 Along the scarp to the north, the most conspicuous beds, as usual, are 

 the massive purplish quartzite -sandstones.

large block of Bijawur limestone stands up in the 



bed of the river. Thence to the west trap, capped by the massive subrecent 



conglomerate already mentioned, covers the section for some little distance. 



Passing down the river, the traps are seen to abut against a mass of 



bedded brecciated and conglomeritic quartzite, striking east-10°-north, 



vertical. Along its southern side are a foot or two of softish sandy 



beds. It is succeeded on its northern side by peculiar red nodular 



rippled quartzose shales with interstratiHed flaggy sandstone-quartzite. 



A little farther west, down the river, the same beds are much crushed,
