Stratigraphy
| Formation: | Torreya | ||||
| Stratigraphic resolution: | member | ||||
| Stratigraphy comments: STRATIGRAPHIC RELATIONS: From the Torreya Fm, which unconformably underlies the Chipola Fm (Middle Miocene). AGE: Early Miocene based on molluscan biostratigraphy. Also correlates with Hemingfordian (land mammal)), Miogypsina (foram) and Dizatom Zone I of Abbott (1978) biostratigraphic zones. STRATIGRAPHIC POSITION: From upper part of the Torreya Fm, above the Dogtown Mbr. | |||||
