10 BLANFORD :' GEOLOGY OF NAGPtJR. 



sliale is met with in places^ dipping south-south-west. This is the spot 

 at which Mr. Hislop obtained worm tracks. 



In this stream the beds are somewhat decomposed, and have not 

 the typical character of Talchirs. But in a very small watercourse 

 which runs from the north into that already mentioned, and which 

 is just south of the little limestone hill immediately east of the 

 Chhindw^r^ road, the typical fine silty shales are met with, breaking 

 up into minute flakes, and only differing from the Talchirs 

 of Bengal and Orissa in their duU red colour. Calcareous bands, also of 

 a red tint, and sandy layers are intercalated, as is frequently the case 

 elsewhere. Pebbles and boulders abound, mostly surrounded by a calca- 

 reous crust : some are rolled, many angular :

and besides metamorphic fragments, rolled and un- 

 rolled blocks of quartzite-sandstone and limestone from the Vindhyans* 

 are abundant, and many of them are of large size. Pebbles of slate 

 of unknown origin are also found. 



Some huge blocks of granitoid gneiss, seen east of this, may be 

 from the same boulder bed ; but farther to the eastward no rocks are seen, 

 and the whole country is covered with alluvium ; so it is also possible 

 that they may be masses in situ. To the north near Korh^di the meta- 

 morphies with limestone, as already described, come in beneath the 

 Talchirs. 



The only other place near Nagpur where beds have been observed, 

 which appear to belong to the Talchirs, is north of 



Patau Saongi. 



Pdtan Saongi, 14 miles north of Nagpur. All 

 around the village is alluvial, but, about two miles north of it, a 



* No Vindhyans are tnown to occur in the neighbourhood of Nagpfir, The nearest 

 now existing are prohably some hills lying east of Umred (Oomrair). But there can be 

 little doubt of these Talchir boulders having been derived from a distance as is so frequently 

 the case amongst these rocks.
