Stratigraphy
| Formation: | Astoria | ||||
| Stratigraphic resolution: | bed | ||||
| Stratigraphy comments: Unknown member. 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; theya re faulted and exposures are interupted by volcanic rocks and slides. The maximum thickness of any exposure is 25 feet. | |||||

| Includes fossils? | Y |
| Lithology description: Strata exposed consist shale varying in silt and sand content, siltstone, fine-grained sandstone with varying amounts of silt, coarse-grained sandstone, conglomerate, and tuff. Calcareous silty shale and fine-grained silty sandstone generally predominate. | |
| Environment: | coastal indet. |
| Geology comments: Astoria Formtaion is faulted and interupted in exposure by volcanic rocks and land slides. | |
