MANGANESE DEPOSITS OF INDIA : DKSCRIPTIVK. [PaUT IV : 
(and possibly more, but I did not follow it up) to the south-west side 
and 30 to the north-east side of the road. The rock is mostly fine- 
to medium-grained purplish spessartite-quartz-rock (gondite) partly 
altered to manganese- ore. Associated with the rock are muscovite- 
schists and some pegm.atite, while both in the 'Annapangree Nullah' 
and a little tributary joining it at this point the rocks seen are banded 
biotite-gneisses often penetrated by veins of muscovite-pegmatite. 
These rocks seem to dip to the south-east. The strike of this band sug- 
gests that it may be a reappearance at the surface of the Kosumbah 
band situated some 4 miles to the S. 30° W. To judge from the out- 
crop thi= occurrence is of no economic value. 
3. Sukli. 
(Central India Mining Company.) 
The deposit of this name is held by the Central India Mining Company 
and is probably the reappearance at the surface of the Sitapathur band.i 
The deposit forms a low hillock about 200 yards long ; the band contin- 
ues to crop out on the low ground to the south for another 250 yards, 
the strike being N. 10° W. with a shallow dip (up to 25°) to the west side. 
The only place where the ' country ' was seen was in a stream-bed at the 
south end of the deposit, where a granular quartz-pyroxene -gneiss with 
hornblendic bands was probably resting on spessartite-quartz-rock (gon- 
dite). Biotite-gneisses, biotite-schists, and pegmatite, crop out on the 
low ground separating the Sukli hillock from Sitapathur Hill. 
The ore-band is very variable in character. At the very south end

in places, except at the south side of the ore-hillock, where there is an 
interesting somewhat granular rock composed of spessartite, quartz, 
microcUne, and (_'rthoclase (?), the spessartite, which constitutes i to ^ the 
rock, being often enclosed in plates of felspar.

which is in Sukli limits.
