Eastward of Khura the uummulitic limestoues soon close in round 

 Nummiilitic east o£ ^he end of the small plain. Northwards, they

 are not only bent into a sharp curve, but also faulted, some of their 

 underlying shaly beds appearing in the side of the road at the steep 

 descent leading to the Sodhi valley and bungalow. 



The post-tertiary deposits of the upper part of this Sodhi valley have 



Post-tertiary conglo- ^®®° already alluded to; they are well seen near the 



'^^^^*®- junction of the road from Khilra with the Sodhi 



and Sakesar road ; where drab clay and coarse brown, soft, sandstone, 



with limestone pebbles, lying on the south slope of a nummulitic 



limestone hill, dip at so high an angle as 20" to 

 Naoshera.

Westwards from Khura the upper carboniferous beds and overlying 



trias continue along the indented boundarv of

the nummulitic rocks, a long narrow promontory 



of which juts out to the east-by-south for about four miles from their 



main mass; small outlying patches also occur. The direction of this 



extension of the newer limestone is almost exactly parallel to a laro'e 



fault running from near Katwahi to the westward, and bringing the 



carboniferous, the nummulitic, and tertiary sandstone groups into 



abnormal junction. 



From this fault another is supposed to start in a south-westerly 



direction through some undulating or flat ground

till it reaches the Kavhad gorge, down which it 

 passes out towards the southern plains. In the flat ground, of course, 

 this fault is concealed, but nearer to the gorge nummulitic and carboni- 

 ferous rocks are brought against everything lower than the latter. To 

 the right of this Kavhad ravine the ground is hilly and covered with 

 broken masses of carboniferous limestone and the " purple sandstone " is 

 seen overlying a large exposure of the salt-marl. On the left-hand side
