| USGS #M3869 - Pittsburg Bluff Formation | Moore E. J. (1976) | Pittsburg | Near top of formation. The Pittsburg Bluff Formation conformably overlies the Keasey Formation (late Eocene and early Oligocene) and is conformably overlain by the Scappose Formation (late Oligocene and early Miocene). Parts of the formation are lithologically similar and therefore the stratigraphic position of exposures are sometimes uncertain. The estimated thickness for the entire formation is 200 ml the thickest continuous section of the formation is 100 m thick. | sandstone | 28.1 - 23.03 Ma Cenozoic |
