Abstract

Petrographical and mineralogical characterization of manganese nodules around Madaka, north central Nigeria has been examined using ore microscopy and X-ray Diffraction for the clay in the study area. These rocks comprise of (migmatitic gneiss, banded gneiss and granitic gneiss, kyanite-sillimanite schist, semi-pelitic schist; amphibolites, talcose rock, quartzite, and phyllite, granodiorite, fine-medium-grained granites and porphyritic granite. Manganese nodules were found as concretions of different size dispersed in a variegated clay as hosted by kyanite silimanite schist. The ore microscopy of manganese nodules reveals spessartine, cryptomelane / birnessite, jianshuite, and pyrolusite as major minerals. The gauges in the studied nodules constitute calcite, hematite, a trace of quartz and pyrite. The X-ray Diffraction of the clay indicates the presences of Illite/mica, smectites and kaolinite/halloysite as major minerals. Traces of mn and quartz were observed as gauge in the clay. The mn nodules in Madaka area are apparently controlled by physico-chemical factors (environment, 
heat and water). The appearance of pyrolusite and cryptomelane at an intermediate stage of oxidation rather than end product is considered the result of the acidic environment and the high potassium content of the host rocks. The source of the manganese nodules around Madaka area is at a considerable distance and consisted probably of a moderately basic igneous or metamorphic rock, which underwent disintegration, leaching and, the manganese nodules being transported in solution to its present state under influence of redox reaction through hydrothermal process.
