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

The lead-zinc lodes in the Benue Trough carry small amounts of fluorspar which also occur in tin veins in the younger granites. Impure graphite is known in the younger metasediments near Birnin Gwari in Kaduna State, Taraba and Adamawa States, at Hayna (Ningi) in Bauchi State and in the Obudu area of Cross River State.

Alteration Mapping for Lead-Zinc-Barium Mineralization
The Benue Trough galena-sphalerite-baryte occurrences are formed by open space filling in faults, hence they are generally considered to be epigenetic fracture filling deposits (Ezepue 1984; Oha et al. 2017).
