Mineralogical Characterization of the gold-bearing rocks around Okemesi-Ijero Area, Southwestern Nigeria. []


The mineralogical characterization of the gold bearing rocks around Okemesi-Ijero, South Western Nigeria was carried out using Petrographic and X-ray diffraction (XRD) studies to determine the mineralogical phase of the gold showings. Various researchers have worked in the studied area most especially Ayodele et al., (2017), who carried out geochemical analysis (XRF) on the bedrocks, indicating showings of gold mineralization in Okemesi (Ajindo) with concentration values of 10-0.05ppm. This prompted the investigation for confirmation of gold mineralization on the bedrocks of Okemesi area (Ajindo). The method of investigation included systematic geologic mapping of the various lithologies, sampling of the various lithologic units at a density of one sample per 100sqkm, followed by petrographic studies using light transmitting Petrological Microscope and mineralogical characterization of the various rocks using X-ray diffraction techniques (XRD). Twenty-six (26) rock samples were collected from the studied area, and were prepared for thin section using the standard procedures. However, seven (7) out of the samples majorly schistose and massive quartzites were selected and prepared for XRD analysis. The results of the petrographic studies revealed the dominance of the following minerals from four major rock types (schistose and massive quartzites, granites and pegmatites) such that quartz has the highest percentage (62.29%), followed by the feldspars such as microcline (18.59%), plagioclase (6.89%), Orthoclase (0.82%), muscovite (15.71%), biotite (14.85%), opaque (3.47%), hornblende (1.12%), and mymakite (0.36%).The X-ray diffractograms confirmed the presence of gold (Petrovskaite) in the Ajindo schistose quartzites. The schistose quartzites exhibited poor foliation which prevented the flow of auriferous hydrothermal fluid into the host rock. Further studies can be carried out by using Micro X-ray Spectral Analysis to determine the concentration of the gold (petrovskaite) present in the host rock.

Numerical Analysis of Earth Slopes Using Finite Element Program []


The sustainability of the earth’s topography is a major concern in geotechnical engineering. Nowadays there are a number of computer-based geotechnical software that is used for slope stability analysis. For slopes with known geometry and soil parameters, computer-based slope stability analysis is a simple task for engineers. Computational software based on limit equilibrium principle has been in practice for many years. Likewise, software based on finite element approach has become a crucial tool for both researchers and professionals. The finite element is becoming well accepted, particularly the FE program Plaxis [1]. Since the finite element program utilizes stress-strain relationships, more practical stress redistributions are computed even for a sophisticated problem. In addition, the concept of slices is not applicable in the finite element approach and there is no need for assumptions of interslice forces. Unlike the LE approaches, the shape and location of the failure surface are not assumed prior to analysis. This makes the analysis of slope stability with FE methods more advantageous than LE methods. The objective of this study is to compare the applicability of the two-dimensional finite element program Plaxis 2D, for the analysis of pore water pressure, deformations and slope stability, with other finite element and limit equilibrium programs.
