MANGANESE DEPOSITS OF INDIA : DESCRIPTIVE. [PaRT IV : 
descriptions are based. As tlie result of their prospecting operations 
the Bombay Company, Limited, came to the conclusion that manganese- 
ore does not exist at Chik-Vadvati in paying quantities. 
The manganese -ores of the Sangli State are found at many points 
on the outcrops of the banded hematitic or limonitic 
p quartzites that form one of the members of the band 
of Dharwar rocks running N.N.W. — S.S.E. 
through Sangli, Bellary, and Mysore. This band was originally desig- 
nated the Dambal-Chiknayankanhalli Band by Foote, but has been 
re-named the Gadag Band for reasons given in the above-mentioned 
paper, page 97. Accompanying this paper is a beautiful map, on the 
scale of 1 inch = l mile, of the portion of this band lying in Sangli State. 
On this map will be found the various localities for manganese men- 
tioned below. The nearest railway station to this area is Gadag on 
the Southern Mahratta Railway. The village of Chik-Vadvati is 9 miles 
in a straight line S.S.E. of Gadag. 
Chik-Vadvati and Kelup. 
The manganese-ores appear ' to be best developed along the ridge 
Iving immediately east of the Chik-Vadvati valley. The rocky outcrops 
of the ridge as far north as the fault line shewn on the map are stained 
plack with manganese oxides The chief locality lies in a 
small gorge in the hills two miles east of Chik-Vadvati'. The containing 
rock is a banded hmonitic jaspery quartzite, striking N.N.W. — S.S.E. 
and identical in every way with some of the rocks of the manganese 
area of the Jabalpur district. The dip of this quartzite band is not 
evident. But the country on either side of the ferruginous band, which is 
a soft fissile chloritic schist, is seen to dip at about 40° to the E.N.E. 
The Bombay Company, Limited, prospected this locality for a period 
of 2 years (1903 to 1905) and sank over 30 pits along the outcrop within 
a distance of 1 mile. The deepest, of 50 feet, was sunk in a old working 
of 10 feet in depth, in cleaning out which some pieces of broken pottery 
were discovered. The other main work was the driving of two levels 
— 70 to 80 feet long — through soft decomposed schist until the ferru- 
ginous quartiite was reached, at a depth of 15 to 20 feet below the surface. 
The Bombay Company, Limited, has kindly suppUed assays, carried out
