58 TERTIARY OR CAINOZOIC AND RECENT ROCKS.—CASE XI, 
4. OLAY. Map No. R (A 4). 
Section 75, Redesdale, banks of 
Campaspe River. } sheet 13 
N.E. 
Contains fragments of charcoal, and 
occurs overlying the ordinary quartz 
pebble cement, and underlying the newer 
basalt. A tunnel has been driven into 
it, from which a good spring of mineral 
water issues.’ No gold was obtained. 
5. BLACK, ARGILLACEOUS Rock. 
Map No. Ra 10. 
Lot 4, section 22, Bulla-bulla, 
4 sheet 7 N.E. 
Occurs underlying post- Tertiary 
basalt, and resting on Tertiary, quartz- 
ose conglomerate. 
6. Cray, with Granitic DE- 
TRITUS. Map No. R (a5). 
S.W. of Baynton’s Station. 
3 sheet 5 N.W. 
Occurs, resting on granite, in yery 
hard andthick, horizontal beds, cropping 
out in the banks of tributaries of the 
Jew’s Harp Creek. 
7. LIMESTONE. 
Duck Ponds. 
and 24 N.E. 
Fresh-water limestone. It yields a 
good building lime, and may be made 
into cement, when mixed with a proper 
proportion of clayey matter; the best 
adapted for this purpose is a decom- 
posed basalt, from the Older Voleanic 
rocks. Higher up the Duck Ponds 
Creek, wells have been sunk, showing 
the following section :—

8. ĪMPURE, Siticzous LIME- 
STONE. Map No. R 11, 
Lot 1, section 7, Doutta- Galla. 
4 sheet 1 N.W. 
Occurs under newer basalt in con- 
cretionary nodules and layers. 
9. WHITE QUARTZITE. 
Keilor. 4 sheet 1 N.W. 
Under newer basalt. This rock forms 
a marked feature in many places along 
the banks of the Saltwater River, 
where it occurs in patches and lines of 
whitish looking stones, contrasting 
strongly with the grey, rocky escarp- 
ment of the basalt, immediately above it. 
10. Quartz Rock. 
Deep Creek, Hurdy-gurdy, West- 
ern Port. 
Containing rounded, transparent peb- 
bles of quartz.
