68 WYNNE : TRANS-INDUS EXTENSION OF THE PUNJAB SALT RANGE.

150 feet, is occasionally exposed close on the bank 



of the Indus, appearing from beneath shattered and disturbed carboni- 

 ferous limestone layers. Here the beds with boulders are somewhat below 

 the top of the group ; they contain blocks, up to one and a half feet across, 



of red granite, dark basalt, limestone, white meta-

morphic limestone, quartzose and other indurated 



rocks ; imbedded in a dark grey clay : the assemblage strongly recalling 



both the western Salt Range infra-carboniferous beds and also the 



much newer conglomeratic clays of Chel hill in the eastern part of that 



range, supposed to occujiy a cretaceous horizon. 



Many of the blocks are smooth, parts quite so, almost polished, and 

 on these surfaces some show slight striation in two directions ; these 

 were rendered more visible, while wet, by washing the boulders in the 

 adjacent river. 



The limestones of the range here and towards Kingriali summit are 

 much curved in different directions, and they form a short and rugged 

 ridge parallel to the main crest of the range, the undulation of the beds 

 producing at this locality the widest surface exposure of the carboni- 

 ferous group in the whole range. 



Accompanying this expansion the height of the range increases, but 

 is not given on the maps. By a rough angular observation, compared 

 with aneroid readings, it was conjectured to have an altitude of 3,150 feet 

 above the sea.

 characteristic appearance of the bolder Salt Range and trans-Indus
