This event has been postponed until further notice.


The SEG's 2020 Centenary transect in Africa will cover over 3000 km, traversing down the length of Namibia and into the west-central parts of South Africa. The transect will focus on two key aspects of the continent’s fascinating geology and spectacular mineral endowment by combining a classic Pan African-to-Archaean crustal evolution profile with visits to some of the region's world-class mineral deposits. The tectonic setting of a variety of ore deposit types and their formation as a function of the evolution of the southern African sub-continent is the theme of this SEG 2020 Regional Centenary Event. This trip will appeal to all industry and academic geologists, offering a scope that covers every niche in the vast geological panoply that is Africa.

The transect will commence in Windhoek, Namibia, on June 16, 2020, and drive northwards to visit the Otjikoto gold mine and the Uis tin-tantalum mine in the northern portion of the ca. 500 Ma Pan-African orogen. The trip will then head southwards to see both the Rössing and Husab uranium deposits near Swakopmund. The route will then pass through the famous Sossusvlei dune fields of the Namib desert before visiting the Skorpion Zn-Pb mine to the north of Rosh Pinah. Once having crossed into South Africa, and into the ca. 1100 Ma Namaqua orogenic belt, the trip will pass through the classic deposits of the Okiep copper district. Heading eastwards, a visit will then be made to the Gamsberg Zn-Pb mine that is hosted in Palaeoproterozoic metasediments. Arriving eventually onto the Archaean Kaapvaal Craton, the transect will examine the giant manganese mines of the Postmasburg district and then diamondiferous kimberlite at Finsch, before terminating in Kimberley on June 25, 2020.

The trip will be led by Laurence Robb, Paul Nex, Judith Kinnaird, and Karl Hartmann, and hosted by mine geologists and personnel at each of the mines to be visited. Accommodation will be in lodges and hotels, and travel will be by bus, with numbers limited to 25. This is a unique opportunity to examine the spectacular mineral districts of south-western Africa in the context of the long-lived crustal evolution of the region.

The Centenary Regional Event immediately precedes the GSSA's 2020 Geocongress conference that is hosted this year, between June 29 and July 1, in Stellenbosch – participants may choose to travel directly from Kimberley to the Cape to take part in Geocongress 2020. Details

Please bring steel-toed boots or certified safety boots. Other PPI equipment (hard hats, safety glasses, gloves, high-visibility vest, etc.) will be provided at the visited sites when necessary.

Weather in June in Namibia and South Africa is mild (20-30°C) with cool to cold evenings (2-8°C), so bring a warm jacket for cooler days and evenings. Also, a wide-brimmed hat, sunglasses, sun protection as well as mosquito protection (for evenings) is recommended for all participants.
