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



1c. — Tertiary purple sandstones, gray sandstones and purple clays much contorted. 



,;". — Nummulitic limestone with hard, gray, and white marly lumpy layers; some slightly 

 granular layers contain echinoid fragments and spines, nummulites rare. 



i. — Bright red clay. 



h. — Pale purple or brownish sandstone and red clay. 



ff. — White, marly, thin lumpy, and thin alveolina beds, and strong limestone. (This 

 limestone band is apparently cut out by a fault to the east). 



/. — Alternations of sandstones and red clay. 



e. — Pale brown sandstone weathering dark brown and olive sometimes containing 

 pebbles. Towards the upper part of the hill beds of clay of a greenish olive or 

 gray colour predominate. Limestone pebbles occur in the sandstones, and there 

 are small nummulites both in these and in the matrix. 



c. — Red-clay zone. Fault or Faults here. 



tl. — White and gray gypsum dipping generally to the north. 

 \a, — Greenish clay band in the gypsum. 



The gypsum is overlaid by red clay (c) which possibly represents that at/ and i, 

 and this is succeeded by the strong nummulitic limestone (d) which forms the 

 summit and northern surface of the hill, passing downwards into the Leeloohan 

 (Lihihan) glen. 



On the western side of Shah mountain overlooking the eastern 



Shah-drung salt local- nead of tne T" sna P ed g len previously mentioned 

 1 y * is the site of the Shah-drung salt in connexion 



with the gypsum, and just beneath the continuation of the red clay band 

 (c) in the above section. 



The difficulty of understanding this section by reason of the 

 inversion of the beds is increased by the dislocation 



Dislocation as well as 

 inversion obscuring the of the rocks. Two zones of bright red clay not 



seen in the Murdan Khel section occur here at 

 (/) and (i); one of these may be the representative of the red band (<?) 

 below the nummulitic limestone, but it is difficult to say which. In this 

 section the reversal is even more pronounced, the nummulitic beds/ 

 absolutely resting with some horizontality for a short distance upon the 

 lower tertiary sandstones, &c, and purple sandstones resembling these 

 are found at (h) in the same place as the band (5) in the Murdan Khel 

 section, and with the same appearance of intercalation, but less like ordi- 

 nary tertiary sandstone. The positions of the rocks are so strange 

 and there is such evident dislocation, it can only be suggested that the
