WebThis succession passes laterally into one where mudstones are dominant, assigned to the Tarporley Siltstone Formation. In the Nottingham area, the base of the unit is unconformable and is marked by a patchily distributed basal conglomerate up to 1m thick with a strong calcareous cement (Howard, 2003; Howard et al., in press). 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. Meer weergeven The Melbourne Formation is a geologic formation in Victoria, Australia.

WebSiltstone is a sedimentary rock composed mainly of silt-sized particles. It forms where water, wind, or ice deposit silt, and the silt is then compacted and cemented into a rock. Silt accumulates in sedimentary basins throughout the world. It represents a level of current, wave, or wind energy between where sand and mud accumulate.
