WYNNE : GEOLOGY OF THE SALT RANGE IN THE PUNJAB. 



to an elevation of nearly 1,500 feet, and is singularly placed, an 

 enormous slip or fault having allowed the mass of a whole group of 

 hills, formed of the overlying strata, to subside so much below the level 

 of the marl, on the crest of the ridge, that, either from subsequent 

 atmospheric degradation, or from original displace- 

 ment, the marl for a short distance absolutely 

 overlies the magnesian group.

It seems most likely that the salt-marl was left standing as a cliff 

 when the subsidence took place, and afterwards under atmospheric de- 

 gradation and superincumbent pressure, the cliff being destroyed, its ma- 

 terial first formed a talus, and finally the heap now overlying the newer 

 beds. 



In the large exposure of the marl on the east slopes of these (western) 

 Chambal hills, mines are not now worked, and 

 but little is known about those which formerly 

 existedi Old mining works, however, occur in several places, and Dr„ 

 Jameson in his paper* states that, at about two miles distance from 

 Jutana, three mines were open in 1843. The inclined "shafts" which 

 varied in length from 140 to 180 yards, passed through several small salt 



Jutana beat inines.
