The sides of the gorge expose high cHff-seetions from the nummulitic 



limestone downwards to the red salt-marl, which

runs up the glen for a distance of nearly five miles. 

 It is evidently the horizontal disposition of the strata that leads to the 

 exposure of the salt-marl, so far up this and other glens intersecting 

 the plateau-country, which is itself a result of the horizontality of the 

 bedding between the southern escarpment and the line along which the 

 rocks assume a northerly dip. 



As noticed by Dr. Fleming and others, with regard to this gorge, 



the strata have a low dip from the valley towards 

 Anticlinal. .^ 



the east and west; and, as Dr. Warth has ob- 

 served, there are masses of brick-red gypseous marl on the east side 

 of the glen, near the mines, which are unrepresented at its western side. 

 This can hardly be accounted for except by slipping or by supposed len- 

 ticular irregularity in the stratification of the upper part of the marl. 

 Disappearance of the salt beds by solution should have caused a smaller 

 development of the whole group on the eastern side of the glen, and 

 faulting would not be tenable on the presumption that the beds of salt 

 and gypsum retain the arrangement attributed to them, at Khewra and 

 elsewhere, by Dr. Warth. There is, however, another and more feasible 



T , ,. ,. explanation of the difiieulty ; for, to the westward 



JUancl-slip, concealing ^ "^ 



part of section. of the mines, a great land-slip has taken place ; a 



tract of the nummulitic limestone, two and a half miles long, having 

 subsided from its continuation with that of the cliffs of Mavjhang. 

 In consequence of this dislocation, which can hardly be supposed limited 

 only to the nummulitic limestones, the underlying strata appear to 

 have been pushed out over the marl, so as to conceal the portion of the 

 latter which is really uppermost in the vicinity of the mines ; and the 

 salt beds of Sardi, if on nearly the same horizon as those of Khewra and 

 south of Yadala, would seem to have above them a local development 

 of the gypseous red marl unknown in those localities. 



As is often the case with regard to slipped masses along the escarp- 

 ment, that under Marjhang, although it is broken and confused, and
