54 WYNNE '. GEOLOGY OF THE SALT RANGE IN THE PUNJAB. 



A long fault stretches close by the south-eastern foot of Mount Tilla, 



bringing- the lowest rocks there exposed against 

 Tilla faults. .111^1 



steeply inclined or vertical beds or the tertiary 



sandstone and clay series : three minor dislocations parallel to the main 

 one lie between the unbroken uniclinal of the mountain and the master- 

 fault, The displacement here must be large, but cannot be exactly 

 estimated, because of the positions of the rocks. The fault is lost in the 

 sandy gorge of the Biinhar river at Pind Sevika, 



North of JaMlpur an extensive and most complicated amount of 



faulting has taken place, bringing the groups at 

 Jalalpur faults. .... 



each end of the series into junction, a large 



branch fracture extending along the western base of Chambal mountain 



(east) apparently to join the Tilla fault. 



One of the most considerable lines of faulted dislocation in the whole 



district coincides very much with the direction of 

 Karangu and Diljaba fault. ^ -n , ,, .^ . ,. 



the Bakrala ridge, sometimes lying at one side, 



sometimes at the other, the line being certainly far from straight, and the 

 whole dislocation appearing like an extended combination of shorter 

 fractures. One of the results of this zone of faulting is the exposure of 

 a mass of nummulitic limestone on the sandstone and clay ridge near 

 Domeli; another is the way in which this limestone disappears at 

 Ghoragali pass, among the overlying beds, the same or a parallel fault 

 occurring here on the north-west side of the ridge. The escarpment of 

 Diljaba mountain is also connected with this line of fracture, which ap- 

 pears to be itself displaced by a cross-fault at the western end of that hill. 

 In the neighbourhood of Chel hill much contortion and great dislocation 

 occurs on both sides of the ridge, but most towards the Potwar country. 

 Whether the fracture is here again connected with the main line or 

 not is obscure, but the fault with its original direction reappears on 

 the north-west flank of Karangli hill. Here it turns into the Choya- 

 Saidan-Shah valley, bringing the tertiary sandstones against the salt- 

 marl. From this valley the fracture bends down the deep Gamthalla
