MANGANESE DEPOSITS OF INDIA : DESCRIPTIVE. [PaRT IV ; 
east of the, Kastur Nala.l Traced towards the nortli-east the outcrop 
is seen projecting from the alluvium, and on approaching Ukua village 
it begins to climb the slope of the mica-schist hills, reaching the summit 
(A 2,213 feet) atapomtabout J mile due north of this village. It next 
descends to low ground and then gradually climbs up the south-east 
slopes of a ridge of mica-schists, reaching the top at the north-east 
end, where the band apparently dies out ; the junction here between 
the overlying mica-schists and underlying gneisses is covered by the 
huge mass of laterite (both aluminous and ferruginous) resting on 
Deccan Trap basalt that forms the high hill north-east of Samnapur 
village and rises fui'ther to the north to form Tipagarh Hill, 2,76] feet 
above sea level, and one of the highest peaks in the Balaghat district. 
The dip of the rocks is always towards the north-west side 
of the strike at angles varying from 20'^ to 00° 
but usuallv about 30° to 40°. 
The greatest thickness of ore-band seen was at a point west- 
Thickness of ore- south-west of A 2,213, where the outcrop was 
h:it\d. 10 paces wide with a dip of 40°, corresponding 
to an actual thickness of 19 feet, which is not necessarily the full thick- 
ness. On the hill A 2,213 an actual thickness of 12 feet can be measured 
from the junction with the overlying mica-schists, but the base of the ore- 
band is not here exposed. 
The overlying rock is mica-schist (composed of sericite and quartz, 
often with ottrelite, tourmaline, rutile, and 
• Country.' . .... 
magnetite, or some other non-ore) varymg m 
places to mica-phyllite ; while the underlying rock is usually a schis- 
tose gneiss (which is evidently only a more metamorphosed form of the 
schistose grit underlying the IBalaghat deposit), this in turn resting on 
much less schistose gneisses. (See pages 311— 314). Between the ore- 
band and the gneiss there seems to intervene in places a little quartzite, 
but this is probably to be regarded as part of the deposit, as at Bala- 
ghat ; moreover, a little pit towards the western end of the deposit, just 
to the south-wcct of where the Gudma-Ukua road crosses the ore-band, 
showed that phyllites at this point also underlie the ore-band. At this 
pomt also there is seen a little manganese-laterite resting on the ore- 
body. 
1 On the south-west side of this stream (according to Kishen Singh's map) 
the band reappears and continues to Ghondi, under which heading this part of 
the band is mentioned (page 727).
