Incidental
Unconsolidated > MarlFreshwater carbonates, often referred to as marls in the literature, are scattered over much of the State. In southern Florida, freshwater carbonates are nearly ubiquitous in the Everglades. These sediments are buff colored to tan, unconsolidated to poorly consolidated, fossiliferous carbonate muds. Sand, silt and clay may be present in limited quantities. These carbonates often contain organics. The dominant fossils in the freshwater carbonates are mollusks.
Unconsolidated > Peat (Bed)Organics occur as plant debris, roots, disseminated organic matrix and beds of peat.
Unconsolidated > Coarse-detrital > Gravel

Comments | Unit descriptions combine Qal, Qbd, Qtr and Qu all into one group 'undifferentiated sediments'. Tried to describe each unit separately as best as possible. |
