摘要

This paper presents a summary of the research carried out within the southern terminal of Zuru-Yauri Schist belt, an area enclosed by latitude 10.000 to 10.300 and longitude 4.000 to 5.000 using Aero-magnetic and Aero-radiometric data. Regions that has suffered hydrothermal alterations due to potassium enrichment and Thorium depreciation were mapped and interpreted as regions of orogenic gold mineralization. Nine major fault lines were identified, a major fault labelled F8 trending NE-SW, runs diagonally for about 70 km. Regions of hydrothermal alteration were evaluated from K/Th ratio, K-deviation and F-parameter. Analysis and interpretation of the ternary image indicate that regions where high K/Th values (0.3–0.5) %/ppm, high k-deviation values (7.3–60.6) and high F-Parameter values (0.8–1.3) appears as white on the colour aggregate, an indication of high hydrothermal altered zone. Area with grey colour indicating moderately altered zone. Regions that appears as dark colour indicate low values of K/Th, K-deviation and F-Parameter this occurs within the sedimentary formation of Bida Basin sand stone, located at the Northern end and South Eastern corner of the study area. A comprehensive analysis of these results delineated region of hydrothermal altered zones in white and grey colour that coincides with areas within the faulted and fractured basement. The research concluded by delineating regions in which structures from the magnetic data that coincide with regions of potassium-altered hydrothermal zones are marked as regions for orogenic gold mineralisation haloes. These regions are within Luma, Tungan-Dangaje, New Busa, Ferin Ruwa, Gwagwade, Kinke, and Kado villages, of which part of them harbors artisanal miners.
