Geological Characteristics and Exploration Indicators of the KANO Tin-Tantalum Iron Sand Deposit in Nigeria
The KANO tin-tantalum iron sand deposit is situated in the central Nigeria Jos Plateau region.The deposit is part of the Jos-Bauchi gold,niobium-tantalum,and polymetallic metallogenic belt,which includes cassiterite,among other minerals.The ore bodies are primarily found within Quaternary loose sand(gravel)layers,clay layers,and clayey(silty)gravel layers.The ore bodies exhibit an elongated slab-like form,measuring 1 273 meters in length,40 to 250 meters in width,and 0.50 to 2.78 meters in thickness,extending from north to south across the entire mining area.The deposit is a Quaternary secondary sedimentary mineral resource,with the main heavy sand minerals being cassiterite,columbite-tantalite,ilmenite,zircon,monazite,etc.The source of the ore-forming materials is mainly attributed to the weathered and loosely deposited porphyritic biotite monzonitic granite and fine-medium grained biotite-hornblende monzonitic granite from the nearby Jos Plateau.These materials are transported by water flow into the basin,deposit,and concentrate to form floodplain alluvial placer deposits.
