54 THE NIEUWERUST SERIES 



The Nieuwerust beds cannot yet be correlated with 

 any other formation, though one is inclined to suspect 

 that intervening links will connect them with the little- 

 known quartzites first described by Wyley from the 

 country immediately south of the Orange Eiver in Little 

 Namaqualand, and mapped by him as " Table Mountain 

 Sandstone," l and subsequently coloured in as Witte- 

 berg beds by E. J. Dunn. 2 



It is possible that these beds represent part of the 

 nearly horizontal arenaceous rocks in German South- 

 West Africa and the Zwart Modder series of Gordonia, 

 but correlation with the rocks of Griqualand West will 

 be difficult.

 with the Nieuwerust series.
