120 KING: KADAPAH AND KARNÜL FORMATIONS. [PART II. 
this folding and inversion. This slaty look gradually ceases to the 
westward; and the shales then become like those of the KARNULS in 
the typical field. 
The general, though slight, unconformity of the limestones of the 
Palnád is clear in this way; that they overlie 
Unconformity of lime- 
stone of Palnád on the portions of different beds of the Kanaran quartzites. 
Din ah On the north-west slopes of the Waumyconda 
range, and its westerly continuation in the hilly part of the north-south 
arm of the Kistnah, the Palnád limestones are lapping up over upper 
strata of the series of KADAPAH quartzites. Again, in the low range 
of quartzite hills north of the Oopullapad undulation, the northern 
slopes are scarped to a slight extent, showing intermediate bands of 
shales and flags, below which are lower beds of this KADAPAH series 
which fill up the valley between this range and the next rise before 
reaching the Kistnah river. In this hollow, the limestones are lying 
on the lowest beds of quartzites (here denuded in one or two spots 
down to the gneiss itself). 
Now, if the limestones originally lay all over these undulations, 
they rolled up over the low scarps of slates and flags above referred 
to, until they joined the beds in the next southerly hollow which 
rest on quartzites higher than the slates and flags. Indeed, it is 
plain all round the edges of the quartzite undulations in the south- 
west part of the Palnád that the limestones are unconformable, for 
they are tailing up nearly horizontally over curved beds of quartzites, 
thus :—
