Paleocoordinates:58.5° South, 101.1° East
Basis of coordinate:stated in text
Geographic resolution:outcrop
Time
Period:Triassic Epoch:Late/Upper Triassic
Stage:Norian 10 m.y. bin:Triassic 4
Key time interval:Norian
Age range of interval:228.00000 - 208.50000 m.y. ago
Stratigraphy
Formation:Mount Crosby
Stratigraphic resolution:bed
Stratigraphy comments: Purdy & Cranfield (2013) reported an unpublished SHRIMP date of 226±2 Ma for the Brisbane Tuff.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.

Environment:lacustrine - small Tectonic setting:rift
Geology comments: 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
