PAINKANDA SFXTIONS. 113 



red Crinoid limestone is thinner bedded, and is 

 White quartzite (8). . .... . , . 



partially alternating with white quartzite beds 



near the boundary. 



The latter division is exceedingly variable in thickness, from 350 

 feet in the Silakank sections, to 600 and 800 feet further south-east- 

 wards. It is generally a pure white sugar-grained quartzite, almost 

 resembling white marble in texture, and I found it in most localities 

 forming very thick massive beds, which become rather more flaggy 

 towards the top of the division. Both the Crinoid limestone and the 

 white quartzite show a great deal of local disturbance in the shape 

 of minor faults and jointing. 



I found several badly preserved fossil remains in the quartzite 

 but was not often lucky enough to be able to extract them from the 

 solid hard rock. On the weathered surfaces of the white quartzite 

 casts of Orthis sp., Orthoceras sp. are rather common. 



The best section in the Niti area, which shows the Crinoid lime- 



Marchauk pass best stone (7)> and the white quartzite (8), is perhaps 

 sect,on - the Marchauk one ; there the small glacier, over 



which the final ascent to the pass leads, passes through the upper car- 

 boniferous rocks. The sides of the glacier valley are composed of the 

 red Crinoid limestone (7), whereas the precipitous cone on the right 

 (south) side of the pass 19,518' high, consists of the white quartzite 

 (8). It is a most conspicuous, and I believe inaccessible peak, not un- 

 like the Matterhorn in general outline. The moraines of the small 

 Marchauk glacier are all composed of angular fragments of upper 

 carboniferous rocks, the red Crinoid limestone conspicuously showing 

 amongst the pure white quartzite. 



About two miles south of the Marchauk the Hoti peaks (18,457' and 



19,228') project their steep cliffs from amongst 



Hoti peaks. . . . 



a covering of eternal snow ; their highest 



ridges and peaks consist of upper carboniferous rocks, the densely 



red Crinoid-Yimestone (7) resting on the dark-coloured £Vtf/-limestone 



(6), and is capped by the white quartzite (8), the latter weathering 



a rusty brownish yellow.
