160 KING: KADAPAH AND KARNÜL FORMATIONS. [PART 111. 
There are very good indications of a more or less northerly and 
southerly line of faulting in the hills on the east 
side of the inner valley east of Gooleheroo, but 
their absolute direction is not clear. For example, the east-west

fault at the eastern end of the long valley, north of Goolcheroo, 
is continued into the northern base of the hill, east of the Cuddapah 
road, among quartzites: and, if one keep along in this direction, 
nothing else but quartzites and intercalated flags and shales are 
met with; yet in the little valley beyond this hill limestones and slaty 
shales are abruptly brought 1n on the western slope of the next 
hill, and show up that side of the turning up of the main valley. There 
is no trace of limestones between the east-west fault and Bankrapett ; 
nothing but quartzites which seem to be as much a continuation of the 
beds south-south-west of that village, as of those which are different 
and higher in the succession of strata to the north-north-west of the 
same village. These clearly north and south faults, however they run, 
seem to have died away to the south, for Mr. Charles Oldham saw no 
traces of dislocation in the hills east and south-east of Goolcheroo. 
In this way faulting, as well as covering up by the overlying unconform- 
able quartzites, may have had to do with the sudden disappearance of the 
Vaimpullys in this direction; though probably the last cause and 
thinning out have had the greatest influence.
