SOX PLATEAU. 223 



say which ground is formed of rock in situ, and which merely of debris ; 

 in fact one form so closely resembles the other that no hard line of 

 demarcation exists. Over this ground are scattered patches of the num- 

 mulitic limestone which have to a great extent undergone degradation 

 and yet retain much the appearance of being in situ. One tract north- 

 west of Sothi is covered by the triassic beds, generally much broken, 

 but in places actually i?i situ resting on the upper beds of the car- 

 boniferous limestone ; while some of the hills and all the deeper valleys 

 show the " speckled sandstone " exposed by denudation. Near Gogra 

 the underlying " purple sandstone " appears with patches of the " red 

 gypseous marl/^ all in a very confused condition, the nearest rock to the 

 marl being sometimes its proper associate, the purple sandstone, but 

 sometimes the nummulitic limestone or one of the other groups. This 

 confused and much disintegrated ground extends north-westward in and 

 along the valley of a stream which runs from near Nanga west of Jalar 

 into the larger gorge near Kavhad. Towards the upper part of the 

 stream, and between it and Nanga, nummulitic limestone in an almost 

 detrital state prevails; but the red sandstones, &c., of group No. 5 are 

 seen in the stream bed.

ous limestone forms hilly ground to the south, and 

 cliffs to the northward, of a little plain, which ends at a complicated and 

 deep clay khuddera to the eastward. There seems to be an east-and-west 

 . fault passing along the foot of the northern limestone cliffs, and exposing 

 some of the underlying speckled and reddish sandstones here and 

 there. To the north of these cliffs and rising obliquely on the north- 

 erly slope of their beds, a narrow (triassic) 

 Ceratite band is occasionally seen, succeeded by 

 the nummulitic limestone. The whole of the latter is present, dipping 



also northwards at 55" and overlaid by a long
