Zeolite Mineralization Prospect within the Basalts of Tim-Kwalla, Jos Plateau North Central Nigeria

Abstract

Detailed geological mapping of part of Kwolla Sheet 211 NE on scale 1:50,000 was carried out. Mapping revealed that Tim-Kwalla Basalts occur as pyroclastics in form of boulders in a ring pattern and also as “flow” basalts as seen along stream channels. Three petrographic rock types are presented in the area; The Granite-gneiss, the Biotite granite and the Newer Quaternary basalts. Some major oxides were determine through XRF geochemical analysis which include SiO2, Al2O3, K2O, Fe2O3 and CaO. Plots from the major oxides suggest the Tim-Kwalla Basalts to be of pre-plate collision petrogenetic source having high Fe tholeiitic Basalts. XRF geochemical of the white crystalline substance revealed the presence of Ca-rich zeolite in form chabazite and phillipsite
