NERBUDDA DISTRICT. 237 



The Lower Damuda and Talcheer Boundary.— I? we now return once 

 more to the western portion of our map, and carefully examine the line 

 of country we have just described, it will be apparent that the north 

 boundary of the lower Damuda and Talcheer was over-lapped by the 



Mahadevas, some beds of which group were de- 

 Mahadevas over-lap 

 the lower Damuda and posited upon the crystalline rocks beyond the 

 Talcheer Rocks. 



limits of the lower Damuda group in this direc- 

 tion ; also that the present boundary of the Mahadevas (as determined 

 by the fault) passed to the north of the northern boundary of the 

 lower Damudas, for the most part at least ; the only observed excep- 

 tion being that found in the Sitariva section above described, (see 

 Fig. 8, p. 169,) where the lower rocks extend considerably beyond the 

 Mahadeva boundary line, and stretch well out into the Nerbudda valley. 

 In the next place we are led to conclude that the old lower Damuda 

 The S. Boundary of and Talcheer boundary is itself a faulted one, be- 

 these rocks is a fault. cause although little of it can be examined, yet 

 in every place where it is exposed, this is seen to be the case. South 

 of Lokurtullye in the Morun river, at Bagra, in the glen south of 

 Futtipur, and lastly at Mopani in the Sitariva, the lower Damuda 

 rocks are more or less clearly seen to be faulted against the older rocks. 

 Besides which it appears that the older (lower Damuda and Talcheer) 

 and the newer (MahadevaJ boundaries are ge-

nerally, though not exactly, parallel. This is 



proved by the constant appearance of the former rocks, close on the 



south of the Mahadeva boundary, in most of the glens which have been 



hollowed out of the beds of the latter series. At Lokurtullye this is the 



case, again at Bagra, and in the little range which separates the Deinwa 



valley from that of the Nerbudda, the green mud and boulder beds 



often are found in the glens, close to the outer, or northern edge. of the 



hills of this minor range. South of Futtipur, the same thing again 



occurs ; and it is evident that these conditions could not obtain unless, as
