Stratigraphy
Geological group:Junee Formation:Florentine Valley Limestone
Stratigraphic resolution:formation
Stratigraphy comments: Junee Group
Lithology and environment
Primary lithology:current ripples,glauconitic lithified calcareous sandstone
Secondary lithology: siltstone
Environment:shoreface
Geology comments: 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.
