180 BLANFORD : GEOLOGY OF WESTERN SIND. 



distance up the Khar Nai within the line of the scarp, of which the 

 upper 500 feet consist of Gaj beds, aud only the lower 150 feet of 

 Nari rocks. The uppermost Nari beds here consist of a rather thick 

 band of very coarse grit, almost a conglomerate ; below this are soft 

 brown or grey sandstones, some beds being characteristically variegated 

 with white and purple, and containing ferruginous concretions. In the 

 soft sandstones below, one band contains oysters of a species somewhat 

 resembling 0. flemingi. 



The whole 500 feet of Gaj beds here consist of limestones, chiefly 

 light-coloured. The beds are well exposed at the point north of the 

 Khar ravine ; they are not very fossiliferous, but a band of Orbitoides 

 occurs. 



South of the Khar Nai the Gaj beds have a low southerly dip, 

 the plateau sinks down, the scarp disappears, and the Gaj boundary runs 

 to the south-west and approaches the Habb. On the Shor Wari Nai, 

 about 5 miles south of the Khar, the lowest Gaj beds are thinly bedded 

 calcareous sandstones of a pale colour, sometimes containing valves of 

 Balani, and in places Oysters, Spondglus, and Clypeader. In another spot 

 in the immediate neighbourhood, a bed just above the base abounds in 

 Ostrea mtdticostata. 



From Lohari Lang, where the caravan road up the Habb valley 

 crosses the river, the boundary of the Gaj and 

 Nari beds runs nearly due south to Mugger 

 Peer. The beds near the boundary in both groups are fairly seen, 

 the harder bands forming low ridges parallel to the boundary, whilst 

 the softer intervening strata are frequently exposed in the stream 

 beds and ravines between the ridges. This is especially the case on the 

 Hatari stream close to Lohari Lang Thana. Here the general dip of the 

 Nari beds is between 25° and 35° to east by a little south, the direction 

 of dip in the Gaj beds being the same, but the angle diminishing to the 

 eastward. 



The Lohari Lang Thana is 3 miles south of the spot where he name 

 is marked on the inch map, and nearly due west of Mio Trigonometrical
