Mile Bugarin

Abstract

This work presents the geological structure of the Chipupushi area which is located on the border between the Northwestern Province and Copperbelt Province in the Republic of Zambia. Geological structure of the Luswishi dom e, within which the Chipupushi area is, consists of: Igneous rocks, the complex of ultra basic, basic, intermediate and acid magmatic rocks, the Basement Complex, which was built of schist, gneiss, granite - gneiss and subordinated pegmatite as well as the Katanga super group out of which the Chipupushi formation was separated. On the bank of the river Chipupushi, within the Chipupushi formation, in the period between 1969 and 1970, two dr illholes MP 490 and MP 491 we re drilled. The oldest drilled rocks by these drillholes are the Basm ent granites, granite gneisses and minor schists. Series of arenites with minor schist s, siltstones and conglomerates lie over the Basement granites. Rare mineralization of malach ite, chrysocolla, aute nite and meta to rbernite in the wethered zone has been identified in the cores of these drill holes as well as bornite and chalcopyrite in association with uranite in depth.
