Blanford: Sandstones of tlt,e Godavari valley.

About three miles west-south-west of Churcliuree and one and a half south-west of 
Chiraikoonin Sirgoojah, near the south-westboundary 
of Mirzapur, there is an abandoned lead mine formerly worked 
by a Mr. Burke. The rock in which it is situated is a reef of light-grey, rather shattered 
horny quartzite, running west-15 D -north, which cuts, parallel to the strike, through "rotten- 
looking earthy micaceous gneiss. At the mine it is double, there being one band of quartzite 
perhaps 50 feet thick, separated from a smaller one by some yards of the gneiss, which latter 
is intersected by many shattered strings of quartz. The quartzite bands have a hade of 60° 
to south-15°-west, the thicker being uppermost, and from the spots which were pointed out 
to me as those from which the ore had been extracted, it would appear to have occurred in two 
pockets; one near the lower side of the upper quartzite band and the other near tho upper 
side of the lower, in both cases near the band of gneiss which separates the two branches 
of the reef. I observed nothing indicating the existence of a regular lode. In some 
specimens of the quartzite obtained from the above-mentioned spots, the ore (galena) was 
very sparsely disseminated. Cerusite also occurs in small crystals, and I was informed by 
the Collector of Mirzapur that he believed antimony had also been obtained here. Of the 
latter, however, I observed no appearance.

the Godavari, and in the country between the Godavari and Ellore, by

The rocks near Raiglidem differ in no way from those further to the cast, nor do they 
require any description. Coarse sandstones and grits with 
Rocks near Raigudem. , . 
conglomerates and lerruginous bands are alone exposed. 
Rocks are seen, for a short distance, in the Pamaleru stream, from its confluence with 
the Godavari to just abovo Genkatapur, rather more than a mile in a direct line, thence none 
occur all the way to Pagalapali. In the Rala Yagu which comes from Gundalpad and 
joins the Pamaleru near Burgawai, much felspathic sandstone and conglomerate is exposed, 
of the usual character with a gentle north-west dip. In one spot nearly a mile from the 
junction of the two streams some pink and white argillaceous stone is seen in the Rala. At 
the junction with the metamorphics to Gundalpad no Talclurs are found. The bottom bed of 
the sandstones seen in the stream is soft and felspathic, grey in colour and conglomeratic with 
the usual Barakar character, but in a hill immediately to the south coarse loose textured pink 
and white sandstones are seen which precisely resemble Kamthls. 
The valley which debouches from the mass of hills to the eastward at Gundalpad consists 
TT .„ , of metamorphic rocks, like all the more eastern hills, 
including the lofty mass of Rajgota. But the hills imme¬ 
diately north and south of the valley consist of gritty sandstones. Their eastern boundary passes 
nearly under Rajgota, and is continued in a south-south-east direction for some miles; then 
it turns more to the eastward. From the peak of Rajgota a fine view is obtained over the 
sandstone country; the jungle clad hills to the south-west are seen extending away for many 
jniles, and the rocks of which they are composed have a low tolerably uniform dip, usually 
from abont 2° to 5°, hut occasionally rather higher, to the wost and west by north. It is 
evident with this dip and the direction of the boundary that the beds near Ashraopetta 
ought to be rather lower in the series than those near Gundalptid; the former may represent
