Chap. XXXVIII. ] sandur : kamataru. 1031 
manganese -ore outcrop there is a spring issuing from the rock. It is 
iron-charged and is depositing its iron in the form of a limonitic slinw; 
as a coating on the masses of manganese- and iron-ore lying in the nahi. 
Mr. Ghose tells me that lower down, at the foot of a hill called Kiilhatti- 
marada Tattu, the water of this spring has deposited soft black 
manganese oxide on the rocks exposed in the n-dld. It seems probable, 
as far as one can judge from an outcrop, that the Durgsimma Kolla 
bands contain a large quantity of good -quality ore. 
55. Pilal-marada Gundu. 
As already explained this is really the third and lowest band of 
Durgamma Kolla, but it lies outside the limits of Sandur, being in the 
Reserved Forest of Tonashagiri, in the Bellaiy district. It also forms 
a sort of cliff. The ores are similar to those in the Durgamma 
Kolla bands. 
56. Karada Badasala Kativi. 
This is really a S. E. continuation of one of the Durgamma Kolla 
bands. The ores are the same except for one variety. This is an 
oolitic ore composed of ooUtes of lead-like psilomelane to 7 inch in 
diameter, very thickly crowded in a soft matrix giving a deep brown 
streak. This is the only occurrence of oolitic ores I saw m Sandur ; 
but Mr. Ghose says similar ores occur at several other localities. The 
ore is exactly like some of the oolitic ores of Mysore. 
63. Hunase-marada Kativi. 
This is one of the most south-westerly of the deposits on the Une 
running S. W. from Alada-marada Banda, and is about 2 miles south 
of Kamataru village. The deposit crops out along the edge of the 
plateau and is mostly very flat. The strike seen was E. 5° S. with 
a moderate dip to the north side. The length of the outcrop seen 
by me was 357 feet and the width 84 feet. According to Mr. Ghose, 
however, there is another outcrop to the north of this, that is 500 feet 
long and up to 200 feet wide. In one place there is a band of laterite 
apparently interbedded with the manganese-ore ; in reality it probably 
fills a cleft in the manganese-ore. There are also smaller patches and 
veinlets of laterite in the manganese-ore ; and interbedded hematites. 
The ores are similar to those of the other Kamataru deposits.
