168 WYNNE : GEOLOGY OF THE SALT RANGE IN THE PUNJAB. 



d[d not appear here that the junction of limestone and shales was 

 regular, these having- been crushed into irregularities of the under surface 

 of^the]^limestone by slipping of the whole mass. 



The red sandstone brought against the limestone here seems to 



succeed the grey sandstones below regularly ; but 

 The sandstone. 



as the latter are oi the character or those belong- 

 ing to^the magnesian sandstone group, and no such strong red sand- 

 stones are known in a similar position among the upper beds to the east, 

 it is most likely that they belong to the group No. 5, which comes into 

 the succession not far to the westward. 



There is yet another locality at which the coal-shales are visible in 

 this neighbourhood, rather more than a mile to the 

 westward, under the salt miners^ old hot- weather 

 village of Nila, on the northern scarp of the tongue of limestone which 

 caps this spur of the hills. The coal is rather more than a foot thick, 

 occurring in the upper part of six or eight feet of black shales, under- 

 neath which a yellowish calcareous rock reappears, similar to that noticed 

 at the northern Samundri locality ; grey and ferruginous shales overlie 



the coal, and above them, just beneath the lime- 

 Associated rocks. . p, 1 •, 1 , 



stone, IS some line powdery sort white sandstone 



with carbonaceous markings. The whole group of beds associated with 



the coal from the limestone downwards is twenty-eight or thirty 



feet in thickness. 



Beyond the small capping of limestone, the rest of the ground 

 forming this spur is very much broken. The 



Oi^ripr rocks 



salt-marl rises high on the southern flanks of the 

 hills, and is much exposed in the deeper glens : the purple sandstone 

 cliffs start immediately from it, but the most of the higher ground 

 is covered either with light-coloured rocks, very generally sandstone, 

 of the magnesian sandstone group, or with their debris and that of the 

 overlying rocks.
