Stratigraphy
Geological group:Okeechobee Formation:Bermont Member:Holey Land
Stratigraphic resolution:member
Stratigraphy comments: STRATIGRAPHIC RELATIONS: From the Holey Land Mbr of the Bermont Fm, Okeechobee Grp, which is overlain by the Belle Glade Mbr. Correlative with the Flanners Beach Fm (North and South Carolina). THICKNESS: Varies between 3.5 and 15 m across areal extent. AGE: Middle Pleistocene. Based on uranium isotope dating the unit is dated as early middle Pleistocene, Aftonian. STRATIGRAPHIC POSITION: Checklist representative of entire member.
Lithology and environment
Primary lithology:shelly/skeletal poorly lithified sandy,calcareous "limestone"
Includes fossils?Y
Lithology description: SPECIFIC LITHOLOGY: Sandy (quartz), highly fossiliferous limestones (arenaceous biomicrudites and arenaceous crudites), often indurated, sometimes unconsolidated. LITHIFICATION: Poorly-lithified, based on figured specimens and facies description.
Environment:shallow subtidal indet.
Geology comments: ENVIRONMENT: Shallow subtidal carbonate; mangrove forests and intertidal mud flats, turtle grass beds, shallow-sand-bottom lagoons, coral reefs and bioherms.
