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



cally formed rocks were prolonged in these westerly regions to a later 

 horizon than in the Salt Range itself. 



From the escarpment the section continues upwards through the trias, 

 Escarpment section and either at the top of this or in the base of the 

 upwards. Jurassic formation, which now appears, there is, 



resting upon the uppermost triassic sandstones— here strongly developed — 

 a thick zone of light-coloured unf ossilif erous dolomite, very like the rock 

 upon which the unconformable Siwalik conglomerate rests at the extreme 

 northern termination of this range near Basti or Kundal. 



The series in the Kingriali cliffs and this part of the mountains is 

 as follows (see fig. 9 at page 78) : —
