The Melbourne Formation is a geologic formation in Victoria, Australia. It preserves fossils dating back to the Ludlow epoch of the Silurian period.[1][2]
Description
[edit]
The Melbourne Formation, part of the Murrindindi Supergroup, is conformably overlain by the Humevale Formation and overlies the Yan Yean and Anderson Creek Formations. The formation comprises mainly thin-bedded siltstone and sandstones. Most beds show undisturbed Bouma sequences.[1]
