64. KING: KADAPAH AND KARNÜL FORMATIONS. [PART 1I. 
While deseribing. this oceurrence of tumbled masses of white 
Mode of weathering quartzite strewing the slopes of the hills capped 
RE ما‎ by this rock, it is necessary to warn the observer 
against concluding that certain other tumbled fragments of quartzite 
which strew the slopes of a range of flat-topped hills in the Cuddapah 
district, between the Paupugnee and Chittravutty rivers west of the 
Gundycotta range of hills, are of this group. These last are of quite 
a different group of quartzites to be described hereafter, and it is not 
difficult to distinguish them. The fragments of the pinnacled beds are 
nearly always more orless white in color, and very nearly cubical in 
form, that is, they are of a good thickness as compared with their length 
and breadth. The fallen fragments* to be distinguished from these 
are of coarse grits and sandstones (quartzite) of dark colors, and more 
tabular in form than the Paneum fragments. 
We have not been able to recognize anything of organic structure 
in this group: the pinnacled beds occasionally show a rather curious 
concretionary structure of a globular shape, but these bodies are all made 
up of sand. The beds show frequent examples of ripplings, particularly 
the plateau quartzites. 
It has already been related how the quartzites of this group have 
thinned out at Kypaw; but there is clearer 
ca evidence than this of their having died out alto- 
eether along the eastern side of the Khoond-air valley, where there is not 
a single instance of outcrop from under the Khoond-air limestones in 
any of the sections exposed; the shales that are found lying under- 
neath the quartzites of Banaganpilly hills, &c., appearing directly 
under the Khoond-airs. The Kypaw section is a very interesting one; 
itis most difficult to find out where the rest of the quartzites, which

* In the locality where they occur the people of the Cuddapah district liken these 
tabular masses to troops of frogs ascending the hill sides, and have built up a legend on 
the resemblance.
