45. Telakala Gadda. 
This deposit is situated about J mile S. 20° W. of Kam^vtaru 
village. The manganese-ore exposure is small. But the interesting 
feature is the way in which the manganese-ore deposit is being conver- 
ted into laterite by the growth of limonitic patches and processes, which 
gradually take the place of the manganese-ore and break it up into 
isolated patches, leaving pieces of the ore in the laterite. The final 
stage of the process is the complete disappearance of the manganese-ore 
with the formation of typical laterite, with all the characteristic vesic- 
xilar and tubular structures. Nearly all the manganese-ore seems to 
disappear entirely ; but a certain proportion of it separates out in the 
laterite in pyrolusitic patches, and sometimes the limonite forming the 
edge of the tubes is replaced by psilomelane. Associated with the 
manganese-ore is hematite, which is suffering the same conversion into 
limonitic laterite. The laterite in both cases often contains abundance 
of yellow ochre. 
47. Badapattl Banda. 
This deposit can be taken as typical of those on top of the plateau. 
The outcrop is flat, not sticking up much above the surface of the 
ground. It is also much corroded, so as to look very much like laterite. 
Consequently the true strike is difficult to see, but it is probably about 
E. 35° S. The outcrop is 11 paces wide with hematite cropping 
out on either side. After going 40 paces N. E. over hematite and 
laterite there is another band of manganese-ore 7 paces wide, mixed 
with hematite and much obscured by laterite. About 100 yards 
further N. E. there is another low outcrop, but it is reckoned as 
another deposit under the name of Kare-marada Banda. The typical 
ore of the Badapatti Banda deposit is dark grey psilomelane with 
veinlets of a bright crystalline mineral. There are also wad, magnetite 
specks, and a hght grey radiate mineral, in the ores. 
52. Alada-marada Banda. 
This is the deposit situated at the head of the apex of the triangle 
at the point where the line of manganese-ore deposits branches into 
two. The outcrop is on top of the plateau, but also goes partly down 
the N. N. W. slope of the valley. It is 112 paces long, and 46 across. 
The strike is N. W. with a doubtful dip to the N. E. at The strike
