The Devonian-Carboniferous boundary in South Africa and the age of the earliest episode of the Dwyka glaciation: New palynological result

Abstract

Miospores, fish fauna and probably megaflora concur to assign a Lower Carboniferous age to the Waaipoort Formation (Witteberg Group), thus supporting the suggestion that the Devonian-Carboniferous boundary in South-Africa lies at the level of the conspicuous lithological reversal represented by the Witpoort/Kweekvlei contact. All the evidence displayed indicates overriding of the Dwyka glaciers relatively shortly after deposition of the uppermost Witteberg sediments.
