    • The Paleoarchean Buffalo River komatiites: Progressive melting of a single large mantle plume beneath the growing Kaapvaal craton 

      Netshidzivhe, Thendo; Tappe, Sebastian; Wilson, Allan H.; Ishikawa, Akira; Viljoen, Fanus (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-06-01)
      Several Archean granitoid-greenstone terranes are exposed on the southeastern Kaapvaal craton in South Africa, but they received little scientific attention compared to the archetypal greenstone belt successions of the Barberton Mountain Land at the eastern craton margin. This study reports on a detailed field and geochemical survey of the Buffalo River Greenstone Belt at the southern Kaapvaal craton ...

    • Redox state of the Dharwar craton root as inferred from eclogite and peridotite sourced mantle cargo, with implications for kimberlite and lamproite magma formation 

      Shaikh, Azhar M.; Bussweiler, Yannick; Viljoen, Fanus; Bolhar, Robert; Ravi, S.; Hezel, Dominik C.; Ueckermann, Henriëtte; Tappe, Sebastian (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-11-16)
      Despite over 400 occurrences of kimberlites and related rocks in India, mantle-derived xenoliths are known only from a few occurrences. This paucity of mantle-derived xenoliths in Indian kimberlites has hampered investigations of the subcontinental lithospheric mantle (SCLM). Using a valuable selection of the rare xenolith inventory, we here report Fe<sup>3+</sup>/ΣFe measurements for garnets using ...
