CHAP. 5.] KARNÜL FORMATION.—THE PALNÁD. 109 
cannot be distinguished from the * Owk" shales and * N erjee’ limestone 
of the Jummulmutigoos. Beneath these again, come traces of quartzite 
sandstones and conglomerates, answering to the Banaganpilly group, 
and which in places have been worked for diamonds. 
The descriptions of composition and structure of the two KARNUL 
limestone groups already given are perfectly applicable to these two 
limestone groups in the Palnád, so that it would be a waste of time 
to redeseribe such similar rocks. 
With regard, however, to the two quartzite groups, there is not 
such a close resemblance. In the strata answering to the Paneums 
there are no representatives of the Pinnacled beds, though there 
are exact equivalents of the Plateau beds. On the other hand, the 
lower quartzites are so generally undistinguishable from the quartzites 
(KADAPAHS) on which they are lying, that it is hard, without a long and 
very close examination, which we could not devote to them, to say 
whether they are really true KARNUL quartzites or not. 
There is yet another exceedingly small and detached area of lime- 
stones situated about 10 miles further -W 
mE E ther south-west 
tached area on Kistnah than the extreme south-west corner of the 
plateau. 
Palnád, just at the bend which the Kistnah 
makes before running due north for some miles of its course. These 
beds are undoubtedly the same as the lower limestone in the Palnád, 
and are lying apparently quite conformably on the nearly horizontal 
quartzites of the elevated plateau through which the river flows in 
that region. 
In the Palnád, the rocks under consideration are lying in a flat 
zo A basin with only a few easy undulations, from 
which all but apparent traces of the bottom 
quartzites are denuded; the low hills towards the south-west corner 
of the field being thus partly made up of what look like Banaganpitlys.
