MANGANESE DEPOSITS OF INDIA : DESCRIPTIVE. [PaRT IV : 
This band has been traced below the surface by means of a series 
^ ^ of pits for about 400 yards in a westerly direction 
Length of ).nH beyond the western end of the outcrop included 
within the concession of the Central Provinces Prospecting Syndicate. 
This extension, which is being worked by the Central India Mining 
Company, will be described separately as the Mansar Extension ; taken 
together with the concession of the Central Provinces Prospecting 
Syndicate it gives a total length of H miles for this ore-band, or if the 
Parsoda deposit (of the Central India Mining Company, page 893) be 
regarded as a part of it, then the total length is over 2 miles. 
On both sides of the ore-band the immediate ' country ' is very similar 
. Q ^ , t^^^ of the Kandri deposit, and consists mainly of 
ountry. ^ fine-grained light- coloured gneiss, usually con- 
taining abundant scattered specks of a black slightly magnetic mineral 
(? mangan-magnetite). This gneiss is interbanded with layers of vitreous 
grey quartzite, of yellow spessartite-rock partly altered to ore, and of a 
very fine-grained, friable, white mica-quartz-schist. The best section on 
the south side was seen in December 1906 alongside the incline No. 1 
South, near the west end of the deposit. This section showed, measuring 
horizontally (the dips being steep) : — 
1. Ma,nganese-ore forming the southern wall of ore-body; 
2. 10 paces of ir.terbanded rocks, as above noticed, passing down into 
very quartzose mica-schists ; 
3. 10 paces of mica-schists with quartz lenticles. 
To south of this the fine-grained gneisses were again seen. 
On both the north and south sides of the ore-band the felspathic 
gneisses and interbanded rocks give place further from the deposit to 
mica-schists ; whilst quartzites form low hills both to the north and south 
of the ore-ridge. Hence the generalized section across the ore-ridge, from 
north to south is, as far as can be at present judged : — 
1. Quartzites, 
2. Mica-schists, 
3. Interbanded fine-grained gneis ;cs and mica-quaitz-schists, viterous 
quartzites, and spessartite-rock, 
4. Ore-body, ! 
5. Similar to 3, - 
6. Mica-schists, 
7. Quartzites. 
Figure 58 is a north to south section across the hill at its highest point 
and is based on surface evidence, both along the line of section and in 
openings to the west of it. It is intended to be diagrammatic only.
