GEOLOGY. 41 
Hi ' A p fterwards 1 went south of the camp, where on our road westward 1 I got a section like 
biT * a Mecjaloilon - The hmestone is mostly dolomitic, white or light grey, and less 
I ominous than (-=). I got crinoid stems in it. and a small Fee ten ; I could not say whether 
lower tnas or carboniferous. 
at ^ lay Kamhubar {same camp as on April 2nd).— Two and a half miles from Aktash, 
th a s l )ot where the stream from the Nezatash pass is joined by another flowing from 
a e sou th-east, there is a mass of greenstone in the shales, and east of that mass the shales 
t l! altered, evidently indicating tliat the outburst of the greenstone must have 
e n place after the deposition of the triassic shales. Looking north, the shales continue 
T* ! !r Ut a cou Pl e °f miles, composing the hills, wliich rise to about 3,000 feet above the valley. 
I I ) 1( north-west is a great mass of greenstone again, while a sharp ridge of limestone runs 
r °ugh the shales, coming from the west, and disappearing and broken up towards the east. 
u her on, the shales are seen to he overlain by reddish sandstones and shales, towards the top 
niueh alternating with greenish-grey beds ; and this series is again capped by a light-brownish 
,, of inconsiderable thickness. These last rocks and the limestones dip north by east, but 
the 
crumbling shales are very much contorted, mostly by the greenstone. 
The section from Aktash to the north is something like this : —

a number of pelecypod sections in the hmestone, which appear to belong to Megalo- 
U ‘ They were rather large, but otherwise not distinguishable. 
tfurthisp on, the shales were several times crossed by greenstone, and then followed the 
aded grey rock. The carboniferous limestone ridge runs from Aktash almost due eastward, 
c about 5 miles before reaching Kanshubar it turns gradually to south-east, still retaining 
lts great height.
