sections are exposed, as near Putria village, near Kotri, north of Hirapur, 

 north of Kerapassi (see Section No. IV on map and which may serve 

 as an example typical of these cases). 



The general character is as follows : 



The nearly horizontal beds of the Vindhyan series are cut off in a 



vertical scarp, and at a short distance south of 

 Description. 



this, a mass of sandstone is found often rising in 



a conical hill, or a saddle-backed east and west ridge, to nearly the 

 height of the top of the escarpment, as represented in the diagram 

 referred to. This hill or ridge is formed of vertically, or nearly verti- 

 cally-bedded rock, often very similar to that of the neighbouring escarp- 

 ment, but more frequently showing traces of a lithological alteration. 

 It is, when this is the case, traversed by numerous quartz veins, and 

 looks as if the rock itself had been impregnated with infiltered silica. 

 Often this altered character is very greatly developed, and the rock then 

 becomes a breccia, formed apparently of fragments of shattered sand- 

 stones re-cemented by infiltered quartz. Immediately behind, (that is 

 south of) this breccia, we generally find the schists (see diagram 

 Section IV) of the Nerbudda valley. Here there is an evident case of a 

 fault with a down-throw towards the north, whose course is marked by 

 the upturned bed of sandstone, and by the breccia. 



In the localities above named these features can, as stated, be clearly 



seen ; elsewhere we only find traces of the breccia,

and not a prominent hill formed of it, to the south 



of which traces of the schists appear, indications which are, however, 



sufficiently explained by the better seen sections such as those above 



described. 



But the nature of this fault is perhaps still better seen near a little 



village called Pullassi, which is shewn at the west-
