Tillamook (UGSG 15301) - #42 (Moore, 1963) | Moore E. J. (1963) | Astoria | From unknown horizon. Astoria Formation has been used as a name for almost all of the marine middle Miocene sedimentary rocks of Washington and Oregon although these correlations are poorly constrained. The formation has been divided into three members: a lower sandstone, a shale, and an upper sandstone. These rocks form the northern limb of a syncline, the asis of which is exposed east of Astoria, and the syncline trends NE and plunges to the SW. The Astoria Formation is intermittently exposed; | "shale" | 15.97 - 11.608 Ma Miocene |
