(2011) THE GEOLOGY AND GEOCHEMISTRY OF ANGWAN MALLAM AND ENVIRONS, KEFFIhttps://keffi.nsuk.edu.ng/handle/20.500.14448/5725The Geology and geochemical mapping ofl atitude N 08° 51l, N 08° 45land longitude E 007° 45', E 008° Od of Nigeria North Central Part of Keffi Sheet 208 NE. Thin section of the various rock types in the study area were carried out, with migmatite, granodiorite, pophyritic granodiorite, and biotite gneiss intruded by mineral bearing pegmatite dyke were identified. Structures like fault, vein, joint and foliations were also observed during the field mapping and they trend NE - SW”. Geochemical analysis of the rocks using x-ray fluorescent techniques reveals the concentration of Potassium, Calcium, Titanium, Manganese, Iron, Copper, Nickel, Zinc, Arsenic; Robidium and Strontium. The structural trend of the rocks conforms to the general pan-African Orogeny deformation. Mining activities in some of the villages does not contaminate or pollute its water, soil and wellbeing of the people living in Agwan Mallam. This study reveals some major elemental composition of rocks across Agwa Mallam and its environs and how they are distributed. The findings will be a benefit to Environmental Impact Assessment of Agwa Mallam and further research is hereby recommended on the Hydrochemistry with special emphasis on water contamination due to leached ion from rockenArticle
