the trap-flows, as the limestone has been denuded away to the south of the 

 fault, owing to which the trap there rests directly on the shaley sand- 

 stones. Close to the line of fault the limestone dips to the north at 40°, but 

 in a very little distance (30 to 40 yards) the dip has decreased to 15°, and 

 continues decreasing rapidly till the beds are all but horizontal. The 

 shaley sandstone south of the fault lies horizontally. A couple of 

 hundred yards north of the fault the trap rests on the limestone, which 

 has not there been denuded. This fault seems not to extend westward 

 beyond the head of the bay-shaped valley where it occurs, for the 

 limestones on the west side of the bay rest on the shaley beds in undis- 

 turbed conformity. To the eastward the line of faulting extends several 

 miles, but everything is covered by thick regur till beyond the villages 

 of Dewapur and Katapur. About a mile to the eastward of the latter 

 village, the limestone boundary is again seen protruding above the sur- 

 face of the country and its dense covering of cotton soil. The dip of 

 the basset edge is again northerly, and varies from 30° — 35° near the 

 crossing of the Talikot-Sorapur road, to 75° — 85° south of Kalludu- 

 nuhalli. The same rapid decrease of dip to the northward is again 

 observable here from 30° at the basset edge to 2° or 3° only a few score 

 yards to the north. The limestone certainly appears to abut against 

 the gneissic rocks, but the contact was not seen anywhere owing to the 

 thick coating of superficial deposits just at the edge of the limestone 

 area. The gneissic rocks are coarse-grained, and have weathered so 

 greatly that no protrusions of them are seen anywhere near the lime- 

 stone boundary. Eastward of the spot where the extremely high dip of 

 the basset edge of the limestone before mentioned is met with, the fault 

 can no longer be traced owing to the great continuity of surface de- 

 posits. It evidently dies away gradually, for between Hebbal Khurd 

 (Khoord) and Bachimalli, where the boundary has again become un- 

 covered, it is a boundary of erosion, not of faulting. 



Except along the western side of the limestone basin from where 

 the Bhima river enters it, and where the limestone series is overlaid by 

 an upper series of red shales, the upper limestone beds, from near
