292 THE ENON BEDS 



deposited. In the country farther west there is corrobor- 

 ative evidence of this, as we shall see later. 



Fragments of wood with a charred appearance, very 

 different from the petrified wood in the Wood beds, oc- 

 cur frequently in the Enon beds, and up to the present 

 time these are almost the only organic remains known 

 from the typical Enon beds in the Uitenhage area. 



At Enon, which is situated in a kloof under the Zuur- 

 bergen, the conglomerate forms high hills which are 

 curiously carved into crags and caves by the action of 

 the weather, the rocks being harder in some places than 

 others. The conglomerate is white or red, but in this 

 neighbourhood there is no general occurrence of a lower 

 band of red rock and an upper layer of white as in 

 Willowmore. From Enon the conglomerates have been 

 followed eastwards to the Bushman's River ; but the 

 belt of ground occupied by them becomes narrower in 

 that direction, for they are let down along the Zuurberg 

 fault, the throw of which increases eastwards and brings 

 in the clays and shales above the conglomerates. At 

 Sand Flats a bore-hole sunk at a spot 1-J- miles south of 

 the fault penetrated 1,500 feet of sediments without 

 reaching the conglomerate. From Enon eastwards the 

 dip of the beds is southwards, away from the fault, at 

 various angles up to 20, but the dip decreases south- 

 wards. The south flank of Zuurberg west of Enon and 

 east of Bushman's River has not yet been surveyed geo- 

 logically, and the terminations of the fault and the re- 

 markable volcanic rocks along it (see p. 366) are not 

 known. The conglomerate in this area contains pebbles 

 of quartzite and quartz up to eight inches in length em-
