A little to the south of Burar Hill is a ridge of crystalline limestones 
containing many accessory minerals, such as essonite. epidote, and pale 
green pyroxene ^ ; just to the south of this is a series of five small hillocks, 
the most eastern of which is about 100 feet high. They have a practically 
east to west strike and are composed mainly of spessartite-quartz-rock 
(gondite). The Ramakona-Devi road crosses the outcrop so that the 
most western part is just to the south and the remainder to the north of 
the road. The total length of the manganiferous band is a little over half 
a mile ; but it is not continuous over this length, the two eastern hillocks 
being separated from the three western ones by nearly a quarter mile. At 
the west end the band is cut off by a pink tourmaline-granite tending 
towards a granulite ^, whilst in the second hillock from the west end the 
manganese-band is interrupted by a coarse pegmatite of quartz and felspar 
containing large spessartite crystals up to an inch in diameter * ; this 
pegmatite may possibly be an intrusive cutting across the strike of the 
manganiferous band at right angles. 
The main mass of the spessartite-quartz-rock is fine-grained and 
partially altered to ore, but nowhere sufficiently so to be of any commer- 
cial value. At the western end the gondite commonly takes the form of a 
coarse rock of vein-like quartz and trapezohedral spessartite crystals up 
to an inch in diameter. On the two eastern hillocks some rhodonite was 
also .seen. The manganiferous band shows in two places, where it crosses 
nalas, widths of about 20 and 40 yards respectively. The dip is nearly 
vertical, being to the south on the most western hillock and to the north 
on the next hillock to the east. 
As will be judged from the foregoing remarks this band of manganifer- 
ous rock is much too fresh and unaltered to be of any commercial value, 
at least as far as one can judge from the outcrops.
