ABSTRACT Integration of 2D geophysical methods, Electrical Resistivity Imaging (ERI) and Induced Polarization (IP) were used to study the subsurface geology and structures around Ihe pond, Nsukka in Anambra basin. The research work has delineated the geologic structures and strata responsible for the water in the pond, and determined the origin of the Pond. Three 2D resisitivity profiles of maximum spread lengths of 500, 400 and 500m were run around the pond. Horizontal profiling, using Wenne...
ABSTRACT ͦ Many areas are exposed to different types of natural hazards including landslides, which can lead to loss of lives, injury to people, damage to property and disruption of economic activities. This project assessed the landslide susceptibility and quantifies the hazard and risk related to landslides in Okemesi, southwest, Nigeria using remote sensing imageries and geographic information system (GIS). The result revealed that slope, elevation, aspect, distance from road can ...
A total of 21 samples were analyzed in the laboratory, Inductively Coupled Plasma-Atomic Emission Spectrum (ICP-AES) was employed in the whole rock analysis for oxides, total sulphide (TOS), total carbon (TOC) and loss on ignition (LOI), while Inductively Coupled Plasma-Mass Spectroscopy (ICP-MS) was employed in the analysis for trace metals including gold, and rare earth elements (REE) that were either associated with or served as pathfinder for gold. Statistical analyses revealed an anomaly...
Field relationship, petrographical studies and geochemical analysis were combined in investigating the depositional environment and industrial viability of limestone beds in Purechem’s quarry at Onigbedu. Field observation indicates a homogenous lithology of the beds with variation in textural and clastic composition. Petrographic study revealed that the limestone falls under the Biospamicrite and Wackestone classification based on the works of Folks, (1959) and Dunham, (1962) respectively....
