SJ5C. 6.] PORTION OF THE CENTRAL PLAIN NEAR BHOOJ. 161 



The hills near Kokma are formed of the usual upper Jurassic 

 rocks, showing an obscure [dip to" the eastward. The trappean grits 

 harder than usual, and accompanying] altered silicious sandstone, overlie 

 those to the west; while two small outliers of the stratified traps 

 occur to the north, apparently underlying some red and dark purple 

 volcanic-looking tufa and lateritic beds. 



Northwards from Pudder a low range of rugged sandstone hills 



rise from the plain at Chuprole, extending in a 

 North from Pudder. 



south-westerly direction by Kaleat-bowrie (ab- 

 breviated to Karetry) . Beyond this it is broken and crossed by the 

 valley of a tributary to the meeta (sweet) nuddi, but continues for 

 some distance, forming the ridge called Vatone Hill near Lakhan, which 

 terminates to the west in an intrusion of grey trap. 



Just near the village of Lakhan, some of the sub-trappean grits 



■re-appear, the river there crossing a pocket in the coarse upper Jurassic 



beds, occupied by these curious semi-trappean rocks, their bedding, where 



visible, being quite discordant from that of the underlying sandstones. 



North of this, the bold sub-eonical hill of Chan- 



Chandrua hill. 



drua rises to a height of 270 feet above the 

 plain (and probably 700 above the Runn, aneroid measurement). The 

 sides of this hill are very steep to the north and west, and expose coarse, 

 soft, white, red and pink sandstone varying to what might, for want of 

 a better distinguishing name, be called quartz gravel stone, with hard 

 ferruginous sub-granular bands so silicious as to resemble a brown 

 quartzite. The sandstones have indefinite white tubular casts like 

 annelid burrows or fucoids, and are so obliquely laminated, and so 

 amorphously weathered, that their true stratification is all but oblitera- 

 ted, in some places, however, appearing to dip to the east by north at 

 30°, 45°, and 50°. The white rocks are most prominent below ; brown 

 and ferruginous beds forming the uppermost part of the hill.
