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



limestone, and the tertiary sandstones generally, have strongly the 

 Murree aspect, purple sandstones alternating with bands of red clay. 

 Over these the beds assume a greenish tinge, gray and greenish sand- 

 stones alternating with the usual reddish clays. One mass of these 



Tertiary sandstones beds on the northern side of the ridge from Siree- 

 forming serrated outlines. me yla eastwards, steeply sloping and with serrat- 

 ed outline, repeats in miniature much of the aspect of the beds facing 

 the high Sheenghur (Shinghur) mountains as seen from this district.

are also not more free from faults than elsewhere, 



the chief effect of which is to cause the total absence, sometimes for 

 long distances, of the nummulitic limestone on one side or the other 

 of the main ridges. 



The narrow isolated limestone ridge of Wirshund north of Mal- 

 gheen (Malgin) has suffered such disturbance that

the same limestone rocks which form a compressed 

 anticlinal to the east are perfectly vertical along its crest and continue 

 so to its western termination. 



The general arrangement of the rocks will be understood from the 

 section in Fig. 15, crossing the Sireemeyla (Sirimela) ridge, the Drub- 

 bokus valley, and the mountains to the south.

Within a mile to the south-eastward of Sireemeyla (Sirimela) 

 Sireemeyla rock-salt occurs the last known exposure of rock-salt in 

 locallty * this direction, (it will be found described in the 



appendix). The salt occurs as usual closely associated with gypsum, 

 a long and narrow stripe of which runs from beyond this place 

 towards Weejoosum (Wijusum), forming the core of the limestone hills,
