256 NERBUDDA DISTRICT. 



which the Talcheer and lower Damuda formations were being deposited. 

 If, however, the distinctness in age of the Vindhyan fault be con- 

 sidered as unproven, (although probable,) it may be assumed to be 

 synchronous with fault No. 2, in which case we shall have those sup- 

 posed synchronous faults, No. 3 and No. 2, parallel to the fault line 

 No. 1, proved to be of a different geological date. 



Or, the Vindhyan fault may be assumed to have been synchronous 

 with No. 1, in which case we still have the supposed synchronous faults 

 No. 1 and No. 3, parallel to the fault No. 2, proved to be of a different 

 geological date. We believe, however, that the evidence brought forward 

 is sufficient to establish the stronger case, namely the distinctness in 

 age of the three great fault lines described, and that we have in the 

 lines of breccia, and again in the constant direction of the valleys and es- 

 carpments of the interior of the Mahadeva range, evidence which proves 

 that a tendency to yield in general east and west or more nearly north- 

 east and south-west lines has existed in this great area from the remote 

 period of the Vindhyan fault, up to that of the most recent movements 

 which have left any traces in the rocks of the country. 



There is another point of view from which the subject of the faults 

 and disturbances of this district may be considered. It is evident that 

 the following conclusions may readily be deduced from the contents of 

 the preceding pages. 



1st. We have in this district a rectilinear range of hills of great length. 



2nd. A second range also exists, strikingly rectilinear, and parallel 

 to the former, although not quite so perfect, or continuous as a 

 range, nor so accurately rectilinear as the former. 



3rd. The line of each of these ranges is coincident with a geologi- 

 cal boundary. 



4th. Each of these geological boundaries is a fault. 



5th. The interval of a geological period elapsed between the produc- 

 tion of these faults.
