164 MIDDLEMISS : GEOLOGY OF HAZARA AND BLACK MOUNTAIN. 



from which up to the top of the Bagh-Maira hill the ordinary ascend- 

 ing series of formations is unbroken, although the outcrops wind about 

 and return upon themselves in a rather complicated way, due, on the 

 one hand, to the folding of the rocks, and on the other to the three 

 side-spurs and intervening streams which travel north-east, respect- 

 ively, from the three summits of the hill. The section and map 

 should suffice to make this structure comprehensible without further 

 remarks. 



The hill-spurs south-west of Bagh, across which the main section 

 (horizontal section No. 1) takes its way, only consist of slates with a 

 small synclinal fold of Trias capping them, a direct continuation of 

 the same rock of the Bagh hill. 



From the southern end of the Bagh-Maira outlier, where there 

 is a marked gap in the Slate series, the ascent

with a gentle inclination as a rule, though a few 



steeper slopes are to be met with. Forest begins almost as soon as the 

 gap is passed at about 5,700 feet, and the whole of the rest of the way 

 into the colder air zone in which the top of Taumi, 8,025 feet, lies is 

 also through forest which can be seen to spread away, covering all 

 the more elevated hill-tops in the direction of Bara Gali. The pre- 

 vailing rock during the ascent is slate, but near the final peak there 

 is a small patch of Trias limestone perched on the summit of a neigh- 

 bouring peak. Tj.umi also owes its steep craggy summit to the pre- 

 sence in the Slate series of quartzite beds of a hard dark purple-grey 

 colour, and in thicker and stronger beds than ordinarily occur with 

 the slates. These same quartzites extend north-easterly and give to 

 Mian-Jani-ki-choki its peculiarly elevated summit of 9,793 feet. 



The most important interruption of the slates in the ascent up the 

 Taumi spur is, however, a great faulted mass of the historical rocks 

 from Trias to Nummulitic, the outcrop being two-thirds of a mile 

 wide. The dip of the whole mass is north-west at angles of 50 — 6o°. 

 In the Taumi direction it rests upon the slates in normal order, the 

 base of the Trias consisting of the usual quartzites, and presenting in
