Vol. 56.] THE GEOLOGY OP GILGIT. 359 



A dark grey schistose slaty rock, dipping about 75° north- 

 ward, and striking west by north and east by south. 



About 2 miles up the valley two beds of limestone, close 

 together, the southern being 50 and the northern 100 feet thick, 

 cross the valley with the same strike as the schistose slaty rocks. 

 I have three specimens. Of these one is a white crystalline lime- 

 stone ; another is a bluish-grey chert, with fine quartz-veins ; and 

 the third is a grey-and-white streaky limestone containing quartz. 



One mile farther on, near the village of Hatun, a third band of 

 limestone, 400 feet thick, with which thin schistose beds are 

 intercalated, crosses the valley, dipping vertically, and with the 

 same strike as the other beds. I have four specimens of this band. 

 They are all compact in structure, the first two and the last are 

 white, and the other bluish-grey. One of the specimens is slabby, 

 with silvery mica on the splitting surface. 



Capt. Roberts thinks that these three outcrops of limestone, which 

 he calls the Hatun Series, represent the Nilt-Hini Beds of the 

 Gilgit Valley. There also, it will be remembered, the beds are three 

 in number (p. 351). 



The Hatun Limestones are succeeded by a thinly -bedded calcif erous 

 slaty rock, with which is interbedded an altered ash. The ash 

 contains numerous fragments (large and small) of plagioclase-felspar. 



Between Hatun and Chatorkand, a distance of about 9 miles, a 

 bluish-grey micaceous slate, which reminds me very much of 

 some rocks of the Simla area, 1 occurs, sparsely interbedded with a 

 chloritic epidotic fissile rock that looks like a very fine ash.

 and Chatorkand. 



age • Chatorkand 



Capt. Roberts sends me a sketch (fig. 4) of an anticlinal fold 

 which is well seen on the west side of the valley, between Hatun 

 and Chatorkand. The centre of the fold is very distinctly marked. 



About 2 miles north of Chatorkand two beds of limestone, at 

 an interval of 1 or 2 miles one from the other, cross the valley with 

 approximately an east-and-west strike. They dip about 70° north- 

 ward, and the two hamlets, Pakor and Shenas, ' lie on or near 

 their strike/ The micaceous schists in which they lie are paler and 

 more finely laminated than those associated with the Hatun Series. 

 The schists and limestones are regularly bedded, and no contortion 

 has taken place. No granite-dykes are to be seen in this section. 

 The Pakor limestone is about 30 and the Shenas limestone about 

 100 feet thick.

 road below Balun.
