Update on carbonatites of South Africa and Namibia

Verwoerd W.J. (1993)

Brief descriptions are given of 43 carbonatite occurrences with emphasis on information that has come to light since 1967. This includes previously unpublished data on Keikamspoort, Welgevonden, Goudini, Mickberg, Weltevrede, Garub, Bokiesbank, Keishohe, Teufelskuppe, and Kaukausib. The descriptions attempt to summarize data like location, size, geology, mineralogy, geochemistry, and geochronology of each carbonatite occurrence, if available. They are grouped in five age groups showing little overlap, ranging from early Proterozoic to Tertiary, and it is concluded that the subcontinent does not show a pattern of repeated alkaline-carbonatitic activity at the same place. Some doubtful and discredited cases are also mentioned. -Author
