Extract

The lavas which cap the Karroo beds of Southern Africa have general interest as indicating the eruptive activity prevailing at a time of complete quiescence in the European area. The sedimentaries immediately beneath them (Stormberg series) are of Rhætic or even Liassic age, so that the lavas themselves, which are many thousands of feet thick in the Drakensberg range, may confidently be ascribed to the Jurassic period.
