44 WYNNE : TRANS-INDUS EXTENSION OF THE PUNJAB SALT RANGE. 



A part of the field map is annexed (at this page), from which some of 

 the positions of the rocks will be seen more plainly than in the smaller 

 scale map with this Memoir. 



Section II. — The Chichali range and mountains to the north. 



The Chichali range extends from the dislocated hills of Kalabagh to 

 the westward, with a frontage often nearer 4,000 than 3,000 feet above the 

 plains, and chiefly occupied by the outcrop of the mesozoic and eocene 

 rocks. 



In the recess north of Kalabagh the first beds seen in the low hills at 



Eecess north of Kdla- foot o£ tne scar P ma y be 70 ° or 800 feet of tllick 

 b ^gh* Siwalik sandstones and conglomerate let down and 



crushed against the base of the higher hills to the north and east. 

 In the former direction some older looking purplish tertiary beds with 

 redder clays intervene, close to the fault, on the further side of 

 which rises part of a large anticlinal curve composed of the carboniferous, 

 trias, and eocene beds of these mountains. The white nummulitic lime- 

 stone and its soft underlying zone make a high double peak to the east, 

 over the Lun valley, the beds cropping steeply in the opposite direction. 

 Their basset edge then descends into the valley to the north, rising again 

 slowly to the Turgegarh summit (4,425 feet) on the western side of the 

 recess. By this arrangement part of the crest of the ridge is formed of 

 the limestone and variegated series of the Jurassic group, the latter from 

 its softness being cut into high cliffs, making ground very difficult to 

 traverse. The Jurassic ^rocks, particularly the variegated parts, are 

 largely developed here. The triassic beds are mostly exposed in vertical 

 cliffs, and the harder carboniferous limestones form a high- bench inter- 

 sected by very deep ravines. The axis of the anticlinal once formed by 

 the latter formation and succeeding beds plunges downwards at a steep 

 angle, passing west directly under Turgegarh summit. 



The carboniferous rocks are as usual strong gray limestones, and
