172 KING: KADAPAH AND KARNÜL FORMATIONS, [PART 1: 
marked. Where the outcrop strikes across the Chittravutty river reddish 
grey grits and sands in massive beds overlie the beds of conglomerate and 
pudding-stone which are full of fragments of carnelian and jasper. The 
rock is so crowded with these that it seems locally blotted over with blood- 
red spots; though it is generally full of grey, buff, brown, and blood-red 
bits of quartzite, carnelian, striped red and black jasper. The detached 
hills on this side of the river are capped with the remains of thick beds 
of an extremely coarse white and grey mottled reddish conglomerate. 
This is very much the usual constitution of the series all along this out- 
crop. The average thickness of this part of the series is about 500 feet. 
The unconformity of the quartzites on the series of limestones 
aconto eA beneath them is perhaps most clearly shown 1n the 
DEES sharp twist round from the long north-east scarp 
on the left bank of the Paupugnee, across the river southwards 
into the country on the right bank. The dip of both series of rocks, 
for instance in the low hills south of Boodyapully, is so low and varies 
so little that the unconformity is not seen except in long sections, as 
for instance along the southern face of the east and west spur of hills 
between Pugdallpully and Chinunulpenta. This low range of hills 
is capped by breccias and pebble beds of quartzites, which are on the 
north side overlying beds of the limestone series different from those which 
they overlie on the south side of the ridge. Here the bottom breccia 
beds are very ferruginous* and full of fragments of oolitoid chert. At 
the Paupugnee side of the hills the limestone outcrops are covered by 
grey brownish and reddish grits in thick beds, which strike into the river 
and appear on the other side as the beds which eventually turn round 
and form the scarped Annamalla ridge. 
* Mr. Charles Æ. Oldham notes this constitution as follows:—‘ South-east of 
Boodyapully the hill is of hard, grey quartzite, and in passing up the slope several bands 
of rich iron ore (hematite) are crossed; much of which is extremely rich, having quite a 
metallic lustre. It has been picked and worked, but fuel must be very scarce, the hills 
about being singularly devoid of jungle. The ore is very abundant, covering at least a 
square mile and coming well to the surface."
