Geography
| Country: | Australia | State/province: | Queensland |
| Coordinates: | 27.6° South, 152.8° East (view map) | ||
| Paleocoordinates: | 58.6° South, 101.2° East | ||
| Basis of coordinate: | based on nearby landmark | ||
| Geographic resolution: | outcrop |
Time
| Period: | Triassic | Epoch: | Late Triassic |
| Stage: | Norian | 10 m.y. bin: | Triassic 4 |
| Key time interval: | Norian | ||
| Age range of interval: | 227 - 208.5 m.y. ago |
Stratigraphy
| Formation: | Blackstone | ||||
| Stratigraphic resolution: | group of beds | ||||
| Stratigraphy comments: Purdy & Cranfield (2013) reported an unpublished SHRIMP date of 226±2 Ma for the Brisbane Tuff. Therefore, the Blackstone Formation may be considered younger than 226 Ma in absolute age. Thus, the Ipswich Coal Measures above the Brisbane Tuff, which is to say, the succession from the Mount Crosby Formation to the top of the Blackstone Formation must now be considered Norian. | |||||
Lithology and environment
| Primary lithology: | lithified mudstone | ||
| Lithology description: Plant-rich mudstone | |||
| Environment: | pond | Tectonic setting: | rift |
| Geology comments: Interbedded sandstones and mudstones accumulated on levees bordering channels and graded laterally into floodplains where carbonaceous mudstones accumulated with thin crevasse splay sandstone beds.
Ipswich basin; transtensional rift in intermontane setting. Basin geometry affected by strike-slip movement along West Ipswich fault. Ipswich coal measures deposited near end of rifting phase. | |||
Taphonomy
| Modes of preservation: | adpression |
| Size of fossils: | macrofossils |
