46 PRIMARY OR PALASOZOIC ROCKS.—CASE X. 
Note.—A white, light-yellow, often banded sandstone, composed 
entirely of very fine, siliceous grains, overlies, in very thick beds, the 
Silurian rocks on the Coliban, in the neighborhood of Kyneton. Inter- 
stratified, thin beds of very coarse conglomerate, or puddiug-stone, 
frequently occur ; but fossils seem to be entirely absent. ‘The sandstone 
has been used in several buildings in Kyneton and the neighborhood. It 
is soft and easily worked, but cannot be procured of uniform color in 
large quantities; and, though it sometimes seems to harden on exposure, 
it is very liable to exfoliate, and is, therefore, not a good building stone. 
The quarries are now abandoned. ‘The Tertiary (Newer Pliocene) 
gold-bearing gravel beds overlie it in several places. The basalt, which 
overlies both, seems to have caused an alteration into hard, coarse quartz 
grit, numbers of large angular pieces of which are scattered round the 
respective boundaries.
