SEC. 6.] PORTION OF THE CENTRAL PLAIN NEAR BHOOJ. 171 



To the westward of Bhooj the plain becomes narrower, the ground 



using gradually from the sandy tract at the base

of the Charwar hills northwards by scarped 

 slopes to the elevated. tract called the Kootabun and the flat-topped 

 plateau which lies between the Kara river and Wurrar hill. The rocks 

 are all of the coarse, white, red, and other varieties of the upper group. 



A small trap intrusion of the ordinary augitic character to the 

 south of Ruttria has included and apparently 

 altered a mass of white sandstone which forms 

 a projecting crag. As it were enveloping this crag is a quantity of unc- 

 tuous purple, greenish and white saline rock, resembling an earthy lava 

 with white irregular amygdaloid specks; it occurs again at the east 

 side of the intrusion where the junction with the Jurassic sandstones takes 

 place, and is almost, if not perfectly, identical with the volcanic portion 

 of the sub-nummulitie rocks of many places. At Kalianpoor near ano- 

 ther intrusion a loose rubbly lateritic looking

rock With obscure relations occurs. A larger 

 intrusion forms a conical hill to the southward, and at Gowmuck to the 

 west, the hill, overlooking a sacred spring, is capped by coarse sandstone, 

 in places columnar, and with veins and knots of the red sandy looking 

 lava trap. This place is crossed by 'ramps' or reefs of silicious rock 

 running north of west and east of north, and sand, apparently drifted, 

 is heaped on some sides of the hills to an unusual height. Similar 

 ' reefs' occur in the neighbourhood at Mankooa. 



A small hiU of intrusive trap occurs at Kooarkee to the north- 

 north-west, and another, the basaltic trap of which

 of Kundwinga, the summit of which is also formed of intrusive trap. 



In the valley between the last named intrusions, a thick band of 

 shales is seen below the rocks of the plain faulted along a north-east
