FIGURE 3: Correlation of the Milky River Formation at the Sandy Ridge stratigraphic section with the North Pacific diatom zonation based on data of diatom stratigraphy indicating a latest Miocene to early Pliocene age (modified from Gladenkov 2003, 2006). Q— Quaternary. a–c—subzones. Diatom zonation of Barron & Gladenkov (1995) for the last 8 myr correlated to the geochronologic time scale of Berggren et al. (1995).
