confluence, the Koilkoontla limestones east of the village are seen to 
graduate downwards by thin sub-earthy limestone flags into the shales 
at the top of the following section, given by Mr. Foote as measured 
below the north tower of the village fort :— 
* Greenish-grey, brown, drab, and bluish-grey shales, rather silicious 
at the top E 5b E m 10 0 
** Compact, dark greenish-grey silicious shales ; dos a Matte (shaly 
sandstone) a vi ; 1 3 
* Brownish, earthy shales, passing down into whitish um and Dur 
mottled shales As 568 eee 10 0 
** Thin-bedded, fine-grained, greenish-grey drums with small specks of 
black and silvery mica 6 0 
* Greenish-grey and drab shales, chiefly batty, but with some thin 
silicious bands s: ai 156 tet ... 12 to 15 0 
From this point southwards these shales with quartzite bands are 
found to be resting sometimes on quartzite and at others on limestone 
(of the next lower group), and extend southwards as a narrow belt almost 
to Nundycotecoor, cropping out at low angles from under the truer 
limestone beds of the Koilkoontlas, while they are not distinguishable 
from these by any well-marked line of demarcation. Towards the 
bottom the shales are found to be of white, pale-grey, greenish, 
and reddish colors, looking in some respects like another set of shales 
(Owk shales) belonging to the next lower limestone series. 
A similar passing down of limestone beds by flags and shales 
to quartzites occurs on the opposite (left) side of the Kistnah, some 
distance to the west, in the neighbourhood of the villages of Pedda 
Duggada, Goodium, and Pedda Murroor, where a well-marked but 
very low-scarped outcrop of the harder limestones, shales, and for 
part of the distance quartzites, is seen winding about between the three 
villages: the grey and dirty greyish green sub-earthy shales, showing 
very strong in the high banks of the river south of P. Murroor, 
though only thinly towards P. Duggada. The quartzites are thinning 
out at Goodium and eventually disappear altogether to the south,
