Abstract: Groundwater serves as the primary source of potable water in Maiduguri and Jere, northeastern Nigeria, where rapid population growth and limited public water supply have intensified reliance on hand-dug wells and boreholes. However, the increasing dependence on on-site sanitation systems such as pit latrines and septic tanks has raised concerns about groundwater safety. This study investigates the impact of excreta disposal practices on groundwater quality in the region, focusing on nitrate concentrations, thermotolerant coliforms (TTC), separation distances between wells and sanitation facilities, and groundwater flow patterns.......

Abstract: In its long history, our planet has undergone massive changes in climate with varying causes, and understanding the details of these events could provide a more robust framework for predicting future climate change. Earth's climate has never been static. Long before human civilization emerged, our planet experienced dramatic swings between ice ages and greenhouse periods — all recorded in the rock record. Geology offers an unparalleled......

Abstract: Late Quaternary sediments of the Chad Formation exposed around Magumeri in northeastern Nigeria were investigated to determine their mineralogical composition, provenance, weathering history, depositional environment, and economic potential. Thirteen representative sediment samples were analysed using X-ray diffraction (XRD) and X-ray fluorescence (XRF). Quartz (25.9–62%) dominates the detrital mineral assemblage, while feldspars....

| Title | : | The Himalayan Ellipse Model: Finite Element Analysis (FEA) Approach |
| Country | : | India |
| Authors | : | Amitabha Roy |
|
: | 10.9790/0990-1402012429 |
Abstract: This study employs Finite Element Analysis (FEA) to investigate the complex crustal deformation, uplift, and
erosion patterns within the Himalayan syntaxial bends, specifically at Nanga Parbat (west) and Namcha Barwa
(east). These "hairpin" turns, heavily influenced by the northward, counter-clockwise rotation of the Indian
Plate, are simulated using continuum mechanics and viscous/viscoelastic material properties. The Himalayan
arc, characterized by an elliptical shape, is modeled with a semi-major axis of 1200 km and pinned at its ends
by major strike......

Abstract: An integrated analysis of core-derived facies and well-log petrophysical data was carried out to characterize the reservoir architecture of the GABO Field in the onshore Niger Delta Basin. Detailed core descriptions were used to identify lithofacies based on grain size, lithology, and sedimentary structures. Six lithofacies were recognized, including trough cross-bedded sandstone, planar cross-bedded sandstone, ripple-laminated sandstone, horizontally......

| Title | : | Application of GMM in fluid geochemistry of Indian hot springs using PCA factor score data |
| Country | : | India |
| Authors | : | Amitabha Roy |
|
: | 10.9790/0990-1402015867 |
Abstract: This study applies Gaussian Mixture Models (GMMs) to the fluid geochemistry of Indian hot springs, utilizing Principal Component Analysis (PCA) factor score data. GMMs, a type of unsupervised machine learning model, represent data as a mixture of multiple Gaussian distributions, allowing for soft clustering and nuanced data interpretation. The model's parameters, including means, covariances, and weights, provide a comprehensive representation of data distributions. By interpreting the multidimensional GMM through scatter plots and confidence ellipses, this research enhances our understanding of geothermal systems and identifies patterns......

Abstract: Background: This study evaluates the engineering suitability of lateritic soils from Oyigbo, Niger Delta, for use in road pavement subgrade and sub-base layers, given the need for locally available construction materials that satisfy Nigerian pavement performance specifications. Materials and Methods: Five soil samples were obtained from georeferenced locations and subjected to standard laboratory testing, including natural moisture content, Atterberg limits, particle size distribution, compaction characteristics (OMC and MDD), and California Bearing Ratio (CBR) under soaked and unsoaked conditions, consistent with established soil-testing standards.......

Abstract: The area around Gupteswar Cave, which is situated along the Eastern Ghats, has a variety of structural and geomorphological characteristics that provide insight into the formation of karst and the evolution of the landscape. The systematic analysis of surface geological features, such as joints, faults, bedding planes, sedimentary dykes, potholes, stromatolitic structures, and characteristic weathering patterns like crocodile-skin textures, is the main emphasis of this study. The results emphasize the Gupteswar region's importance as a Geoheritage site with potential for more geological and geomorphological research and advance knowledge of the link between structural geology and geomorphology.
