Origin of lead-zinc mineralization in the southern Benue,

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 17–25Lead Ore Mineral Deposits in Nigeria with their Locations,,Galena is a shiny grey, heavy metallic sulphide (PbS) from which lead ore is commonly found. It remains one of the widely distributed sulfide minerals, and the most abundant of all. Today, this lead ore, galena, is mined at many locations across the globe, making up all of the ores mined presently.

Early Mining: A Brief History • Lead Mining in the,

As the water cools minerals are deposited in crystal form and galena (the mineral form of lead ore) is just one of many minerals to be deposited. Others include calcite, fluorspar, barites and pyrites. There is evidence of the use of lead in the Dales dating from the time of the Roman Emperor Trajan (117-138 CE) in the form of 'pigs' of lead (moulded blocks of lead) markedUntapped minerial resources in Benue State – I am Benue,26.03.2013· Untapped minerial resources in Benue State.
