Stratigraphy
Formation:Gatun Member:middle Gatun
Stratigraphic resolution:bed
Stratigraphy comments: LITHOSTRATIGRAPHY: From middle part of the Gatun Formation. The Gatun Formation is sibdivided into three faunal zones (proposed by Thomson and Keen, 1946): lower, middle, and upper. AGE: Late Miocene, on the basis of microfossil biostratigraphy (see Collins and Coates, 1999), refined by enterer to Tortonian based on more recent dating (Hendy, 2012). Sr dating for nearby sections indicates an age of approximately 10.1 Ma (Hendy, unpublished data). STRATIGRAPHIC POSITION: Turritella-bearing marly siltstone.
