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



BOULDEB BEDS 



a crushed denuded anticlinal fold occurring here. The succession is as 

 follows : — 



f 9. White crinoidal limestone. 

 Cabboniferous . -n g. Calcareous sandstone and limestone of rusty colour, Spvrlfera, 



V. Streptorhynchus. 



f (Concealment for many yards.) 



7. Very thick dark liver-coloured coarse sandstone and houlder-heds. 

 The latter are dark clays full of metamorphic, granite, and other 

 pehbles. 



6. Gray clay. 



5. Mass of shivered gypsum, red and white : dip north-west, high. 

 Much distorted layers of thin-bedded white, red, and gray gyp- 

 sum, alternating with thin gray dolomitic limestone ; bipyramidal 

 and other quartz crystals in one gypsum layer : another showing 

 large ripple mark ; may be 50 feet. 



4. Blackish-purple clay. 



3. Crimson and white, mottled sandstones and red clays, the latter 

 containing boulders of quartzite, red granite, dun-coloured 

 lithographic -texture limestone, &c, dipping at 80° to north, 

 west. 



(Interval 200 yards?) 



2. Mottled white, greenish-gray, and purple clay with coarse sand- 

 stone and gravelly layers, dip at 30° to north-west. 



1. Bed sandy clay with enclosed blocks of white, lavender, and 

 speckled sandstone. 



This succession is so often interrupted that the thickness of the different 

 parts becomes uncertain. From Nos. 1 to 3 inclusive the beds may be at 

 least 500 feet, and the whole group, which occupies more than half 

 a mile horizontally, can scarcely be less than 1,000 or 1,500 feet, un- 

 less a repetition occurs from the presence of an anticlinal, which is 

 doubtful. 



Shinki. 



The boulder beds are occasionally seen in ravines on the road to 



Shfnki from Omar Khel, but the slopes above are 



overrun by hard shaly and sandy limestone 



debris concealing the brown basal part of the carboniferous group. Near 



Shinki in a small Jcas some dark splintery and some sandy limestones 



occur, the lower part being fossiliferous and containing Products,
