Stratigraphy
Formation:Eugene
Stratigraphic resolution:bed
Stratigraphy comments: Eugene Formation can be subdivided faunally: a lower unit correlating to the Keasey Fm, a middle unit correlating to the Gries Ranch Beds of WA, and a upper unit correlated with the Pittsburg Bluff Fm. Thickness of formation may be up to 15,000 feet, but probably around 5,000 feet. Most of the outcrops are scattered so it is difficult to estimate their relative stratigraphic placement
Lithology and environment
Primary lithology:tuffaceous,brown,gray,blue lithified sandstone
Secondary lithology:tuffaceous,brown,gray,blue siltstone
Includes fossils?Y
Includes fossils?Y
Lithology description: Tuffaceous and highly feldspathic sandstone or siltstone which is bluish-gray to olive when fresh and weathers to a buff or orange-brown color. Gray sandstone and siltstone beds may range from several to 50 feet in thickness and are interbedded with minor amounts of sandy sahel and clay shale, occasional beds of conglomerate, and thin lenses of gray or buff-colored volcanic ash
Environment:coastal indet.
