HILLY RANGES AND THEIR NEIGHBOURHOOD FROM BAHADUR KHEL, &C. 1 L9 



In the nummulitic limestone above are some layers largely formed 



of shell fragments, apparently the remains of oys- 

 Nummulitic limestone. _ . . , , „ , -, . 



ters,* and higher up numbers ol the ordinary 



nummulitic fossils, generally in an imperfect state of preservation. The 

 limestone has much the same thickness as at the Kurshru Algud j it 

 curves with an increasing dip to the northwards, and occupies most of 

 the tunnel, by which the road issues from the salt valley into that of 

 Bahadur Khel, near which excavation it becomes nearly vertical. 



The usual lower beds of the tertiary sandstone series succeed, dip- 

 ping off the hill, but becoming rapidly perpendi- 

 cular along the southern side of the Bahadur 

 Khel valley and in the large nullah running along the foot of the salt- 

 quarry hills westward. Very brightly colored red clay and gray sand- 

 stones alternate ; they are either vertical or dip to the southward as a 

 rule, but half-way between Rogha (Raghu) and Bahadur Khel are 

 closely contorted. 



Towards the middle of the Bahadur Khel valley are soft gray 

 sandstones and red clays, with pebbly bands and occasional greenish-gray 

 shaly clays more or less covered by detrital accumulations. The dips 

 are generally high, and also to the south more frequently than in other 

 directions, the beds being probably a good deal folded here and there. 

 The character of the rock indicates a middle or even somewhat higher 

 place in the series. 



In the eastern portion of the Bahadur Khel salt exposure, the salt 



East part of salt ex- * s seen ^° f° rm an anticlinal arch with a dip of 50°

Tapu or boorj. From this towards Ragho it is more concealed by gyp- 

 sum with black shaly layers and by debris. Its stratification seems to 

 undulate, one dip to the westward having been observed, but to the south 



* It was presumably some such beds as these which Dr. Verehere observed, draw- 

 ing the inference that they were Jurassic from their resemblance to other shelly limestones 

 near Kalabagh.
