Geochemistry of termite mounds in the sediment-hosted Lead-Zinc Mining District of Yolo, Gongola Sub-basin: A guide for lead-zinc exploration in the Upper Benue Trough, Nigeria

Yolo lead-zinc mining district is an important area in Gongola Sub-basin of the Upper Benue Trough with paucity of rocks outcrops but abundant termite mounds. The termite mounds and their adjoining surface soils were analyzed for Pb, Zn, Ti, Cu, Sb, As, U, Cr, Zr and Li in an attempt to test their effectiveness in defining favorable areas for lead-Zinc mineralization in the Upper Benue Trough. The result shows a general...

Lithological features and chemical characterization of metamorphosed carbonate rocks in Igue, Southwestern Nigeria

This paper investigates and reports the lithological and compositional features of Igue marble deposit in southwestern Nigeria. The deposit occurs as low-lying heterogeneous units under a humus-laden dark brown tropical soil within Igarra Schist Belt on south eastern flank of basement complex of southwestern Nigeria. The marble deposit occurs as lenses sandwiched between quartz-biotite schist, calc-silicate gneiss and...
