258 KING : KADAPAH AND KARNÜL FORMATIONS. [PART 14 
The eastern edge of the Palnád is formed of ridges of quartzites over- 
lying limestones and slates at certain points; while at other points they 
are in turn overlaid by these very limestones. These quartzites seem cer- 
tainly to be of the KApAPAH series; but it is difficult, if not impossible, 
Kistnah beds on the 0 Say whether they are all of one group, or of 
win eem several, as the ridges are much broken by east 
and west eross-faults, in addition to north and south ones. 
The lowest quartzites of the Kestnah beds can be traced very clearly 
along the north-western edge of the field up to, and round to the south 
of, Batavole or Juggiapett ; but the southerly run is broken at the crossing 
of the Kistnah. It is, however, very probable that some of the ridges 
further south down to Nakarikallu are of these lowest quartzites. A 
great overlying series of quartzites and slates shows in the Pulichinta 
mass of hill, in the promontory south of Batavole, a description of which 
will be found in Mr. Foote’s. notes. 
The most difficult question, however, in the Palnád is to group the 
1 rc AI E limestones. As already related, the limestones 
cg HCE ES Dues. of the western part of this field are to all ap- 
pearance KARNULS, but in the eastern part of the field identical lime- 
stones underlie what are clearly KADAPAH quartzites, and in parts of 
the field overlie these also. 
It is impossible to account for this anomalous position of the rocks 
except by inverted folds, which style of folding certainly exists in the 
great inversions in the Waumyconda range; and which may have been 
prolonged into the smaller Nakarikallu ridges. In this way, it is suppos- 
able that all the limestones up to the eastern ridges are KARNULS, and ` 
so I have considered them; bat under this view there must follow an 
enormous inversion of all the slates and quartzites in the promontory 
mass of hills. I must confess myself quite at a loss to explain away 
such untoward stratigraphy.* 
* Mr. Foote’s notes on this area are given in Appendix, and may prove a key to the 
satisfactory solution of this difficulty.
