118 KING : KADAPAH AND KARNÜL FORMATIONS. [PART ۰ 
The outside boundary, between these KADAPAH and KARNUL rocks 
and the crystallines of the Bellamkonta country, 
Outer eastern boundary 
faulted. is nearly for its whole length a faulted one; the 
downthrow having been on the west side, but it is 
a matter of extreme doubt how the fault-plane haded. If, as I sup- 
pose, there had been folding and inversion of the strata consequent on 
a crushing up of the country from the east, then the dislocations 
must have taken place in the axial planes of the inverted curves, and 
thus there would be a general hade to the eastward, the newer beds being 
thus at many points slid down underneath the older ones. 
This form of fault would account for the lie of evident KADAPAH 
quartzites over as evidently KARNÚL limestones ; 
Downthrow of rocks ۲ 
on west side, with a hade and also for the apparently enormous thickness and 
to the eastward, 
regular succession of limestones in the middle 
of the Palnád, which is totally inconsistent with their real strike and an 
overlie of the quartzites. One point is certain,—if there be a real overlie 
of the quartzites of the eastern ridges, they are perfectly conformable in 
the separate sections, while at the same time, on the whole, they overlie 
different horizons of the limestone strata. 
The following solution of the obscure stratigraphy of the Palnád 
beds is advanced, though with extreme distrust as 
My idea of the re- E j : : 
lations of the Palnéd to its being a possible settlement of the relations 
c of these beds:—There was general inversion and 
faulting of both KADAPAH and KARNÚL rocks along the eastern edge of 
the Palnád. In the Waumyconda range up to Karampudi the KARNÜL 
strata are lying naturally on the highest group of the Kapapan,* 
which is here unconformable on the next lower groupt of slates in 
the southern slopes of the range. The slates and shales overlying
