Stratigraphy
Geological group: | Cooper | Formation: | Ashley | ||
Stratigraphic resolution: | member | ||||
Stratigraphy comments: early Chattian, NP 24, 30 cm below contact with the overlying Chandler Bridge Formation; Ashley Formation is identified as Rupelian rather than its conventional assignment as Chattian by Weems et al. 2004
The Ashley Formation falls within calcareous nannoplankton zone NP24 [103], ranging from 29.6–26.8 Ma [12, 20]. The presence of the dinoflagellate Chiropteridium lobospinosum indicates a minimum age of 28.1 Ma [103, 104]. Together, these constraints imply a late Rupelian age (29.6–28.1 Ma) for the Ashley Formation, which is further supported by a strontium date of 29.1 Ma [105]. (Marx & Fordyce, 2015) |
