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

wardj and bears the nearest analog"y to a step-fault 



on an enormous scale^ repeating the features found in the scarp from 



Jalalpur to Jutana. The escarpment is high and steep, rising over 



the village of Chanod (or Chanad as spelled upon the map) to 2,290 feet 



above sea level. The base of the cliff is covered with a deep talus of 



debris and travertine conglomerate, but the salt-marl and gypsum can 



be seen in many places along its lower part ; and at one place, not far 



from the village named, a subsided mass shows the whole of the purple 



sandstone group capped by the shaly silurian band. 



In the escarpment itself both the purple sandstone and the shaly 



band re-appear and are continuous along it, but the 



Chambal scarp con- 



tinued. magnesian sandstone is only slightly represented, 



its development increasing to the northward. The red zone with salt 

 pseudomorphs is absent, and the lower beds of the tertiary sandstone 

 and clay series rest directly (where the succession is complete) on the 

 representative of the magnesian limestone or on the underlying silurian 

 band, without the intervention of either the olive series or the nummuli- 

 tic limestone. Three characteristic groups of the eastern succession 

 are thus missing, and among those that are present any want of 

 development seems to have been the result of thinning out, and not of 

 pre-tertiary denudation having removed any portion of them; so that the 

 series, limited as it is, still appears to be quite conformable.
