figure (71). It lies mostly 
on the southern slopes 
of a wooded ridge of 
micaceous quartzites 
running approximately 
east and west. At the 
eastern end a ravine 
divides this ridge from 
its continuation to the 
east, which is an isolated 
hill rising to about 200 
Scale 1" = 2 miles. feet above the ravine 
,oJ% '^l;.,^)^" * ^ ,*^",o n' and composed of vitreous 
(22), Piinchala (22AJ, Manegaon (2.}), Guguldoho (24), . 
and Bhandarb ri (25), deposits. quartzites Sometimes 
containing mica-scales and tourmaline needles, with an intercalated thin 
band of muscovite-schist. Thi? isolated hill separates the Manegaon 
ore-band from what is probably its eastward continuation, the Guguldoho 
deposit. The ore-band apparently dies out between these two 
deposits or else dives below the above-mentioned isolated quartzite 
hill. In the ravine is seen purplish gondite with mica-schists imme- 
diately to the south and probably quartzites to the north. The 
ore-band then rises straight up the ridge to the top, reaching an elevation 
of about 180 feet above the outcrop in the ravine. Going westward, 
the ore-band is found to leave the crest of the ridge and gradually 
descend the southern slope of the quartzite ridge nearly to the 
base, after which the western part of the band gradually climbs again 
to about half-way up the slope, and then disappears. 
The dip of the main ore-band varies of coarse with the strike, being 
almost invariably to the south side at angles which 
are nearly always high — 50° to 75° — , but sometimes 
approaching the vertical. The strike itself, although conforming on the 
average to the direction shown on the 
^ map, is locally very variable. Figure 
72 shows a good example of local 
twisting of the strike seen towards the 
middle of the length of the ore-band, 
where it rises to form a small hillock 
on the flank of the quartzite ridge, the 
ordinary strike about here being E. 
15°N. The rocks of the ore-band, on 
the hill at the east end of the deposit, 
often show slickensides striations. 
The direction varies from E.15°S. to 
Fie. 72.— Plan showing local twisting „ orotp pnalpQ of 9"!° tn 30°
