  • Description: The Grunehogna Craton (GC, East Antarctica) is interpreted as part of the Archaean Kaapvaal Craton of southern Africa prior to Gondwana breakup. The basement of the GC is exposed only within a small area comprising the dominantly leucocratic Annandagstoppane (ADT) S-type granite. The granite (and hence the craton) has been dated previously only by Rb-Sr and Pb-Pb mica and whole-rock methods. Here, the crystallization age of the granite is determined to be 3067 ± 8 Ma by U-Pb dating of zircon. This age is coeval with that of granitoids and volcanic rocks in the Swaziland and Witwatersrand blocks of the Kaapvaal Craton.
