XII. An Account of some Minerals collected at Nagpur and its Vicinity, with Re- 
marks on the Geology of that part of the Country. By Captain F. Jenkins,/;/). 195 
to 215. 
Nagpur, the capital of the Berar state, is in Lat. 21° 10', Long. 79° 14'. It is 
situated on the bank, and nearly at the source of the insignificant stream, the Ndg 
Nadi. The elevation is about one thousand feet above the sea. Its site is inter- 
esting in a geological point of view, being the pointof junction of the great western 
trap, with a great granitic formation, the extent of which is yet but partially deter- 
mined. Captain Jenkins considers it to be part of that found on the confines of 
the plains of Bengal, reaching from the Ganges below Patna to the sea at Ganjam, 
and a continuation of the great ranges of the coast traceable probably above ground 
through this vast extent. 
“ The hill of Sitabaldi, the extreme eastern point of the trap formation, would ap- 
pear to be insulated from the range of hills to the west of it ; or its connection is 
by a narrow neck ; for the sinking of wells round the base of the hill has shown it 
to be nearly, if not entirely surrounded by gneiss. This gneiss is at its base 
much decomposed, and of a greater elevation than the next adjonning uncovered 
gneiss in the city ; which is, however, extremely shattered, and the whole hears the 
appearance of having been up heaved and disturbed by the basalt.” Cancar is abun- 
dant in the neighbouring soil. 
“ To the west, north west, and south west, trap entirely prevails ; to the north 
east , east, and south east, black soil in the immediate neighbourhood prevents the 
observation of the underlying stratum ; but there is little doubt of its being gneiss, 
as this is the nearest rock displayed in those directions.” To the north decayed 
gneiss is met with, but only for a short distance ; after which the same deep soil 
covers all vestiges of rocks till we reach the granite of Waragaon and Suradd. 
“ This granite of Waragaon is remarkable for the great quantity of felspar in it, 
from its having no mica, or a very small quantity, and the quartz being chiefly 
disposed in masses, and exhibiting frequently large cavities lined with fine crystals.” 
Dolomite is found at Khorari, west of Waragaon, and about six miles north of 
Sitabaldi. To the west of this point is the trap range. 
“ Near the cantonments at Kamti is found sandstone with an argillaceous cement 
and disseminated spots of mica. The dip appeared to be south. The rock is 
much broken, and the fissures, horizontal and vertical, are filled with seams of lime 
(-stone) about half an inch to an inch in thickness. It is covered near the village 
by earthy red iron ore. Granite and gneiss have been found in digging several wells ; 
but under snch circumstances as to leave it doubtful whether they were huge boul- 
ders belonging to a bed of conglomerate known to exist, or real bedsor veins of those 
rocks. There is a ridge of gneiss at the extreme left of the cantonment, so that the 
latter supposition has this circumstance to favour it. 
At Sihvara, north of Korari about two miles, are extensive quarries of argillaceous 
sandstone ; the strata are very regular, though of unequal thickness, and dip to the 
south, at an inclination of about 30° to 35°. Between Silwara and Patan Sangi, the 
sandstone rises into a low hill, upon the surface of which lies conglomerate. It is 
also found near Sfinflr in the bed of the stream, and appears to cover an extensive 
tract beyond the pass of Kelode on the road to Sindwara. 
Nortli of Kamti on the high road to Ramtek no rock is found at. the surface, hut 
in a well about half way, and at the depth of 30 feet, a decomposed granite is seen, 
and boulders of quartz with schorl disseminated are found in a neighbouring nul- 
lah. The swell at Satak and Nagardan is also quartz. Close to Ramtek again gneiss 
begins to appear. North of Ramtek, the first range of hills is quartz rock : further 
on gneiss occurs, and at Dongertal, eleven miles from Ramtek, the hills are of gra- 
nite. On the south arid west are beds of marie affording tolerable lime. 
On entering the jungle towards Kunmri white disintegrated micaceous schist 
appears, and further on red limestone in considerable mass, having an east and 
west direction. Granite veins occur in it, which by the wear of the limestone are 
left standing up two or three inches high like protuberances. This rock passes 
into one, consisting almost entirely of manganese.
