'n Ondersoek van die puinafsettings in die noordelike knakpunt van die Daspoortrand naby Pretoria. (Investigation of deposits in the northern knickpoint of the Daspoort ridge near Pretoria)

Description :
In an effort to obtain more information about the circumstances of the formation of deposits of colluvial material, which are a common occurence in the Pretoria vicinity, profile descriptions, field surveys, as well as physical and chemical laboratory analysis were made of the exposed gravel deposits at the Daspoort ridge tunnel. From this investigation the tentative conclusion was made that there appeared to be two main periods of debris and one of sand deposition in the knickpoint and on the pediment of the Daspoort ridge which possibly date respectively from the last two Pleistocene pluvials and a Holocene pluvial.
