Stratigraphy
Formation: | Keasey | Member: | Middle | ||
Stratigraphic resolution: | bed | ||||
Stratigraphy comments: Middle member includes 500 m of predominantly light gray highly tuffaceous siltstone and mudstone beds with occasional ash layers and calcaerous concretionary beds. The Keasey Formation consists of a maximum of 700 m of gray tuffaceous marine siltstone and massive mudstone discontinuously exposed in quaries, road and railway cuts, and along major drainages. The Keasey Fm overlies the late Eocene Cowlitz Fm, and underlies the Pittsburg Bluff Fm. Fm is subdivided into three informal members. |
