MALLET, VINDHYAN SERIES. 



^3 



The thickness of limestone here is about 360 feet. The shales are 

 finely laminated, not differing much in composition from the sandstones. 

 They are slightly more earthy, which determines the difference in strilc- 

 tm'e. These alternations of hard* and soft "bands produce a deviation 

 from the ordinary outline of the escarpment. Instead of one cliff and 

 under-cliff, the escarpment is broken up into a series of terraces, of 

 which the upper are sometimes worn back a considerable distance from 

 the lower ; even as much as a mile and a half. The following examples 

 tbie selected in illustration : — 



At Sewar we have blue (Bundair) limestone at the bottom of the 



scarp and then

The lower Bund'airs where exposed in the valley north-east of 

 Kerowlee do not present any mai-ked lithological 

 differences from the same beds in the Dholpur scarp. 

 Their stratigraphy, which is rather complicated, will be best described in*
