13. A light blue limestone, argillaceous and compact, weathering rugose 
like frosted glass, but without losing its fine, lustreless, clay-like, pale blue colour. 
It contains many remains of fossils in a bad state of preservation,... 30 ft. 
A fault from N. N. W.—S S.H.; downthrow 8. W. The fault is met near 
the end of the spur by another running W. 8. W.—H. N.H. The end of the 
spur, detached, as it were, by these two faults, strikes 8. H.—N. W. and dips 
N. H. 20°. The rock of this detached bed is a shaly limestone; the fossils are 
small and ill-preserved ; they occur in patches, one or two feet of the bed pre- 
senting a great number of remains, whilst hardly a trace of organisms is to be 
seen for some yards, It is about 50 feet thick,..................0.:see eee 50 ft. 
Another fault from N, N. W.—S. 8S. E.; downthrow 8S. W. The effect of 
this fault has been to bring up again the bed of Zeeawan limestone, and we 
therefore have the following bed to the N. H. of the fault. 
14, A coarse micaceous marly slate, without fossils, and passing gradually 
upwards into sandy shales of a dark brown colour and containing Producti, 
Orthide and Spirifers in a very bad state of preservation. These dark shales 
are identical in appearance and in some of their fossils with the brown shales 
of the Zeeawan bed, but the Bryozoa, so extensively developed in other 
localities, appear to be totally absent, and some small bivalves, which are 
found in the Weean bed and have not been seen in the Zeeawan bed, were 
discovered here,* These differences however may be easily accounted for by a 
difference of depth of the sea at the time the Zeeawan limestone and shale 
were deposited. The sandy and coarse micaceous slates seem to indicate a 
shallow sea with a drifting current on a shelving coast, a physical arrancement 
which may be a tolerable habitat for the large Brachiopoda, but unsuitable to 
the delicate Bryozou. 
This Zeeawan bed is succeeded by a shaly limestone, similar to that 
which is seen before the fault, that is to say Weean limestone. It 
has a well marked cleavage, due probably to its argillaceous impurities, 
and this cleavage is not unfrequently more conspicuous than the stra- 
tification. 
The end of the spur is, like the preceding spur, cut off by a 
transverse fault W. S. W.—E. N. EH. and the detached end dips 
H. N. HE. 20°, whilst the body of the spur, above the transverse fault, 
dips’ H. §. EH. 20°, the cleavage noted above dips N. W. 70°. 
The thickness of these two beds together is about 100 feet; they form the 
whole of the spur above the village of Koonmoo, ..........:.s...:.se eee 100 ft. 
28. Above Koonmoo, in the angle formed by the divergence 
of the two arms of the spur, is a spring with a Zyarat called Shokim. 
* A similar mixture of Zeeawan and Weean fossils is found in some parts of 
the Rotta Roh in the Punjab. See Chapter III. para. 60.
