18 WAAGEN — WYNNE : GEOLOGY OF MOUNT SfEBAN. 



The series marked a is mucli disturbed and confused by slippage 

 of the nummuUtie and some of the underlying beds downwards on the 

 hill slopes. It is interrupted by a fracture beyond which the Jurassic 

 and cretaceous beds /3 again underlie the nummulitic rocks. Another 

 disturbance allows a small quantity of dolomite just to reach the surface, 

 and then some soft white sandstone occurs at the base of the nummu- 

 litic limestone y which forms this portion of the crest of the hill.
