Records of the Geological Survey of India. 
At Kotgarh the general dip is low northerly, whilst at Kapu, the gneiss dips north-11 -west. 
These facts seem to indicate an anticlinal hend from the crest of the Hattu-Kot ridge down 
to the Satlej. If this is not the case, there must be a fault, for that the gneiss seen along 
the left bank of the Satlej, between Kapu and the Nogli River, is a continuation of the 
gneiss seen on the crest of the Hattu-Kot ridge, I see no reason to doubt. 
VI.— Sxjngei—Ramptje—Sarhan—Sangxa. 
To get over the ground I must now be very brief and bald. Prom the outcrop of the 
gneiss 4 or 5 miles beyond Kot, there is nothing to record as far as Sungri. The rocks 
are micaceous and silicious schists. Elevation of Sungri 8,675 feet. Dip south-east. The 
Hindustan and Tibet road between this and Sarhan having fallen into decay, the road fiom 
Sungri plunges down into a very deep ravine, at the bottom of which the gneiss shows itself 
again. True dip about south-east. Beyond Dalog* the gneiss is again reached, and it con¬ 
tinues for a long way. It gives place to mica-schists, but at Bali (Bari of the map), elevation 
8,000 feet, the gneiss again crops out. Dip, eliminating local variations, south-east, all the 
way. The “ central ” gneiss continues to show down the descent to the Satlej as fat as Kamsu. 
Dip, where road strikes Satlej, south-ll°-west. Prom this point there is trap of the Mandi 
type for about 2 miles (the trap shows best in the bed of the river which I crossed and 
recrossed frequently on massetks). Schists resembling the Inira-Krol series show after 
this, and then the trap again. The strong quartz beds are burst asunder and twisted about 
by the trap in a wonderful manner. Prom Rampur (elevation 3,600 feet), the road rises to 
Gaora (8 miles, elevation 6,520 feet). Dip usually flat. Quartz-rock predominates for a 
long way ; there are also micaceous and hornblendic schists. Hear Gaora we have chloritic 
and talcose schists, and then gneiss, the folise of which are much crumpled. It only shows 
its small porphyritio crystals at right angles to the foliation. 
To Sarhan, 11 miles, elevation of road 6,775 feet, the dip is rather low and north-ll°-east 
most of the way, but veering round to north-north-west at Sarhan; rocks, mica-schists and 
gneiss, hornblendic, chloritic, and talcose schists. Near Sarhan crumpled gneiss. The rocks 
are more than once repeated owing to the windings of the road in and out of the side 
valleys. This is a common feature in the sections exposed along the Satlej valley. 
Sarhan to Taranda.t 14 miles; elevation of Taranda, 7,200 feet. Dip at first north-lo¬ 
west, afterwards north-north-west, with an occasional waver to north-west-ll°-north. Near 
Taranda there are indications of great disturbance, the dip changes to north-north-west, then 
to west-south-west, then to west, then suddenly to south, with a high dip that soon becomes 
vertical. Then we come on three or four strong bands of hornblende-schists. Pour miles 
beyond Sarhan the gneiss passes into a fine-grained whitish granite (only the gneiss altered) 
and then back into gneiss. Prom this point the “central” gneiss passes backwards and for¬ 
wards from a porphyritic gneiss into a porphyritic and highly granitoid rock. Small dykes 
of the albite granite now become more and more frequent. Near Pauuda there are beds 
of hornblende-schist turned up perpendicularly with the gneiss, which hard bye dips 37° 
to south-west. After this the dip was nortk-west-ll°-north, north-ll°-west, north-north-west, 
and finally settled down into north. 
From Wangtu, owing to the complication arising from the frequent eruption of the 
granite the gneiss runs into great masses-of granitoid texture, and I could not make out 
the direction of the dip for many miles; where the bedding of the gneiss could be discovered, 
it dipped north-west-ll°-west, further on, the dip appeared to he north-east-ll°-north. 
* Either Naora of the map or a village close to Naora. 
p This is, I think, about a mile to the east of Nanaspar of the map, just to east of Station, 7,362 feet.
