NOTES ON QUARTZ REEFS, LIGNITE, CLAY, AND BASALT, 
NEAR KILMORE. 
By E. ]. Dunn , F.G.S., Director , Geological Survey. 
Leyden’s Paddock Reef. 
Leyden’s Paddock reef is situate about i| miles in a southerly direction 
from By lands Post-office, and is 1,600 feet above sea-level. The country 
rocks are grey and yellow slates and sandstones of Upper Silurian age.. 
The soil is grey. 
The reef is situate near the top of the Divide. The strike is north and 
south, dip 85 deg. W. It appears to be on an anticline, as the country 
dips west on the west side and east on the east side of the reef. The 
quartz is chertv and close-grained in character, and has a ferruginous stain. 
The pitch of the country is N. at 15 deg. Dip 20 deg. W. on one side of 
the reef and about the same angle east on the other side. The quartz, 
varies in thickness from 3 inches to 2 feet, and it is said to carry gold 
to the extent of* a few dwts. and a few loads are broken at the surface for 
a trial crushing. Depth of shaft 20 feet. The reef has been driven on 
northward 20 feet and southward 5 feet from the shaft. A Kilmore 
syndicate is prospecting this reef. 
Goldie, near Kilmore. 
Since my previous report a shaft has been sunk 120 feet to prospect for 
a western leg corresponding to the eastern leg which has been extensively 
worked and also for any other developments of auriferous quartz. The 
shaft is sunk through grey sandstones and slates of Upper Silurian age, but 
there are no fossils available to indicate the zone to which these beds 
belong. From the shaft a cross-cut has been driven east for 43 feet. At the 
bottom of the shaft the beds dip east for 3 feet, then west for 27 feet to 
the anticline or centre country. From centre country to- the east face is 
13 feet and the dip is about vertical. The pitch of the anticline is about 
20 deg. N. The trend of centre country is westward as in the bottom 
of the shaft it is about 10 feet further west than at the surface. A fault 
dipping 15 deg. W. cuts through the beds east of the shaft. There is a 
little quartz in the fault. 
The work so far done is of a negative character, but it has tested 
country below that in which the auriferous quartz was formerly worked. 
The shaft should be deepened to still further prospect this site; this would 
entail the erection of a small winch, as the water level has been reached. 
It also seems desirable that the east leg formerlv worked should be- 
prospected further north than the present end of the workings and below 
water level, as the shoot of gold formerly worked pitches north. There is 
a shaft 170 feet deep at this end and if it were unwatered, work might be 
done from it. 
Quartz and Other Rocks in Basalt, Kilmore. 
In the road cuttings near the gaol at Kilmore blocks of quartz and 
sandstone and smaller pieces that may be pebbles of quartz, granite, 
sandstone, &c., are abundantly disseminated through the basalt, which is 
somewhat vesicular as a rule. These blocks range downwards from over 
18 inches in length. The quartz and other foreign rocks are much fractured 
and altered, evidently by the heat of the molten basalt. 
Quartz pebbles and fragments are o-ccasionallv observed entangled in 
the basalt flows, but the Kilmore occurrence is unusual on account of the- 
size and abundance of foreign rocks.
