Assessment of morphological and geological environment of manganese containing area in South West of Côte d'Ivoire
Journal Title: Journal of Biodiversity and Environmental Sciences (JBES) - Year 2013, Vol 3, Issue 1
Abstract
The vast majority of manganese indices in the southern Ivorian are closely associated with the birimian formations. Manganese containing formations are mainly located in the upper part of the birimian, particularly in a volcanic and sedimentary environment. Indeed, the Guitry environment includes sedimentary, volcanosedimentary, and metamorphic formations intruded into various granitoids. Their alteration leads to three major genetic types of minerals: ore in forms of interstratified lenses in the schist from direct oxidation of gondites; dismantling ore from these lenses, forming clusters of blocks, resulting from in situ fragmentation of the previous ore; hardened ore linked to the process of alteration and leaching of the above mentioned ores, then a concentration of manganese following a lateritic type pedological profile. The most economically interesting deposit consists of dismantling surface areas, including highly enriched clusters (90 % of exploitable ore), where manganese is found only in the form of secondary oxides, packaged in a clay soil. During the eburnean orogenesis, the initial manganese containing sediments were transformed to varying degrees in metamorphic rocks. Soils derived from the alteration of these birimian rock formations are known as brunified soils.
