Late Precambrian glaciogenic sedimentary rocks in southern Africa: a compilation with definitions and correlations

Alfred Kröner, Kalervo Rankama

Open full text 37 citations

Abstract

Evidence of ancient glaciations is summarized, and the terminology dealing with glaciogenic and nonglaciogenic sedimentary rocks is discussed. The term tillite is used as a comprehensive genetic term for both continentally deposited and ice-rafted indurated tills. The glaciogenic origin of any rock called tillite must have been proved beyond doubt. The term mixtite is used for sedimentary rocks that resemble tillites but are of uncertain or unknown origin.
