Summary
[edit]DescriptionPrecambrian-Cambrian nonconformity (Sawatch Sandstone over Pikes Peak Granite; Ute Trail, Manitou Springs, Colorado, USA) 3.jpg |
English: The rock record does not completely document Earth's history. In stratigraphic sections, missing time is represented by unconformities - surfaces of erosion and/or non-deposition of sediments. There are four types of unconformities: paraconformities, disconformities, nonconformities, and angular unconformities.
Seen here is the Precambrian-Cambrian unconformity at Manitou Springs, Colorado. The rocks in the upper part of the photo are Cambrian sandstones. The underlying rocks are part of the Pikes Peak Granite. About one-half a billion years is missing at the contact. Erosion surfaces such as this that have sedimentary rocks over igneous rocks are called nonconformities. Stratigraphy: Sawatch Sandstone (Upper Cambrian) over Pikes Peak Batholith (late Mesoproterozoic, 1.08 Ga) Locality: Ute Trail Outcrop - exposure along the northeastern side of old Ute Trail, adjacent to Fountain Creek, northwestern end of the town of Manitou Springs, west of Colorado Springs, western El Paso County, central Colorado, USA (38° 52’ 07.28” North latitude, 104° 55’ 28.36” West longitude) |
