West of Saiduwali recess. 



Paniala. 



Westwards from the Saiduwali recess the Khasor range declines in 

 elevation, with the appearance of a much com- 

 pressed and crumpled declining anticlinal axis, 

 covered over by the Jurassic rocks and trias beds mentioned in the last 

 section, the many deep ravines exposing the lowest part of these rocks, 

 and one towards the west not only the carboniferous but some of the red 

 boulder beds below. 



In the neighbourhood of Paniala the rocks appear to have suffered 

 much from compression and fracture, a detached 

 mass of the Siwalik tertiaries being forced into 

 faulted contact with the Jurassic rocks, in a ravine due south of the 

 village ; and from near this place to the eastward the boundary between 

 the Jurassic and tertiary beds appears to be a fault, the drab and olive 

 clays of the latter formation resting in places against inverted beds of 

 the variegated Jurassic group. The contact was originally one of un- 

 conformable overlap no doubt, but subsequent disturbance seems also to 

 have been accompanied by displacement. 



The tertiary beds are here chiefly soft gray thick-bedded, and in parts 

 pebbly, sandstones with subordinate bands of clay, and the Indus pebbles
