Ageophysical Imaging for Geothermal Baringo Area using Magnetic Prospects Method
Ground magnetic survey in Lake Baringo area will be carried out to image the subsurface geology unci delineate areas associated with high temperature reservoir. In this study, tectonic lineaments and permeability around Lake Baringo Geothermal prospect is investigated in order to explore its potential using ground magnetic method. This is clone on the basis of the anomalies in the earth's magnetic field resulting from the magnetic properties of the underlying rocks. Magnetic susceptibility Of the rocks, which decrease with increase in temperature, varies depending on the type of the rock and the environment it is in. The field stations will be positioned using a 8 software and contour map computed to establish the magnetic signature of the area. Forward modeling will then be done using Mng2dc software, along selected profiles in the study area. This will attempt to identify possible presence and depths of anomalous bodies that may be heat sources and fluid trapping structures in the subsurface. Global positioning system (GPS) device. The total magnetic field intensities will then be measured using G-856 proton precession magnetometer with an accuracy of ± O.S gamma. Data reduction will be done to correct for di urnal and geomagnetic variations. Gridding will then be done using surfer.
