116 KING: KADAPAH AND KARNÜL FORMATIONS. [PART II. 
After this statement of the anomalous stratigraphical features which 
beset the investigator in the examination of the 
Attempt at solution. 
Palnád rocks, it becomes necessary to offer some 
solution of the vezue But, so far, we confess to being unable to do 
this except by what is little better than a number of speculations found- 
ed on the sections and other features displayed by the rocks. 
The most reasonable way is of course to seize on the simplest form 
of explanation, viz., that the great spread of limestones is really a 
regular succession of strata one over the other in proper order going 
from north-west to south-east, and that the quartzites of the Bellamkonta 
ridges are not locally inverted, but really overlie the limestones. Could 
this be shown to be the case, there would then arise two conclu- 
sions, either that the Palnad rocks are all of the older or KADAPAH 
series; or, that the KaRNULS assumed in this region, not only great 
variations in the characters of their four groups, but altogether a greater 
number of these, and likewise that they here are largely intercalated 
with slates, as, for instance, in the section across the lofty Pulichinta 
ridge of hills (see Mr. Foote’s sections in notes on the Juggiapett 
field, in the Appendix). 
Considering, however, the constant character of the kamNÜrs over 
such a great area in the Cuddapah and Kurnool districts, it would 
seem safer to decide that all are KaADAPAHS rather than that such very 
differently associated kinds of rocks as those in the eastern part of the 
Palnád are KARNÜLS. 
Then, again, it is as difficult on either view to account for the 
presence of quartzite of the same series being at once above and below 
the limestones. 
It seems to me that the balance of argument is in favor of the 
limestones not being all of one series; and that 
Palnad limestone may 
be partly of xarnúrs where undoubted cases occur of the same lime- 
and partly of KADAPAHS.
