Lithology and environment
| Primary lithology: | condensed,nodular,phosphatic grainstone |
| Includes fossils? | Y |
| Lithology description: "Cream coloured calcarenite with abundant phosphatic grains and nodules" | |
| Environment: | open shallow subtidal |
| Glacial or sequence phase: | transgressive |
| Geology comments: "The deposition of the Miria Formation began in the wake of a Late Maastrichtian marine transgression, resulting in quiet shelf deposits in the northern Carnarvon Basin...the unit has been condensed, with fragmentary fossil preservation indicating periods of higher water energy which winnowed the sequence" | |
