|Name||Trail Ridge sands|
Unconsolidated > Coarse-detrital > SandThe siliciclastics are light gray, tan, brown to black, unconsolidated to poorly consolidated, clean to clayey, silty, unfossiliferous, variably organic-bearing sands to blue green to olive green, poorly to moderately consolidated, sandy, silty clays.
Unconsolidated > Fine-detrital > ClaySand, silt and clay may be present in limited quantities.
Unconsolidated > Peat (Bed)Organics occur as plant debris, roots, disseminated organic matrix and beds of peat.
Unconsolidated > Coarse-detrital > GravelGravel occasionally is present in the panhandle.
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. These carbonates often contain organics. The dominant fossils in the freshwater carbonates are mollusks.
Unconsolidated > Fine-detrital > SiltSand, silt and clay may be present in limited quantities.
