748 MANGANESE DEPOSITS OF INDIA : DESCBIPTIVE. [PaRT IV : 
ttds ridge and in one place a thickness of at least 8 feet of bedded ore 
was thus exposed, the ore layers being 1 to 3 inches thick. The ore along 
this outcrop consisted st several places of tlie good hard grey variety, 
but at others was of inferior quality and sometimes interbanded with 
quartzite. Exposure 4 shows a sharp curve in strike accompanied by 
a dip in one place at 45° to W. 35° N. and in another at 30° to 
S. 18° W. It consists of hard grey ore spoilt by various impuri- 
ties, with also some softer ore. Exposure 5 consists of very garneti- 
ferous rock, runs for 30 paces N. 20° E. and lies on low ground. 
Now that I have seen the deposit after extensive work has been 
done on it, it is evident that each of the separate exposures described 
above really corresponded to separate masses of ore — except possibly 
Nos. 3 and 6, which, being on the same line of strike, may be connected 
underneath the dry tank between them. It seems to me that the pro- 
bable explanation of the relations of these separate masses of ore is 
that they were originally all part of one horizontal layer of ore. As 
the results of violent earth movements the portions Nos. 3, 4, 5, and 6 
have been cut off from Nos. 1 and 2, leaving these two portions in a but 
slightly disturbed condition, their separation one from another being 
due, not to the earth movements, but to the effects of denudation. The 
portions cut off from Nos. 1 and 2 were treated variously. No. 3 has 
been crumpled and faitlted. No. 4 has been pinched into a faulted steep 
synclinal fold surrounded by mica-schists, and No. 6 been made to dip 
very steeply. In addition to the portions noticed above the work has 
revealed the presence of some further, not very much disturbed, portions 
of the ore-bed. These lie between Nos. 3, 4, and 5, and probably 
actually once connected them together, but have since broken up at 
the surface into loose fragments of talus-ore more or less in situ. Ore 
in situ also seems to run to the south -west of No. 4 on to the low 
ground, beyond even the limits of detritus shown in figure 45. This 
was, of course, covered up by detritus, and only became visible when 
the ground was opened up. 
The hard grey ore mentioned above consists of the usual fine-grained 
Nature and quality mixture of braunite and psilomelane. Some 70 
of the ores. tons of Ore had been quarried at the time of my 
first visit — mostly from outcrop No. 3, but also from other parts — 
and stacked on the low ground to the west of the ore hillocks. From 
this ore I took sample No. 54. These stacks consisted largely of the 
braunite-psUomelane mixture usually more or less cavernous ; but a
