A ca. 200Ma hiatus between the Lower and Upper Transvaal Groups of southern Africa: SHRIMP U–Pb detrital zircon evidence from the Segwagwa Group, Botswana: Implications for Palaeoproterozoic glaciations
(Elsevier B.V. www.elsevier.com/locate/epsl, 2006)
The Segwagwa Group of southeastern Botswana, a correlate of the Pretoria Group of the Transvaal Supergroup of South Africa,
consists of a major sequence of siliciclastic sedimentary rocks, minor carbonates and basaltic ...
