Fauna and Stratigraphy of the Stormberg Series 447 



Pot River to Tent Kop in Maclear. This shows predominating purple 

 and red shales, mudstones and soft sandstones often of remarkably 

 brilliant colouring which bleach on exposure. Coarse grits and 

 occasionally pebbly sandstone occur at the base, and not uncommonly 

 there are found boulders of quartzite like those of the Molteno Beds. 

 The most prominent sandstones are usually white in colour, and in 

 places contain nodules of iron pyrites or marcasite. Many of the 

 sandstones when fresh are red: they are commonly full of porous 

 patches which represent spots originally rich in calcareous material. 

 Clay-pellet conglomerates are not uncommon at the base of certain 

 sandstones. Fossil wood is occasionally seen. Vertebrate fossils are scarce. 

 In Mount Currie the thickness is only 400 feet. The beds, as else-

Natal. At Hlatikulu Hill the Red Beds have a thickness of 430 feet 

 resting on the Molteno Beds. Shales overlie the top white coarse 

 grit of the Molteno Beds, and contain one or two gritty bands. They 

 are succeeded by white and dark red. sandstone with red, purple and 

 blue mudstones and soft sandstones; these by dark purple mudstones. 

 Then comes a massive medium-grained sandstone with grit at the 

 base, and between it and the Cave Sandstone are reddish shales. 



Further north, at Bezuidenhout's Pass on the O.F.S. border the 

 thickness has diminished to 400 ft. The formation rests directly on 

 purple niudstonps of the Upper Beaufort Beds and has at its base a 

 bed of gritty and pebbly sandstone which, in its lower portion t has 

 quartz-pebbles up to ',._, an inch in diameter as well as pellets of shale 

 and some sandstone fragments. The mass of the Red Beds is made
