some 200 feet in thickness, are very soft and friable, and consequently 

 occupy the bottom of a valley. The basin is incomplete, being- faulted 

 in an east-and-westerly direction against a narrow strip of the BelleropJion 

 beds of the carboniferous limestone, which forms an escarpment overlaid 

 by the triassic and nummulitic beds. 



This locality was visited by Dr. Waagen, whose notes on the detailed 

 section are given below : —

Northwards from this the nummulitic limestones undulate with a good 

 deal of northerly dip into the Son Sakesar Kahar basin. To the east- 

 ward they are more violently contorted, and in the hills behind Naoshera 

 they are covered by unconformable detrital beds (similar to those of the 

 head of the Sodhi valley) dipping northwards at low angles generally of 

 about 10°. 



Westwards of Jalar the carboniferous limestone cliffs which
