Neogene
2.588 - 23.03 Ma



ID: 3186305
Cenozoic volcanic rocks

Age: Neogene (2.588 - 23.03 Ma)

Stratigraphic Name: Columbia River Basalt

Comments: Columbia Plateau

Lithology: Flood basalt(s); mafic volcanic rocks; basalt

Reference: Chorlton, L.B. Generalized geology of the world: bedrock domains and major faults in GIS format: a small-scale world geology map with an extended geological attribute database. doi: 10.4095/223767. Geological Survey of Canada, Open File 5529. [154]

Pliocene - Miocene
2.588 - 23.03 Ma



ID: 2850908
Tuffaceous sedimentary rocks and tuff

Age: Neogene (2.588 - 23.03 Ma)

Stratigraphic Name: Drewsy Formation; Rattlesnake Formation; Dalles Formation; Shutler Formation; Kern Basin Formation; Danforth Formation; Bully Creek Formation; Yonna Formation; Grassy Mountain Basalt; Chalk Butte Formation; Drip Spring Formation; Glenns Ferry Formation

Description: Semiconsolidated to well-consolidated mostly lacustrine tuffaceous sandstone, siltstone, mudstone, concretionary claystone, conglomerate, pumicite, diatomite, air-fall and water-deposited vitric ash, palagonitic tuff and tuff breccia, and fluvial sandstone and conglomerate. Palagonitic tuff and breccia grade laterally into altered and unaltered basalt flows of unit Tob. In places includes layers of fluvial conglomerate and, in parts of the Deschutes-Umatilla Plateau, extensive deposits of fanglomerate composed mostly of Miocene basalt debris and silt. Also includes thin, welded and nonwelded ash-flow tuffs. Vertebrate and plant fossils indicate rocks of unit are mostly of Clarendonian and Hemphillian (late Miocene and Pliocene) age. Potassium-argon ages on interbedded basalt flows and ash-flow tuffs range from about 4 to 10 Ma. Includes the Drewsey Formation of Shotwell and others (1963); sedimentary parts of the Rattlesnake Formation of Brown and Thayer (1966); an interstratified ash-flow tuff has been radiometrically dated by potassium-argon methods at about 6.6 Ma (see Fiebelkorn and others, 1983); Bully Creek Formation of Kittleman and others (1967); Dalles Formation of Newcomb (1966, 1969); Shutler Formation of Hodge (1932), McKay beds of Hogenson (1964) and Newcomb (1966) (see also Shotwell, 1956); Kern Basin Formation of Corcoran and others (1962); Rome beds of Baldwin (1976); parts of the (now obsolete) Danforth Formation of Piper and others (1939), Idaho Group of Malde and Powers (1962), Thousand Creek Beds of Merriam (1910); the Madras (or Deschutes) Formation, the "Simtustus formation" of Smith (1984), and the Yonna Formation (Newcomb, 1958). In areas west of Cascade crest, includes the Sandy River Mudstone and the Troutdale Formation of Trimble (1963) and the lower Pliocene Helvetia Formation of Schlicker and Deacon (1967)

Comments: Also includes Chalk Butte Formation (OR016), Drip Springs Formation (OR023; OR024), sediments of Captain Keeney Pass (OR153), Glenns Ferry Formation (OR154; OR155), and part of the Grassy Mountain Basalt (OR121). In northern half Umatilla River Basin (OR292) Miocene and Pliocene sedimentary rocks include poorly consolidated, thin, but extensive, siltstone, sandstone, and conglomerate locally interbedded with Saddle Mountains Basalt
