Lithology and environment
Lithology description: The Locmany Member of the Rintoul Creek Formation consists of interbedded quartzose sandstones and fossiliferous siltstones. The lower portion of the Locmany Member contains a few thin, discontinuous, conglomerates and bituminous coal seams. The Locmany Member is the source of the majority of the fossils examined in this study. | |||
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. |
