Description
The Tantalite Valley Complex, a poorly mineralised (Cu and Ni sulphides) body of roughly concentric peridotite-gabbroid intrusions was emplaced along a major zone of dislocation (the Tantallite Valley Lineament) into a metasedimentary sequence of migmatites and gneisses which, together with the complex, have experienced a complex metamorphic and tectonic history. A number of large mineralised pegmatites (producers of minerals of Nb, Ta, Bi, Li and Be over the past two decades), was intruded about 1000 Ma ago

Die Kompleks Tantalietvallei bestaan uit 'n swak gemineraliseerde (Cu- en Ni-sulfiede), min of meer konsentriese, intrusiewe liggaam wat langs 'n baie groot breuksone (die Lineament Tantalietvallei) in 'n metasedimentere opeenvolging van migmatiete en gneisse ingedring het. Al bogenoemde gesteentes het 'n komplekse metamorfiese en tektoniese geskiedenis. 'n Aantal groot gemineraliseerde pegmatiete is ongeveer 1000 Ma gelede ingedring, en het minerale van Nb, Ta, Bi, Li en Be in die afgelope twee dekades gelewerFiles
