1.06 WYNNE : TRANS-INDUS SALT REGION, KOHAT DISTRICT. 



Overlying* this gypsum in proper order, gray clays occur again, the 

 red zone usually occupying this position being: 



Brown sandstones and 



gray clays : lower num- apparently dispersed among the gray series, with 



inulitics. 



some representative bands above near the base of 

 the overlying limestone. Over the gray clays are several feet of light 

 brownish sandstones rarely conglomeratic, and quite similar to that of 

 Shah mountains (Swanai Sir). The immediately succeeding Alveolina 

 limestone does not always form the very crest of the ridge. It 

 projects at Rago-tungi peak, but close by to the east sinks into the 

 face of the northern cliff, leaving the succeeding sandstones (here 

 containing a few small pebbles) to form the ridge. 



From the crest southwards the ridge exhibits much folding and 

 contortion of the limestone and sandstone beds, 



Contortion. 



the red clay zone being seen in its proper place 

 apparently, just within a large anticlinal curve of the limestone. 



A mile or so to the eastward of this section where the path to the 

 Manzulli Chowki runs, the southern side of the 



Inversion. 



anticlinal is inverted, the nummulitic limestone 

 beino- ao-ain overlaid by the gray argillaceous beds, and purple sand- 

 stones and red clays intervening between these and the gypsum, 

 but at a short distance further east, at the Thordrung salt locality, the 

 series regains its natural order, bending from the south over the ridge 

 into a long central glen of the range. 



A little rock-salt is here seen under a cliff of gypsum much over 100 

 feet in height, above which comes debris of green- 

 ish clay for nearly 200 feet more, then red clays 



obscurely seen, and then the nummulitic limestone on the crest of the 



ridge covered by a thin cap of the tertiary sandstones. 



The next section to be noticed crosses the ellipsoid near the 

 Section sonth-west of meridian 71° east, the rocks being very much the 

 sh;ukr - same, but the contortion seems here even surpassed
