MALLET, VINDHYAN SERIES. 63 



considerably contorted and rolling sharply, as if from lateral pressure. The 

 sandstone in contact with the shales occurs in beds 6 to 9 inches thick, 

 lower down in flags. At Byhera Dabha in the Adh valley, resting on the 

 usual uneven beds of the Kymore sandstone, are 20 feet of greenish grey 

 splintery shales. Above this the sequence of the beds is greatly obscured 

 by several small slips, and nowhere is a continuous section seen, but the 

 following would seem to be the order. Above the strata just mentioned 

 is about an equal thickness of thinly laminated red shale containing 

 bands of very calcareous shale or impure limestone and covered by 10 

 or 12 feet of an impure limestone in beds ^ to 1^ inches thick, but divi- 

 ded into thin laminse by miiiute layers of calcite. At Badanpur gh^t 

 the highest beds of the Kymore sandstone are hard and compact, grejdsh- 

 white and reddish, the top bed containing rolled quartz pebbles up 

 to 1| and 2 inches diameter. Resting on this are alternate layers of 

 arenaceous shale and impure earthy sandstone (2 to 9 inches thick) 

 slightly contorted ; in thickness

This limestone is absent in the western part of the Rewah scarp. 

 South-west of Rewah the lowest beds comprise nearly 100 feet of red 

 earthy shale without any limestone, although it is slightly calcareous 

 near the bottom. At Badanpui- there is none either.
