beds, but it is cnieny remarkable tor its low angle t 



it underlies to the eastward at a slope of only 40° from the horizon. 



On the Kenji Nai the Gaj beds come in at the foot of the first high 

 Sections of Kenji range. They dip at a very high angle to the east- 

 ward, like the overlying Manchhar beds, and their 

 outcrop is consequently narrow. They appear to be not more than 600 

 or 700 feet thick, much thinner than they are a little further south, — 

 an appearance due, perhaps, in part to compression caused by disturbance, 

 but there is very possibly a thinning out also. Towards the top more 

 than one bed of white gypsum is seen in the Gaj group, associated with 

 deep red and olive shales containing Corbula trigonalis, Tellina subdonaci- 

 alis, and a Turritella. These beds appear well developed, but the lower 

 portion of the group, beneath a conspicuous hard limestone band with 

 echinodermata and corals, does not appear more than half the thickness ; 

 it is in the Sita Nai, 6 miles further south. 



The Nari sandstones have a lower dip than the Gaj, and after some 

 distance the former roll over again and dip westward. Two bands of 

 brown limestone with Nummulites sublavigata, JV. garansensis and Orbitoides 

 pajayracea are seen at the anticlinal, each 3 or 4 feet thick, and separated 

 by 300 or 400 feet of sandstones from the more massive brown lime- 

 stones at the base of the Nari group. Just beyond the anticlinal is the 

 fault at Lakha-jo-Kandi already mentioned, at a spot where a stream 

 joins from the south. Beyond the fault the Kenji runs from the north, 

 and as the throw is here to the westward, higher Nari beds come in 

 dipping to the south. The stream cuts through Nari beds as far as 

 Chushang, where the Khirthar limestone crops out, and the Kenji has 

 cut a gorge through the limestone. Part of this gorge is occupied by a 

 deep pool of water known as Chushang Dhandh. 



One of the most interesting points in the Kenji section is the occur- 

 rence of bands of fossiliferous limestone in the Nari group at an eleva- 

 tion of 300 or 400 feet above the usual beds at the base of the group.
