The epigenetic Pb-Zn deposits of the southern Benue Valley (Nigeria) are localized within Cretaceous sediments of an intracontinental rift basin. Fluid inclusion studies of vein minerals from the Abakaliki and Ishiagu orebodies show that sphalerite and quartz were deposited at relatively low temperatures (102–175 °C) with ore-fluid salinity mostly in the range of 17–25 equiv. wt NaCl

Abstract. The Benue trough is an intra-continental rift initiated in the Cretaceous during the opening of the South Atlantic Ocean. Lead-zinc-barite-fluorite mineralization occurs along the 600 km axis of the trough in three discrete sub-basins which coincide with the lower middle and upper mineral districts of the Benue Valley.

LEAD-ZINC MINERALISATION OF THE BENUE TROUGH One of the major features of the Benue Trough is the central zone of lead-zinc mineralisation which is about 80 km wide and extends from Abakaliki in the south to Zurak in the northeast a distance of about 560 km (Fig. 1). The mineralisation tends to be restricted to strata of Albian to Cenomanian age.
