| 説明 | Unconformities are surfaces of erosion and/or non-deposition of sediments. Types of unconformities include disconformities, nonconformities, and angular unconformities.Seen here is an unconformity representing about 165 million years worth of missing time. Brownish-colored gravel of Quaternary age has been deposited atop structurally-tilted grayish beds of Middle Jurassic age. The contact is a angular unconformity (= sedimentary over sedimentary, with tilted or folded layers below).Stratigraphy of tilted beds: Arapien Formation, Middle JurassicLocality: mouth of Salina Canyon, south-southeast of the town of Salina, Sevier County, central Utah, USA |
