Lithology and environment
Primary lithology: | sandstone | ||
Includes fossils? | Y | ||
Lithology description: The c.200 m thick basal unit is dominated by polymict, ortho- and paraconglomerates interbedded with coarse-grained, quartzose sandstones and minor siltstones and is assigned to the Tyers Conglomerate. This locality has discontinuous conglomerate lenses. | |||
Environment: | terrestrial indet. | Tectonic setting: | rift |
Geology comments: The Gippsland Basin is a roughly east-west orientated rift and epicratonic sag basin located along the southeastern margin of Victoria, Australia. The basin was initiated in the latest Jurassic or Early Cretaceous as rifting propagated along a roughly west-east axis between Austrailia and Antarctica. |
