MANGANESE DEPOSITS OF INDIA : DESCRIPTIVE. [PaRT IV : 
4. Hatora- 
(Central India Mining Company.) 
This deposit is held by the Central India Mining Company. It 
crops out as a band striking about W. 10° S. for over g mile, the east 
end of the band being situated about ^ mile north-west of Hatora 
village. The dip varies between 15° and 40° to the south side. The 
immediate ' country ' on the south side of the band is seen towards the 
west end only, where in one place it is a quartzite containing abundant 
grains of iron-ore up to J inch diameter. This iron-ore is rather magnetic, 
but gives a red streak and is hence probably to be regarded as martite. 
It is often iridescent in purple and green. Still further west the rock 
apparently gives place to quartzite free from magnetite and then to a 
mica -quartz-schist containing magnetite. The immediate ' country ' 
on the north side was nowhere seen, but towards the west end muscovite- 
gneisses and mica- quartz-schists crop out on both sides of the ore-band. 
In the nala cutting across the western end of the ore-band and forming 
also the boundary to the Hatora village area, the ore-band has disappeared 
and the rocks exposed are biotite-gneiss, felspar-gneiss, and gneissose 
mica-schist. 
The ore-band crops out on low ground giving rise to very low ridges 
Character of the hillocks. Its thickness was nowhere seen, but 
ore-band. was apparently not very great. The outcrop 
consisted mostly of various varieties of spessartite- and spessartite- 
quartz-rocks (gondite), good ore being apparently very scarce. The 
spessartite is often quite large, being then of orange colour. In one 
specimen it is associated with glassy quartz, a brownish fibrous mineral, 
and a little interstitial microcline. The spessartite is here transparent, 
of a rich orange colour, and almost always shows hexoctahedral faces 
modifying the deeply grooved trapezohedra. Another specimen shows 
rich orange-red spessartite, the colour of potassium bichromate, on 
hard grey manganese-ore. A third specimen is of a bright yellow rock, 
almost the colour of sulphur, composed of a very fine-grained aggregate 
of spessartite, with small prisms of a white asbestiform mineral on the 
divisional planes. An abundant variety of gondite shows under the 
microscope the typical arrangement of very abundant small idiomorphic 
spessartites in a subsidiary quartz mosaic. It is often dark purpHsh 
grey in hand-specimens and this is seen under the microscope to be due 
to led hematite dust clouding the spessartites. At one point near the 
middJe of the ore-band is some intrusive felspar-rock containing abun-
