Miocene 5.333 - 23.03 Ma ID: 1411565 | Spirit Lake pluton |
Oligocene - Eocene 23.03 - 56 Ma ID: 2824899 | Eocene-Oligocene volcanic rocks Age: Paleogene (23.03 - 56 Ma) Stratigraphic Name: Sanpoil Volcanics Description: Predominantly light-green, bedded andesite breccia with interbedded andesite and basalt flows, mudflows, and tuff beds; becomes more tuffaceous near top of unit. Includes tuffaceous and arkosic sandstone, shale, and carbonaceous shale beds in central and southern Cascade Mountians. Rhyodacite and quartz latite flows in northwestern Ferry County. Comments: Percentage of dacite thought to be andesite in the field; predominate over basaltic and rhyolitic rock (Warren, 1941). Large flows in Ferry County mostly dacite and andesite (Stoffel and others, 1991).
