Stratigraphy
Formation:Tamiami
Stratigraphic resolution:formation
Stratigraphy comments: LITHOSTRATIGRAPHIC RELATIONSHIPS: From the Tamiami Formation, which unconformably underlies the Pinecrest Beds (=Pincrest Fm), and is correlative to the Choctawatchee Fm (=Jackson Bluff Fm) in Northern Florida and Yorktown Fm of North Carolina and Virginia. AGE: Miocene according to DuBar (1962), but assigned here to an Early Pliocene age on the basis of more recent publications. STRATIGRAPHIC POSITION: From unknown position within formation.
Lithology and environment
Primary lithology:phosphatic,yellow unlithified argillaceous marl
Secondary lithology:phosphatic,gray unlithified claystone
Includes fossils?Y
Lithology description: Along Shell Creek: argillaceous marls and calcareous clays; all beds are slightly to moderated consolidated, phosphatic, cream to yellowish in color and sparsely fossiliferous. Along Alligator Creek: clays, marls, sands, and a few thin limestones; most of the units, except the limestones, are only slightly consolidated, and nearly all are at least slightly phosphatic; colors range from gray through tan, cream and buff; sands, in general, are most common to the east with calcareous clays, limestones, and marls predominant in the west
Environment:marine indet. Tectonic setting:passive margin
Geology comments: Fine grained clastics such as clays and argillaceous limestones of the Tamiami are considered brackish water lagoon or bay deposits. Along Alligator Creek and in pits in Acline, the formation is represented by a phosphatic quartz sand containing many specimens large barnacles and sand dollars, which is considered a shallow water, nearshore environment, possibly a submerged sandbar.
