220 KING: KADAPAH AND KARNÜL FORMATIONS. [PART IH. 
“The anticlinal fold west of Shingasanpully is, on the contrary, beautifully distinct, . 
and can be followed without any trouble northward or southward. To the northward 
it sinks rapidly and disappears with a fine elliptical curve of rippled quartzite under 
the Cumbum slates close to the village of Barticoonta. Southward, the anticlinal 
extends beyond the Konapully pass far to the south, and becomes eventually the main 
ridge of the Yellacondas. 
“The second anticlinal also appears to slope down to the north and disappear 
under the Cumbum slates of the Yamal-air valley. 4 
* The great flat anticlinal of the Pogulla ravine extends northward for a great 
distance and forms a leading feature in the ridge northward of the Gauly Conda. 
“ Hardly anything but true quartzite of buff or drab colors is seen in this section ; 
‘inliers’ of slate are very rare and altogether unimportant. In the Unkalumma Conda 
some of the quartzites are grey in color, but there can be no doubt of their being 
a continuation of the beds in the Konapully ghat spur. 
“The section now described affords a key to explain the obscure relations of the 
several quartzite ridges and slate valleys forming the mass of the Yellacondas further 
south near to Tellanela-mulla.

“ The beds of quartzite ‘which to the north of the Konapully ghat form a rather 
flat anticlinal arch, are, as they are followed southward, found to assume a very much 
greater inclination, having been squeezed up much more violently and to a considerably 
greater height. As the eye can follow the outcrops of these beds for miles along the 
mountain-ridge, no doubt can exist of their identity. Following the line of section 
(Fig. 36) across the Yellacondas at Tellanela-mulla Trigonometrical Station (about 
one-half of a mile north-west of the village), from west to east, the southern extension 
of the Konapully ghat (quartzite) anticlinal is found to dip under slates on either 
sile west and east. Those on the west are unquestionable Cum bum slates; those 
on the east must be the same, in the absence of faults, no signs of which were seen. 
These slates occur in a deep narrow valley running north and south from Konapully 
to Mylecherla. They are, I believe, the representatives of the Cumbum slates lost 
(ee Oo).
