156 KING: KADAPAH AND KARNÜL FORMATIONS. [PART rit. 
And so on at various points, with the general formation of sands, 
The very coarse con- grits, and gravels, there were at intervals most 
glomerates decrease with 1 : 
fhe widges of ‘fault: enormously coarse conglomerates and breccias of 
Bin this fault-rock, occurring locally in the neighbour- 
hood of the runs which are now existent in the granite country outside 
of the KApAPAHs. And with the decrease of these walls or dykes of 
quartz rock, so the coarse breccias become fewer and fewer as the 
country is examined northwards. There is a splendid display of these 
features around the village of Uppaycherla which is close to the 
Cuddapah and Gooty high road. 
Again, still further north, between Goodypagd and the point where the Paipully 
Further cases of altered and Banaganpilly road crosses these rocks, the bottom beds 
jason of quartzite conglomerates appear to be altered along with 
the jaspery quartzose gneiss underlying them. About here, the number of jaspers, 
&c., contained in the gravels and conglomerates decreases for a time. Opposite 
Paipully, or rather west of Chellumpully, the quartzites run up and nearly cap a high 
ridge, the crest of which is of fault-rock : and here there certainly seems to have been 
some alteration of the KADAPAHS and CRYSTALLINES. The quartzites have a very 
altered appearance, and they are stringed with white quartz in an east-west direction, 
in the same way as is the fault-rock on which they are lying. 
Not far south of this at the east-south-east end of the great Waunaconda ridge, 
there are what seem to be unmistakable evidences of a contemporaneous alteration of 
the older and newer rocks. Here, the conglomerates and breccias are overlying distinctly 
foliated jaspery gneiss, and the bottom bed of coarse breccia is cemented, or fused into 
one and the same mass with the underlying gneiss. In places they are both impregnated 
with a pale, green, serpentine-like mineral, not unlike epidote, only that it is very soft.
