Stratigraphy
Geological group: | Hawthorn | Formation: | Peace River | ||
Stratigraphic resolution: | formation | ||||
Stratigraphy comments: STRATIGRAPHIC RELATIONS: From the Peace River Fm, Hawthorn Grp, which is overlain by the Bayshore Fm. Correlative with the St Marys and Shoal River Fms. THICKNESS: Varies between 100 and 200 m across areal extent. AGE: late Midde-early Late Miocene. Based on macrofossil biostratigraphy the unit is throught to represent the Serravallian-early Tortonian; here assigned to Serravalian. STRATIGRAPHIC POSITION: Checklist representative of entire member.
Previously Barstovian, but Missimer (1999) suggested that the Peace River Formation in Florida was likely deposited between 11-4.3Ma. The lower sequence is Tortonian, deposited between 11-8.5Ma, and the upper sequence is Zanclean and deposited between 5.2-4.3Ma |
Lithology and environment
Primary lithology: | very fine,medium,dolomitic,phosphatic lithified argillaceous sandstone |
Includes fossils? | Y |
Lithology description: SPECIFIC LITHOLOGY: Interbedded quartz sands, clays, and carbonates. Quartz sands are dominant, and are calcareous to dolomitic, phosphatic, very fine to medium grained, and poorly consolidated LITHIFICATION: Lithified, based on figured specimens. | |
Environment: | lagoonal/restricted shallow subtidal |
Geology comments: ENVIRONMENT: carbonate lagoonal/restricted shallow subtidal environment; shallow muddy sand lagoon and turtle grass beds. |
