Florentine Synclinorium, Tasmania (Ordovician of Australia)

Also known as Florentine Synclinorium, Tasmania, Australia

Where: Tasmania, Australia (42.0° S, 146.0° E: paleocoordinates 10.6° N, 166.4° W)

• local area-level geographic resolution

When: Florentine Valley Limestone Formation (Junee Group), Lancefieldian (484.3 - 474.9 Ma)

• Junee Group

• formation-level stratigraphic resolution

Environment/lithology: shoreface; lithified, glauconitic, calcareous sandstone and siltstone

• Lithology varies somewhat with locality and stratigraphic position within the formation; lithology generally described as a mixture of quartzose and calcareous siltstone, impure nodular limestone, chert, and minor glauconitic shale. Represents the base of a transgressive sequence that continues into overlying Gordon Limestone Group; base in most areas is coarse quartz sandstone with worm borrows and snails, ripple marks, load casts, and trough cross-bedding.

Size classes: macrofossils, mesofossils
