Geochronological evidence for tectonically driven brine migration during the Early Proterozoic Kheis Orogeny of southern Africa

Michael J. Duane; F. Johan Kruger

The 2.1–1.9 Ga Kheis orogeny on tne western margin of the Kaapvaal Craton of Southern Africa induced regional heating, tilting and extensive fluid flow which isotopically reset and altered rocks and minerals of older Proterozoic formations and parts of the Archean cratonic basement. This tectonic event is recognised in the Ar, Rb-Sr, Pb-Pb and U-Pb (zircon) geochronological and palaeomagnetic studies on the Transvaal and underlying basement rocks.
