22 BLANPORD : GEOLOGY OF NAGPtJR. 



faulted against the intertrappeans, but the junction is ill seen, and 

 throughout the surrounding ground the rocks are concealed by alluvium. 

 From this point to the immediate neighbourhood of Nagpur, the only- 

 spot where any sedimentary rock was found intervening between the 

 traps and the subjacent formation, was at the little trap hill close to 

 Bokhara. 



Infratrappeans are seen on the edge of an inUer near Kampura, 

 south-west of Kelod. Below the earthy trap at the base of the igneous 



rocks there is a foot of green marl and then 1| to 

 Eampura. . . 



2 feet of red marl, both eontainmg much nodular 



carbonate of lime ; beneath these again apparently ( the section is 



obscure ) there is calcareous grit. Kamthis probably occur here, but 



they are not seen at the surface. 



Along the edge of the Chorkheri inlier, as already mentioned, 

 in&atrappean calcareous grit is seen at one spot only on the north-west 

 corner. * In the large Bazargaon inlier, it occurs along the north-east 

 boundary near the village of Ashti, and thence for some distance towards 

 Lonhara. In both the above instances, the rock is the usual limestone 

 with irregular nodules of chert. 



There can be no doubt but that the sandstone seen below the trap 



at the eastern base of Sitabaldi hill also belongs to the infratrappean 



or Lameta group ; it is a gritty tufaceous sandstone 

 Sitabaldi infratrappean. 



of a white colour mottled with red, and somewhat 



decomposed ; the total thickness is not seen, but it is apparently less than 



* About four miles north of Chorkheri, on the road from Nagpiir to Betul, close to the 

 Tillage of ChichoK, there is a small inlier about a mile in diameter entirely composed 

 of limestone, resembling the infratrappean bed. The rock is scarcely exposed, except in the 

 small stream which runs west and north-west of the village. In places it is finer in 

 texture and purer than usual, being free from grit and chert nodules, but in general it 

 presents the usual character. The bed is mostly horizontal, but it must be much thicker 

 than at other places. It is possible that this inlier is an intertrappean bed, the base not 

 being seen, and the intertrappeans occasionally, though rarely, assuming the same mineral 

 character as the bed at the base of the trap. But probably it is infratrappean.
