MALLETj VINDHYAN SERIES, 79 



bedding generally is not so thick or massive as to the east. In places, as 

 between Dhari and Eampura (north-west of Punassa),, some portions 

 are conglomeritic, even passing into conglomerate. The pebbles are 

 mostly under an inch diameter, composed chiefly of variously colored 

 quartzite and red jasper. The matrix is often dark purple, and 

 the rock then bears a strong resemblance to some varieties of the 

 " hornstone breccias'^ of the Bijawur series. Indeed it is very doubtful 

 to which series certain rocks of this class should be referred. 

 Some beds of the Rewahs have evidently been made up almost wholly 

 of debris from the Bijawur hornstones, and as they (the Eewahs) have 

 been considerably indurated, they naturally bear a close lithological 

 resemblance to the older rocks. South of the Nerbudda, in the neigh- 

 bourhood of Chandgurh, such diflGlculties frequently occur. One case was 

 observed where a red breccia between the Bijawurs and Vindhyans 

 contained large pieces of a rock similar to itself. Here there could be 

 little doubt that the rock was Rewah and the fragments Bijawur, but 

 other cases are not so clear. 



Regarding the upper Rewahs in Bundelkund there is little calling 

 Bundelkund ^^^ remark. Their lithology is identical here and 



to the east where they have been already described 

 and their thickness seems very uniform. Like all the other members of 

 the series there, they dip gently towards the south, a result of original 

 deposition, not of subsequent elevation, and throughout, the inclination 

 of the strata seems to coincide exactly with that of the glacis which 

 stretches from the edge of the Rewah escarpment to the boundary with 

 the Gunoorgurh shales, a fact of very general application amongst the 

 Vindhyan sandstone slopes. East of Sagar the strike of all the 

 sub-divisions takes a sudden turn to the south, and the Rewahs contiaue 

 past Soorkhi. There can be little doubt that they underlie the trap 

 between that place and the Nerbudda valley — the whole Bundair group
