siliceous : a short way beyond this in the same line, granitic roclr shows 

 a^ain, hut only for 50 or 60 yards, being succeeded by the rock-breccia, 

 and red sandstone. What most gives the idea of a decided fault of some 

 magnitude is the unusually steady and high dip of some of the more regular 

 strata along this belt, as just west of Heerapore, well bedded red sand- 

 stone dips at 80° to west, and the same along the hills by Benaida. If 

 the entire horizontal displacement of the boundary (some 15 miles) were 

 attributable to faulting, it would necessitate an enormous throw, or else 

 prove that the Bijawur rocks are of no great thickness, and the granite 

 surface irregular and at moderate depth from the present surface ; thus, at 

 Syntpa the decided scarp to the north may be said to end in a hill of granite 

 capped by the breccia ; and at Piperia, four miles nearly due south, there 

 is a similar junction ; and so at several places along the line, this breccia 

 shows as a bottom-rock. 



As to the nature of the cause of the peculiarly irregular disturbance 



„ of these strata, I can only offer conjectures : it

diti011 - seemed to me impossible that any modification 



by passive causes could so complicate the result of any single, general 

 contorting force. The centres of action were probably more local, 

 and one would naturally look to the trap rocks which so abound, for 

 a clue to the problem ; they certainly predominate along the north 

 side of the area, but are also found largely developed close to the 

 south boundary as in the valley of Chopra, and about Heerapore. 

 Though I did not see any case of intrusive contact, I believe them to be 

 of that class.
