 Unconformity of trap hasin, covered up by the Deccan trap. The un- 



and Bhima limestones. ^ c -j. i, j. j.ij^ i •••■ 



contormity between the two rock series is less 



distinct here than further north, but it can be traced in the shape of 



overlap on limestone beds occupying- very different horizons. The highly 



disturbed and broken beds of limestone between Parwattabad and 



Deyrun Tegganur are also overlaid by level flows of trap. 



West of the Bhima very nearly the whole area up to the scarp of the 

 trap boundary north and north-west of Gogi is occupied by the lime- 

 stones which mostly lie horizontally or roll about at low angles, 

 except along the southern boundary of the basin, where their relations 

 are much complicated by great disturbances of the strata, which are 

 due both to faulting and crushing, as will be described in detail 

 further on. 



Disturbed and faulted honndary at Gogi. — For a distance of some 

 twenty -five miles the boundary of the Bhima basin (to the south of the 

 old town of Gogi) runs generally in an east to west direction, and, for the 

 greater part of that distance, the lowest beds which there occur are 

 seen in a vertical position abutting against the gneiss. The western end 

 of this line is so obscured by superficial deposits that Mr. King found it 

 very difficult to lay down any definite boundary between the gneissie 

 rocks and the Bhima beds, but wherever he hit upon the limestone, it was 

 vertical or at very high angles. Actual contact of the two rock series 

 was not seen westward from Darshinapur^ towards Veur (Veyoor), but 

 near the latter place some blue thick-bedded limestones, vertically up- 

 Coarse limestone brec ^^^^^^^^ ^^^^ extremely coarse breccia-structure, and

contain beds of chert. There are here two bands of blue limestones 

 enclosing thinner bands of grey silicious beds full of chert nodules and
