Abstract: | 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 faimme, pumice fragments and glass shards provide unquivocal evidence for the volcanic origin of these rocks. |
