Rhyolitic ignimbrites of the Cape Granite suite, southwestern Cape province, South Africa

Scheepers R. ; Nortje A.N. (2000)


Based on textural and geochemical evidence, the existence of Late Precambrian rhyolitic volcanism related to the Cape Granite Suite is illustrated. Recrystallised rhyolitic ignimbrites represent the volcanic phase of a subvolcanic to volcanic sequence composed of rhyodacite to rhyolitic magma. Textural features including fiamme, pumice fragments and glass shards provide unequivocal evidence for the volcanic origin of these rocks. © 2001 Published by Elsevier Science Limited.
