| 説明 | This is an exposure of the Shinarump Member, in the basal Chinle Formation (Upper Triassic). The Chinle is a multicolored, nonmarine unit consisting of coarse-grained siliciclastics (fluvial channel facies) and fine-grained siliciclastics (floodplain facies). Quartz-permineralized fossil wood is famously common in the Chinle Formation (for example, Petrified Forest National Park in Arizona).The Shinarump Member (also known as the Shinarump Conglomerate) here consists of sandstones and conglomerates. At Dinosaur National Monument, the unit is also known as the Gartra Member of the Chinle Formation.Stratigraphy: Shinarump Conglomerate (Shinarump Member), lower Chinle Formation, Upper TriassicLocality: outcrop north of Cub Creek Road, Dinosaur National Monument, northern Uintah County, northeastern Utah, USA (vicinity of 40° 25' 20.03" North latitude, 109° 11' 03.91" West longitude)------------See info. at:en.wikipedia.org/wiki/Dinosaur_National_Monument------------Geologic map of Dinosaur National Monument:pubs.usgs.gov/imap/1407/plate-1.pdf |
