Stratigraphy
| Formation: | Yorktown | ||||
| Stratigraphic resolution: | formation | ||||
| Stratigraphy comments: Local section name: Goldsboro. Basinal/regional section name: Wayne.
No specific lithostratigraphic details or stratigraphic relationships provided in text beyond the following: The beds assigned to the Yorktown are grouped for convenience into units lettered A to F, A being the lowest and F being the highest. Collections from Greene county appear to derive from Unit E. Unit E presumably falls within zone 2 of the Yorktown Fm (Gardner 1943). How this equates to the lithostratigraphic members applied in Ward (1992) is unclear. While older literature assigns the Yorktown Formation to the Late Miocene, a late Early Pliocene-Late Pliocene age is assigned to the collection following Ward (1992). Furthemore as the collection is derived from the upper zone of the formation a Late Pliocene age is assigned. | |||||
