244 WYNNE : GEOLOGY OF THE SALT RANGE IN THE PUNJAB. 



The nummulitic limestone of the summit of the mountain does not 

 form a horizontal cap^ hut is bent into anticlinal and synclinal curves^ 

 having an east-and-west direction or following the crescent-shaped form 

 of the hill; valleys having been excavated and minor ridges left between, 

 with only a very slight relationship to the contortions of the strata. On 

 the crest of the mountain the nummulitic limestone beds dip generally 

 southwards, but are so curved, at some distance down the hill-side in 

 that direction, as to crop outwards from the surface. On the northern 

 slopes the beds are inclined with the ground, but they have been cut 

 through by denudation, leaving some of the basal nummulitic hsematite 

 exposed, as well as one large and several smaller patches of the Jurassic 

 rocks. The latter are here chiefly white sandstones and rusty-yellow 

 earthy beds with calcareous layers containing TerebratnlcB, Belemnites, &c. ; 

 they are conformable to the nummulitic beds, and dip with the northern 

 slope of the ground. At the foot of the mountain in this direction and 

 for some distance up its flanks, the surface is covered with debris of 

 the nummulitic and tertiary sandstone groups, the latter rocks being 

 exposed in the deeper stream-courses at a considerable distance from the 

 limestone of the mountain side.* The structure of Sakesar and adjoin- 

 ing ground will be seen from the section, fig. 45, Plate XXVI. Near 

 the base of the red earthy zone overlying the lower tertiary sand- 

 stone beds and in a direction north-by-east from 

 Salt chowki. 



Sakesar summit, is a salt watch-house placed to 

 guard some saline streams and efflorescence similar in character to that 

 which frequently occurs in the lower portion of these tertiary sandstones 

 and clays, but in larger quantity than usual. 



* Some very good bungalows liave been built near the summit of Sakesar to supply 

 the want of a sanitarium for Shabpur and Miawali stations. A good road leads to these 

 from the Son plateau, and a very bad one down the northern slopes via Miawali Dok to 

 Namal. The situation is lofty but bleak, there being little vegetation, and supplies have to 

 be brought from Uchali, a distance of several miles.
