176 KING: KADAPAH AND KARNÜL FORMATIONS. [PART II1. 
reached, and here are quartzite, grits and sands again in well-exposed 
beds, which further to the north are arranged in an anticlinal. Over 
these are more sandy shales and then a fair thickness of white quartz- 
ites in a synclinal fold on which the Pollconda Pagoda is built. Over 
these come more sandy shales and red slates, which a short distance 
south begin to show traces of limestone beds, and, finally, these are 
overlaid (?) unconformably by the quartzites of Pollconda. 
The question is, do these quartzites with intercalated slates or sandy 
shales of the valley and the Pagoda all answer to the 
Quartzites beneath 
Polleonda Pagoda ap-  Poolavaimdlas (Naggerys) ? if they do, they have 
parently Poolavaindlas. 
thickened out considerably from what the sub-group 
is in the Annamalla ridges on the west bank of the Paupugnee; and 
an intermediate band of sandy slates has come in which does not show 
in that ridge. "There are also no traces of traps which are so promi- 
nent a feature on the Paupugnee. This last feature is of course ac- 
countable for by the possibility of the voleanic action not having 
extended in this direction. 
The final settlement of this question must only be left for closer 
examination than we have been able to bestow on this part of the field. 
Certainly there 1s a series of rocks, of which the Chintakonadinna beds 
are the lowest, extending southwards into the Chey-air country, and 
they to all appearanee have overlapped the whole of the Paupwgnee 
beds. But as these are traced out, it is found that the quartzites of the 
Polleonda Pagoda are those which are mainly ex- 
Pollconda Pagoda À ; 
quartzites are Naggery posed; the shales beneath and the quartzites of 
۷ the Boogoo stream in the section appearing in 
the western scarps. The group thus found to form the western side of 
the southern part of the field has then become the bottom series in. this 
region, and constitutes what we have ealled the * Naggery Quartzite T: 
from the well known and conspieuous Naggery Nose hill west-north- 
west of Madras.
