238 NERBUDDA DISTRICT. 



we have stated, the older and newer boundaries had been approximately- 

 parallel . That they are not absolutely so is proved by the Sitariva 

 section (above quoted) where, instead of keeping south of the Mahadeva 

 boundary line, the older sandstones &c. are found north of it. 



We thus haye, for this part of our area, two distinct fault boundaries, 



namely, that of the lower Damuda or Talcheer, and that of the Mahadeva, 



nearly coincident at many points, and approximately, though not quite, 



parallel. And there is abundant proof that the 



Mahadevas unconform- # 



able to the older bound- fault producing the older boundary existed; and that 



the rocks had been denuded before the deposition 

 of the newer rocks. As for instance, in Futtipur glen, where the Tal- 

 cheer conglomerate is faulted against the crystalline rocks, and their 

 faulted junction overlaid by the continuous and nearly horizontal Ma- 

 hadeva conglomerate beds. 



Passing now to the south side of the Gondwarra hills, (see map) we

 South boundary ot the •> '

and west, and maintaining the strongly rectilinear direction so cha- 

 racteristic of the boundaries already described. 



This boundary runs from a little west of the meridian of Betul, to 

 a little east of that of Chindwarra, and is in both directions hidden 

 by the overlying Trap. It may be traced along the base of a well 

 marked range of hills of the crystalline rocks, which run nearly east 

 and west, and some of whose peaks rise to a considerable height above 

 the valleys below. Two of the most remarkable of these are Persakote, 

 and Muttardeo, each of which is formed of, and its prominence due to, 

 a very hard bed of quartzite, part of the schist series here. This rock 

 is mostly gneissose, and in places hornblendic, and its intense hardness 

 has resisted the denuding forces which have removed from either side 

 of it the softer layers of micaceous and friable schists. The strike of 

 the rocks is, as nearly as can be estimated, east and west ; and to any one
