228 NERBUDDA DISTRICT. 



CHAPTER III. — FAULTS AND DISTURBANCES. 



In the commencement of this report a sketch of the general aspect 



of the Nerbudda Valley was given, or rather of that portion of it, which 



is included in our map. The remarkable physical features now to be 



more fully described, characterize with more or less distinctness, the 



band of country stretching from the Gulf of Cambay on the west, to the 



Ganges valley on the east, and including the Sone as well as the 



Nerbudda River. Most maps of British India

show a marked range, called the Vindhyan 



Range, running along this line; Mandoo stands near the western ex- 

 tremity of it, as generally shewn on the published maps, and Rotasgur 

 at the eastern end. In reality, as before stated, no such range exists ; 

 there is a well defined escarpment facing the south, but instead of being 

 a true hill range the slope of the ground from the summit towards the 

 north is very gradual, and slight. This line of escarpment joins the 

 north side of the valleys of the Nerbudda and of the Sone ; it deviates 

 little from a straight line, when considered as a whole, and even within 

 shorter limits, its rectilinear direction is very remarkable. Running

 been stated, of other rocks, and lying on the south side of the 

 Nerbudda valley, within our area. Beyond the district surveyed, a 

 very similar arrangement is known to form a continuation of the 

 range along the banks of the Sone, the south side of whose valley 

 has been found, (in part of its course at least) to be formed, like 

 that of the Nerbudda, of rocks different from those of the Vin- 

 dhyan escarpment. 



Any geologist who examines the accompanying map, PI. I., will not 

 fail to be struck with the very marked manner in which the different 

 geological boundaries coincide with the physical features of the country. 

 It is indeed generally the case that the experienced observer will
