Although no one basin classification scheme has been widely adopted, several common types of sedimentary basins are widely accepted and well understood as distinct types. Over its complete lifespan a single sedimentary basin can go through multiple phases and evolve from one of these types to another, such as a rift process going to completion ...
Examples of such basin classifications include intracratonic, rift, passive margin, strike-slip, forearc, backarc-marginal sea, fold and thrust belt, and foreland basins. [1] Sedimentary basin analysis is largely conducted by two types of geologists who have slightly different goals and approaches.
Sedimentary basins. Subcategories. This category has the following 3 subcategories, out of 3 total. ...
Sedimentary structures include all kinds of features in sediments and sedimentary rocks, formed at the time of deposition. Sediments and sedimentary rocks are characterized by bedding , which occurs when layers of sediment, with different particle sizes are deposited on top of each other. [ 1 ]
Idealized cross-section of Earth's lithosphere, including the relationship between cratons, shields and platforms (Abbreviations: cb=cratonic basin, LIP=large igneous province, MOR=mid-ocean ridge) In geology, a platform is a continental area covered by relatively flat or gently tilted, mainly sedimentary strata , which overlie a basement of ...
Uluru (Ayers Rock) is a large sandstone formation in Northern Territory, Australia.. Sedimentary rocks can be subdivided into four groups based on the processes responsible for their formation: clastic sedimentary rocks, biochemical (biogenic) sedimentary rocks, chemical sedimentary rocks, and a fourth category for "other" sedimentary rocks formed by impacts, volcanism, and other minor processes.
Basement rock is the thick foundation of ancient, and oldest, metamorphic and igneous rock that forms the crust of continents, often in the form of granite. [2] Basement rock is contrasted to overlying sedimentary rocks which are laid down on top of the basement rocks after the continent was formed, such as sandstone and limestone.
A structural basin is a large-scale structural formation of rock strata formed by tectonic warping of previously flat-lying strata into a syncline fold. They are geological depressions , the inverse of domes .
