DETAILED DESCRTPTIONS.

Near Burwai. 



Near Burwai in the valley of the Chorul, there are some very- 

 interesting exposures of different rocks. BijawurSj 

 Vindhyans, cretaceous beds, trap and intertrap- 

 peans all occur, and metamorphics are found in the Nerhudda about 

 three miles from the town. 



The metamorphics in the Nerbadda are faulted against the Bijawurs ; 

 hornblend schists belonging to the former, coming against breccia, dipping 

 at 50° to the south-west belonging to the latter. The hornblend schists 

 are striking east-10°-north vertical; these schists contain small veins of 

 quartz and dykes of a trappean rock. This is close to the western ter- 

 mination of the rocky channel, narrowing in places to a gorge, through 

 which the Nerbudda runs from near Hindia ; at Burwai the river once 

 more emerges into an open plain and the banks only expose sections 

 of alluvium. The accompanying woodcut, (Fig. 5) from one of 



Fig. 5. Gorge of the Nerbudda, near Burwai, from the west. 



Mr. Wynne^s sketches, gives a view of this termination of the gorge just- 

 above Burwai ; the prominent bluffs on each side of the river consisting 

 of Bijawm- breccia, which is faulted against] the metamorphics beyond. 

 Close to this spot it has been proposed to build a bridge across the river. 

 A little further north, on the road from Burwai to Oonkarjee, the 

 hornblendie rocks are succeeded by whitish, slatey schists, with a very 

 different strike, west-15°-north. In these, lamina and irregular layere 

 of quartz occur as in the Bijawurs.
