| 説明 | This outcrop is next to Split Mountain in Dinosaur National Monument, Utah, through which the Green River has erosionally carved a prominent canyon (off frame, to the left).The reddish-colored rocks are hematite-rich, fine-grained siliciclastics of the Moenkopi Formation (Triassic). Gypsum is common in parts of the Moenkopi.The yellowish and reddish shales at top are in the next unit down, the Park City Formation (Permian).Structurally, this is the southern flank of the Split Mountain Anticline, which strikes east-west and plunges westward. This is also the northern flank of the Jensen Syncline.Stratigraphy: Moenkopi Formation, Lower TriassicLocality: southern flanks of Split Mountain, Dinosaur National Monument, northern Uintah County, northeastern Utah, USA (40° 26' 36.83" North latitude, 109° 14' 59.59" 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 |
