The deposits of in the detrital-ore. The yellow-tinted area on the 
detrital or talus-ore. plan shows the distribution of the loose deposits of 
manganese- ore composed of fragments derived from the manganese-ore 
in situ. Such ore is usually known in the Nagpur district as ' drift ' ore or 
' boulder ' ore. The former term is inadmissible, as it implies that the 
ore fragments have been drifted along by water or ice, and the second 
implies that the fragments are all large enough to be called boulders, 
which is not the case. As these loose deposits almost always consist of a 
talus of loose fragments of ore that have tumbled down from the ore- 
body in situ, a good name for them would be talus-ore j but to allow for the 
cases in which they have been somewhat rolled and arranged by water 
they had best be known as detrital-ore deposits. Both these terms will 
be used in this Memoir. Loose fragments of manganese-ore are, of 
course, found also outside the limits shown on the plan. I have 
attempted to represent only the area over which the ' country ' is more 
or less completely obscured by the talus-ore. 
The distribution shown is exactly what would be expected after 
taking into consideration the form of the hills (see small map attached 
to plan) and the dip of the rocks. The steepest slope down is oc the 
south and south-west sides of South Hill,'and as this is also the scarp'Side 
of the ore-body we naturally have here the most extended and thickest 
deposits of talus-ore. A similar large accumulation of talus-ore might 
have been expected on the north side of North Hdl. There, however, 
the total descent is much less owing to the ridge of gneiss tors a little 
to the north. That there is no considerable accumulation of talus 
manganese-ore down the western slopes from the saddle is due t'^ this 
part of the deposit consisting largely of spessartite-bearing rock
