SHEKH BUDfN HILLS. 78 



From the top of the grind an extensive prospect is obtained. The soft 



greenish sandstone rocks of the Nfla Roh. with-

out a visible trace of vegetation, stretching from 



beneath one to the east-north-east, are seen to form a bold anticlinal 



curve, folding over the same axis as that of the northern lobe of the 



Shekh Budin mountain. To the northwards the same sandstones, with 



.gently dipping inclinations towards Agzar Khel, rise rapidly nearly 



to the vertical, as they border the gund, forming most precipitous 



and inaccessible ground intersected by steep valleys. Looking along 



the axis of the Bhatani range, which abuts against that of Shekh 



Budin gund, the convex curvatures of the bedding lines, in plan, as 



shown in Dr. Verehere's sketch, 1 are plainly seen, and the view is closed 



to the west by the massive forms and rugged outlines of the Suleman 



trans-frontier ranges. 



Where the main axis of the Nila Roh traverses the northern lobe 



of the mountain beneath the gund, it has, from

terminal pressure, assumed an upward curvature, 2 



and thus given to the Jurassic beds of this portion of the mountain a 



quaquaversal, ellipsoidal arrangement, enfolded at both ends by the 



tertiary sandstones, which enter deeply the synclinal trough perfectly 



coincident with the course of the Hasham tanga. 



Beyond this valley at its southern side, the same Jurassic beds rise 

 PanMla bluffs. Anti- steeply on to the Jangla ridge, forming part of a 

 clinal. similar, nearly parallel, anticlinal ellipsoid, which 



has been deeply eaten into and cut back from the plains to the line of the 

 Paniala bluffs. These grand precipices expose a fine but nearly inacces- 

 sible section down through the calcareous portion of the Jurassic rocks, 

 the variegated group beneath, the underlying triassic beds, and lower still 

 a portion of the carboniferous formation. 



I have not observed any of the infra-carboniferous beds in the section,
