CHAP. 2.] KADAPAH FORMATION.—PAUPUGNEE BEDS. 159 
The beds north of the fault are also remarkably felspathic in their 
constitution, the felspar being often of a red color

and crystalline, giving the rock occasionally almost 
a granitic look. It is very possible that some of the felspathic grits 
oceurring on the right bank of the Toongabudra below Kurnool, and 
referred to by Mr. Foote as of the Banaganpilly group among the 
KARNUL ROCKS, may be really bottom beds of the KADAPAH SERIES. 
At Kurnool, there is a very clear section exposed in the long canal 
Bottom beds thinning Cutting near Jorampoor, in which the bottom 
gN aroo beds of the KaDAPAHS are seen overlying a 
very irregular set of hornblendie and silicio-felspathic crystallines which 
are much traversed by trap. The bottom bed is very irregular in its 
thickness, seeming to have been thinly spread over the gneiss and 
oceasionally thickening out slightly where it filled in the denuded 
hollows; and it is waving along gently, as a shore-bed might do on a 
roughish bottom. It is here a very coarse breccia and conglomerate 
of fragments of white and glassy quartz in a matrix of dark, brown, 
earthy silicious rock which was possibly derived from the wear of the 
silicio-felspathic bands occurring among the CRYSTALLINES to the south 
and south-east of Kurnool. This bottom bed is then covered by a 
thin set of quartzite grits and sands, which in their turn are overlaid by 
slaty shales. These make up a very thin set of beds: altogether hardly 
more than 40 feet thick at their greatest depth, east of Kurnool. 
Vaunpully Slates and Limestones. 
Throughout the length cf outcrop just described, the Goolcheroo 
quartzites are overlaid apparently conformably by a series of shales or 
slaty shales and limestones which at Goolcheroo thin out and 
Die out east of disappear, as already stated, between the bottom 
Gooleheroo. \ quartzites and others of the long eastern sloping 
hilly country between Goolcheroo and the higher ranges of the Pollconda 
hills south-south-east of Cuddapah.
