| dc.description.abstract | The distinct lateritic profiles around "Kano Metropolis" were investigated using combined geological and geochemical methods. The area studied is a part of north-central basement complex of Nigeria, and is underlain mainly by the rocks of "Older Granite Suite" (Danbatta, 1985). Laterization in the area was found to be controlled by lithology and drainage. Lateritic profiles studied were identified into three types:- high-land, low-land and footslope iaterites and were distinguished into four horizons from bottom to top; fresh bedrock, saprolite, mottled and indurated layers. Multivariate statistical methods involving correlation and accumulation factor (AF) were employed in interpretation of geochemical data. The correlation pattern of elements in the lateritic profiles was found to vary with the type of bedrocks and maturity of lateritic horizons. The lateritic horizons are strongly depleted of K, Ca, Rb, and Sr and enriched by Fe, Zr, Mo, Cu, and Pb relative to the parent rock. Accumulation factor (AF) values indicate a possible concentration of V, Cr, Mn, Co, and Ni in lateritic profiles, especially in indurated and mottled horizons. In terms of their potential for mineralization, the mottled and indurated horizons of lateritic profile overlying diorite hold good promise for concentration of V, Cr, Mn, Co and Ni. The indurated layer of granite-derived lateriti profile also shows potential for concentration of Cu, Mo and Pb. Similarly, the saprolite layer of the same profile shows good promise for concentration of Zn. | en_US |
