Abstract
Abstract The different stages of the geodynamic evolution of Neoproterozoic basins in southwestern Africa were accompanied by a variety of mineralisation processes. These range from synsedimentary-exhalative base metal deposits in continental rift basins, Besshi-type cupriferous pyrite deposits in oceanic crustal rocks, syn-orogenic polymetallic Tsumeb-type mineralisation in foreland carbonate platforms, orogenic gold and magmatic U and Sn deposits, to REE-rich pegmatites and post-orogenic enrichment in the supergene zone. Of currently main economic significance amongst these are the Pb and Zn deposits around Rosh Pinah in the external Gariep Belt, the Tsumeb-type deposits at Kombat and the alaskite-hosted U deposits in the western part of the Central Zone in the Damara Belt.
