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



but Dr. Verchere mentions " beds of massive gypsum " which are " not 

 extensive " " on the southern side of the hill near its base." 1 



The curves of the two anticlirials flatten, where they coalesce on the 

 Formations of the anti- co1 ; or ' divide/ between the heads of the Ha'sham 

 clmals - tanga and Thoru-ba-tanga or Khavuri ravines; 



and the easterly convex declinations of both are well exposed by the 

 excavation of the last named valley and upon the spur nearest to Paniala- 

 In the opposite direction the termination of the northern anticlinal is 

 equally well displayed near the ascent of the main road to the hill station 

 from the Pezu post, but that to the south expands, and its definition in 

 the neighbourhood of Chunda has been interfered with by the extent of 

 the denudation. 



Everywhere about the hill the effect of intense local disturbance, com- 

 pression, and great denudation are prominently exhibited, the folding of 

 the rocks being accompanied by sharp fractures, placing portions of the 

 crushed groups in complex relations of contact with other members of 

 the series. 



The rock groups are everywhere conformably disposed, the disturbances 

 communicated to each group are partaken of by the 



General relations. . ... „ ., ,. . . 



rest, but there is evidence or a considerable break 

 in the series at the base of the tertiary beds. Between these and the 

 Jurassic rocks, the whole of the nummulitic limestones and their conform- 

 ably superimposed lower tertiary sandstones, &c, are absent, and in their 

 place there is only a fugitive representative, — perhaps of the supposed 

 cretaceous sandstones of the Shingarh and Maidan ranges, perhaps of the 

 transition layers between the nummulitic limestone and the lower tertiary 

 sandstones which rest upon it. This band, occurring at the top of the 

 Jurassic beds and at the local base of the tertiaries, is composed of coarse 

 soft whitish-yellow sandstone, lithologically similar to the supra- Jurassic 

 band in the Chichali pass, but sometimes containing pebbles of num- 

 mulitic limestone like the lowest tertiary sandstone or uppermost num- 

 mulitic layers of the Maidan range at Mitha and elsewhere.
