rocks are lying and their relations to the overlying Vaimpully slates 
and limestones. 
Near Dorragull* the Goolcheroos consist of about 150 feet of coarse quartzite 
grits and conglomerates in thick and massive beds, some of

which are slightly ripple marked: all dipping at 10°-12 
east-north-east or north-east down under the limestones, &c. Opposite the village, the 
scarp of quartzite cliffs is occasionally 100-150 feet high; but there is no scarp . 
opposite Timmanainpolliam. 
Further north, from Comanootla (on Vaimpully beds) to Pollconda,} the surface 
of slope is nearly all one bed or set of beds of coarse obliquely-laminated and gritty 
‘quartzite, dip being 10° eastward. Near the crest of the hills there is a very 
Pebble beds of jasper com- Coarse conglomerate, and then beds with layers of large 
msn: fragments of dark-red, brown, purple, and grey jaspers and 
carnelians. At the crest the beds are very coarse and thick, 3 to 6 feet each. These 
are the bottom beds, resting on the older metamorvhics. In the face of the scarp there 
are 70 to 100 feet of these beds. 
Again, in the Chittravutty gorge, the bottom rocks are very coarse grey sand- 
stones and conglomerates, the latter being full of large and small pebbles and rounded 
ds f lumps of quartz, quartzite, and jasper. The jaspers are 
generally of deep red and black colors arranged in layers : 
the black bands being ferruginous and many of them highly metalliferous with specular 
iron ore. Some of the lumps of ribbon jasper are as large as a man’s fist; and there are 
much larger rounded pieces of quartzite and coarse banded chert in the conglomerate. 
These lowest beds are not of any great thickness at this point, about 70 to 100 feet; 
but they are thick and massive of themselves. 
Just south of this, opposite Boodanumpully, the lowest bed of the quartzites is 
about 2 feet thick, of reddish brown sandstone literally crowded with semi-rounded 
fragments (about the size of a walnut) of quartz, jasper, and quartzites of red, black, 
brown, and white colors. Then come about 10 or 12 feet of coarse grits obliquely 
laminated, in beds of 2 to 4 feet thick. These are of a dark, grey color. Above come 
very thick and massive strata of coarse grits, which are layered with large shingle and 
rubble, with intercalated thinner beds. 
North-east of Peddakotla hill there is a gorge cut through the bottom beds by a 
tributary of the Chittravutty. The lowest beds are resting on quartziferous porphyry, 
and are of coarse, dark, purplish-brown quartzite grits and sands, with thick layers of 
ribbon jasper conglomerate. These layers are very distinct and mottled all over with 
white, black, and red pebbles, among which are occasionally coarse carnelians and onyxes. 
* Eastern edge of Bellary district, three or four miles north-north-west of Timmanainpolliam (last 
locality referred to in preceding notes of Mr. Oldham), and south of the Chittravutty river.
