BHIMA smiES. 14S 



typical quartzites^ whilst a few yards off it can only be considered as a 

 fine close -grained sandstone. This bed is only 4 or 5 feet above the 

 o-neiss. The actual basement bed at this place is a brovvn pebbly conglo- 

 merate with rolled pebbles of quartz and gneiss. Amongst these, I 

 discovered what appeared to be a rolled fragment of silicified wood (or 

 bone ?) which was the only indication of anything' organic obtained 

 from any member of the Bhima series. 



An unusual form of sandstone resting on the thin basement pebble 



bed occurs between Tirth and Bazuna Kolur along 

 Schistose flagstone. 



the southern edge of the Tirth plateau. This 



sandstone has a quasi-schistose lamination, and separates into very rude- 

 looking flags. Much of this is due to the diagonal bedding on a 

 small scale, which is very frequent among the composing laminse of the 



rock. This sandstone has been used in the con- 

 Dolmens. • p 



struetion of a remarkably fine group of dolmens 



standing about half a mile west of Bazuna Kolur. The top slab of one 



of these was measured roughly; its dimensions were rather more 



than 11 feet by 8, with a thickness of from 10* — 1^" or thereabout. 



Owing to the great amount of talus accumulated along the foot of 

 the scarp forming the west side of the great Uguni valley, the lower part 

 of the Bhima series is hardly anywhere to be seen between Yeddihalli 

 and Fathipur (?) (Futtipoor) . 



At Kembhawi the basement bed is a brown pebbly conglomerate 

 filling a shallow bay in the gneiss rocks, but northward and eastward 

 of that place the basement sandstones and shales die out completely, 

 and do not reappear along the southern boundary of the Bhima basin 

 Basement bed at Ba- ^'^^ eastward of the Bhima river. At Bachimalli, 

 chimalii. ^]jg extreme easterly extension of the Bhima 



rocks in this region, the basement is a pebble bed, drab and pinkish- 

 white in color. The surface of this bed, which strongly resembles some 

 of the diamond beds of the Lower Krishna valley, is much broken up by
