294 Notes on the South Mahratta Country, fyc. [No. 160. 



Granite is seen in bosses and rocks near Lackmaisir, at Gujunder 

 Ghur and Noulgoond, underlying the sandstone at Mulgoond, in the 

 gneiss of the Kupputgode hills, at Gudduk and Dummul, and in the 

 districts bordering on the Tumbuddra and East of Gujunder Ghur. 



The largest dykes of basaltic greenstone, which I observed, were at 

 the West base of the Sitadonga hills, and in the Kupputgode range. 



Extent, fyc. of Overlying Trap. The southern margin of the great 

 sheet of overlying trap, which overspreads almost the whole of Central 

 and Western India and the Concan, runs across the northern part of 

 the South Mahratta country, covering all rocks except the laterite, 

 kunker, and regur, all which overlie it : entering from the Nizam's 

 territories by Firozabad on the Bhima, it descends to the Kistnah near 

 Churilaghi, near its confluence with the Gutpurba and follows with 

 some irregularities the northern bank of the latter river by Kotabangy, 

 a little to the N. of the falls of Gokauk to the W. Ghauts and the sea, 

 which it reaches a little N. of Malwan. 



The narrow zone of oliviniferous trap, crossed between the falls and 

 Koonoor, possibly connects the outlier of this rock on which Belgaum 

 stands with the main Coulee. 



North of the Kistnah the trap spreads over the Kolapoor, Sattarah, 

 and Poonah countries ; to the N. E. it covers the plains of Bijapore and 

 the Nizam's territories, stretching towards Gwalior. Where the trap 

 terminates to the W. of Belgaum is not exactly ascertained, as the 

 summits of the Ghauts near the Pass down to Vingorla are composed 

 of granite and the hypogene schists ; but the river Gutpurba, as has 

 been observed already, brings down a few calcedonies to the falls of 

 Gokauk. The amygdaloid noticed at Bangwari, and in the vicinity of 

 Belgaum, appears to have escaped the observation of Christie, who 

 states he has not seen this rock in situ. 



Classification of the Bocks of the South Mahratta Country. 



Christie, partly adopting the Wernerian system, has classed the rocks 

 of the South Mahratta Country under five heads, viz.: 

 1st. Granite. 

 2nd. Transition Rocks. 

 3rd. Old Red Sandstone. 

 4th. Secondary Trap. 

 5th. Alluvial.
