158 KING: KADAPAH AND KARNÜL FORMATIONS. [PART III. 
About six miles north of this the jasper pebbles of the conglomerates disappear almost 
entirely. 
Again, north of the Coladunnakota tank the bottom beds of grit and conglomerate 
show signs of alteration. Here, the lowest bed is a dark 
bluish-grey vitreous quartzite grit with layers of white

pebbles, and it is not separable from the grey granite beneath along the surface of 
deposition. Many of the great fragments of this bed are lying about with the 
granite still adhering, as though the blocks were made up of one uniform rock. 
The high hill to the north of Raiculcoontapilly is much traversed by granite 
Conglomerate of adjacent veins, many of which contain a good deal of epidote; and 
granite. 
the bottom beds of the quartzites contain pebbles and frag- 
ments of this epidotic granite. 
Such are the kinds and the principal features of the Goolcheroo beds

crop broken by Gunny- is broken by a nearly east and west system of 
an faults which has affected both these and the newer 
KARNULS: so that the strata of both formations have been dropped 
down to the north with a throw of between 3 and 400 feet, and thus 
it is that in great measure the Goolcheroo quartzites are still left much 
further to the west on the north side of the fault than they are on the 
south side. 
North of the faulted line the strata still present much the same 
features as are seen to occur southwards, though they are even coarser 
grits, and rather marked as a set of pebble beds. 
Strata north of fault. 
The pebbles are remarkable for their roundness ; 
and even an uneducated eye would all along this scarp, and parti- 
cularly near Kurnool, be struck with the evident aqueous formation of 
these beds. The slopes and ledges of the scarp are strewn with as 
recent-looking river gravel as possible, all derived from the weathering 
away of these bottom beds. 
Most interesting and instructive examples of these pebble beds 
are to be seen in Jagernat Conda, just south of Kurnool; and again 
further south on the first ravine, where some temples have been built 
on and under the ledges of grits and gravel beds.
