234 WYNNE : GEOLOGY OF THE SALT EANGE IN THE PUNJAB. 



northern side^ forming' the higher part of Sakesar mountain. Far to 

 the south, in one of the small tributary vallejss to the left of the 

 gorge, an isolated, faulted, and subsided fragment of these rocks occurs, 

 associated with some of the coal-shales beneath, and in junction 'with 

 a remnant of the overlying petroleum-bearing tertiary sandstones, the 

 manner of their exposure being singular, and the connexion between 

 their present position and their original mode of occurrence not easy to 

 trace. 



Of many faults in the glen the principal one runs down the left 



bank of the main stream, crossing it north of 

 Faults. ^ . . 



Amb, and obliquely ascending the opposite side 



of the glen. This fault appears to be a continuation of that at Jalar. 

 Another runs up the branch glen beneath Amb village, and there are 

 others besides. Two or three principal lines of land-slippage coincide 

 with the general run of the main glen, former cliffs having slipped 

 down the south face of the Sakesar mountain ; while nearer the mouth 

 of the glen, the number of these dislocations and the variety of their 

 directions give the whole mass of the rocks a most confused arrange- 

 ment. 



The hill to the east of the mouth of the gorge is capped by the 



Hill east of gorge carboniferous limestone, undulating or dipping 



™°^*^' northward. This limestone is surrounded by its 



own debris, below which the ''speckled sandstone,^'' " purple sandstone,''"' 



and " red marl " groups appear. Towards the gorge the two latter 



alternate along nearly north and south lines of slippage, none of the 



groups being entirely exposed. On the opposite side of the glen^s 



mouth, gently rising ground is covered with

limestone iragments, but lurtuer up portions ot 



the speckled sandstone and carboniferous limestone appear, none of 



which, perhaps, are in their proper situations. High up on this ground a 



narrow shifted band of the salt-marl crosses out from Amb glen, and 



runs along to the west, partly occupying high ground and partly the 



first depression behind the outer hills. It is associated with numerous
