152 MIDDLEMISS: GEOLOGY OF HAZARA AND BLACK MOUNTAIN. 



northerly direction, the section is entirely in the Trias limestone, 

 shewing bare scarped edges to the climber, which strike along the 

 general direction of the ridge towards the ,c M M of Mohree Budbhain. 

 At the top of the hill the beds flatten out with a few minor folds. 

 A little way below the summit, along the spur going W. by N., traces 

 of Gieumal sandstone and Grey limestone appear, but the rest of the 

 section can be better followed in the stream-bed which goes from 

 the gap north of Naruh police station towards Dhunuk. Along that 

 line the Spiti shales are feebly exposed, lying in a slightly inverted 

 position against the Trias, which is here full of indistinct remains of 

 shells. The Spiti shales are followed by Gieumal sandstone, then by 

 the Cretaceous band, and then by Grey limestone. The Grey lime- 

 stone continues in force down to the point due north of the first "h" 

 of Kurchh in the stream -bed. There must then intervene a fault, for 

 the next rock is a thin strip of slates followed by Trias limestone once 

 more. Whilst the outcrop of the latter passes round to the north-east 

 to join up with the Trias of Mohar hill, the thin band of slates passes 

 by a series of gaps on the hill-spurs to join up with the slates of 

 Deewal. Throughout this traverse the strike has gradually been 

 turning round from E.N.E. to N.N.E. Trias limestone, so far as 

 exposures allow one to judge, continues to the Nalan river ; but the 

 recent gravels of that stream conceal its relation to the slates beyond. 

 The following rough sketch section through the top of the hill, north 

 of Naruh in a W.N.W. direction, will generally indicate the structure 

 of this small outlier of the younger formations upon the slates : —
