sedimentary rock sequence
1sedimentary rock — Rock formed at or near the Earth s surface by the accumulation and lithification of fragments of preexisting rocks or by precipitation from solution at normal surface temperatures. Sedimentary rocks can be formed only where sediments are… …
2Sedimentary rock — Middle Triassic marginal marine sequence of siltstones (below) and limestones (above), Virgin Formation, southwestern Utah, USA Sedimentary rock are types of rock that are formed by the deposition of material at the Earth s surface and within… …
3Rock microstructure — includes the texture of a rock and the small scale rock structures. The words texture and microstructure are interchangeable, with the latter preferred in modern geological literature. However, texture is still acceptable because it is a useful… …
4Sequence stratigraphy — is a relatively new branch of geology that attempts to link relative sea level changes to sedimentary deposits. The essence of the method is mapping of strata based on identification of surfaces which represent time lines (e.g. subaerial… …
5sedimentary facies — Different, but contemporaneous and juxtaposed, sedimentary rocks. Terrigenous facies are accumulations of particles eroded from older rocks and transported to the depositional site. Biogenic facies are accumulations of whole or fragmented shells… …
6igneous rock — Any of various crystalline or glassy, noncrystalline rocks formed by the cooling and solidification of molten earth material (magma). Igneous rocks comprise one of the three principal classes of rocks, the others being metamorphic and sedimentary …

8Absaroka sequence — The Absaroka sequence was a cratonic sequence that extended from the end of the Mississippian through the Permian periods. It is the unconformity between this sequence and the preceding Kaskaskia that divides the Carboniferous into the… …
9List of geology topics — This is a list of all articles related to geology that cannot be readily placed on the following subtopic pages: Geology subtopics* Geologic time scale * List of compounds * List of earthquakes * List of elements by name * List of geology of… …
10Catskill Formation — The Devonian Catskill Formation (Dck) is the name given to a thick bedrock unit found in Pennsylvania and New York. It is at the top of the sedimentary rock sequence deposited in the Catskill Delta, known as the Catskill Clastic Wedge, which is a …
