hydrocarbon exploration in growth-faulted deltaic strata of offshore eastern Niger Delta. These strata are generally thick paralic/marine units deposited along an unstable progradational contin...

- Migmatization process and the nature of transition from amphibolite to
granulite facies metamorphism in Ikare area south western Nigeria
Abstract: The Ikare area is underlain by rocks of the migmatite-gneiss-quartzite complex and older granite lithologic groups and charnockites. Categorization of these rocks in the literature and published map is generalized and the rocks are undifferentiated. Though reported in few literature as an area with rocks composed of granulite facie grade, the nature of transition is not well documented. Fiel...

- Petrological characteristics of some cretaceous igneous rocks, in
Southwest of Gboko, Southern Benue Trough, Nigeria
Abstract: Detailed field geological mapping, outcrop petrography and thin-section microscopy are employed to delineate and describe igneous rocks, and to infer the tectono-magmatic and geochemical constraints affecting their emplacement in the Tse-Agberagba area, Southwest of Gboko, Southern Benue Trough. Magmatic activity, coupled with folding and deformation were the effects of the Santonian tectoni...

- The geotechnical properties of the oolitic ironstone formation, Wadi
Halfa, North Sudan
Abstract: Wadi Halfa Oolitic Ironstone Formation (WHOIF) covers large areas around Wadi Halfa border town in Northern Sudan. The detrital framework grains of sandstone of WHOIF are composed of sub-angular to sub-rounded quartz grains followed by feldspars, lithic fragments, micas and heavy minerals. The dominant cementing materials are iron oxides, carbonate cement, and some clay minerals. Twelve bloc...

- Anisotropic properties of the near-surface in South-Western Niger Delta:
Implications on geotechnical constructions
Abstract: The near-surface anisotropic properties within the South-Western Niger Delta were investigated to determine their impacts on geotechnical constructions. Uphole data analyses reveal a weathered layer that is thickest in the NW, E and SE with an average of 4.2 m and thinnest in the North-Central with a value of 3.8 m; a sub-weathered layer that is thickest in the NW and SW with an average of 3...
