Vol. 56.] THE GEOLOGY OF GILGIT. 369 



With regard to the Carbo-Triassic Series, he had formed the con- 

 clusion that these rocks were crushed up between the folds of the 

 granite and the metamorphic rocks, occupying distinct long, narrow 

 troughs, or elliptical basins. Thus a great development of this 

 series is to be seen south of Scardo extending to Shigar ; in the 

 gorges running from Scardo up to the Deosai plains, magnificent 

 sections are exposed of the great folds into which these rocks have 

 been thrown. This southern band can be followed eastward over the 

 Tusserpola for many miles, and westward across the Indus to the 

 Tormick Valley and the Stok La. A range of granite and the 

 older rocks comes in on the north, but at the end of the Biafo 

 Glacier the same section is repeated, and another belt of the Carbo- 

 Triassic can be followed eastward to the Masherbrum Range and 

 westward along the Braldu Valley to the Chogo Loongma Glacier 

 near Chutrun and Arundo. The high ridge between the last-named 

 glacier and the Hispar is in great part Carbo-Triassic. A third 

 distinct and more northerly band of stratified rocks (but no massive 

 limestone) is met with at the upper sources of the Palma Glacier 

 on its northern side. This lies west of the Mustakh Pass; it was 

 seen to extend westward, and very probably joins the stratified 

 rocks north of the Hispar Glacier in Hunza Nagar. The section 

 on the Baltoro Glacier reminded him in its composition of the rocks 

 met with on the Pir Panjal. 



The President and Mr. E,. D. Oldham also spoke, and the Author
