DescriptionChinle Formation (Upper Triassic; just south of Split Mountain, Dinosaur National Monument, Utah, USA) 1 (48811268151).jpg |
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). At left & center is the Chinle Formation (Upper Triassic), 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 brown rocks at left are sandstones and conglomerates at the base of the Chinle Formation. This unit is called the Shinarump Member or Shinarump Conglomerate. At Dinosaur National Monument, the unit is also known as the Gartra Member of the Chinle Formation. At right is an eolian sandstone unit called the Glen Canyon Sandstone (Upper Triassic to Lower Jurassic). It's equivalent to the Navajo Sandstone (also known as the Nugget Sandstone). The Glen Canyon/Navajo/Nugget is a thick and widespread desert sand dune deposit, technically called an erg facies. 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.
