Stratigraphy
| Formation: | Collinsville Coal Measures | Member: | Glendoo Sandstone | ||
| Stratigraphic resolution: | group of beds | ||||
| Stratigraphy comments: Glendoo Sandstone thought to be lateral equivalent of the middle part of the Gebbie Formation, most likely belonging to the upper Echinalosia maxwelli, E. davidi, or lower E. discinia brachiopod zones of Briggs (1998). These parts of the zones are correlated with the APP3.3 palynomorph zone. Laurie et al. (2016) dated zircons from the Rowan Formation in the Sydney Basin (in the underlying upper Echinalosia preovalis zone, or upper APP3.2) as 271.60 and 271.89 Ma, constraining its upper part to Roadian, given a Roadian-Wordian boundary around 266.9 Ma (Wu et al., 2020). Strata in Western Australia assigned to APP4.1 yielded U-Pb ages of 269.25 Ma or younger, constraining the upper boundary of APP3.3 to the late Roadian (Laurie et al. 2016). As a result, APP3.3 appears to fall entirely within the Roadian. | |||||
