Stratigraphy
| Geological group: | Junee | Formation: | Florentine Valley Limestone | Member: | Mt. Field Siltstone |
| Stratigraphic resolution: | group of beds |
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. | |
