126 MIDDLEMISS: GEOLOGY OF HAZARA AND BLACK MOUNTAIN. 



is nearly impossible. We shall, however, be safe in concluding that 

 the horizontal compression which the rocks have sustained here is 

 even more intense than that which the Sirban area sustained. 



The Trias band which lies next to the schists in the last section 

 Section near Dubbun. is continued ^ross the hill spurs to near Hazira, 

 when it skirts the south-east side of the Icher 

 (another stream of the same name as at Turnawaee), leaving the 

 schists occupying the other side. Thus the great boundary fault here 

 coincides with the flat and open stream-bed, which is the common 

 high-way between the lower country of the Mansehruh plain and 

 the high level valley of Dubbun. The long straight reach along 

 which the fault passes is monotonous and bare, save for a few elder 

 groves at intervals in the shingly bed. After a little over a mile the 

 fault leaves the stream-bed and passes along the north-west side of 

 valley for some way, eventually returning to the middle of the high 

 valley of Dubbun. Between the latter and the lower reaches lies a 

 steep and weary climb up the narrowed gorge in the Trias limestone 

 band east of the fault. This band continues diagonally across the 

 Dubbun valley and occupies the steep western slopes of Phoot hill 

 (6,654 ft.), whilst the boundary fault is indicated by a marked gap or 

 pass at the head of the Dubbun glen where the Icher drainage is 

 parted from the Rutwala drainage. 



The country between Sichar and Phoot trigonometrical points 

 was difficult of access at the time of our visit ; the sky was threaten- 

 ing snow, and had we lingered among these high valleys we might 

 have been weather-bound for a month or more. Consequently the 

 actual details of the continuation of the bands of the Infra-Trias and 

 Trias from the Turnawaee glen in this direction, and their dying out 

 or confluence, as the case may be, was not followed out by us. Hira 

 Lai, however, crossed from Turnawaee to Dubbun via Lagal bun and 

 was able to mark out two separate folds of Trias limestone, felsite 

 and Infra-Trias, whilst Edwards followed an apparently very thick 

 outcrop of the felsite along the ridge near Phoot, and subsequently 

 the cliffs at the head of the Booee stream under Phoot were shewn
