Sedimentary rocks are a rock type that are formed in low-temperature and low-pressure environments through the compaction and solidification or precipitation (cementation) of sediments, rock fragments and minerals that have been transported and deposited on the surface of the Earth. The majority of these rocks were deposited during specific geologic time periods: The Precambrian (3800 to 570 million years ago), the early Paleozoic (570 to 410 million years ago), and the middle to late Mesozoic (205 to 66 million years ago). Sorted by name; initial letter means Igneous, Sedimentary or Metamorphic rocks.. A I Andesite – an intermediate volcanic rock M Anthracite – a form of hard coal B S Banded iron formation – a fine grained chemical sedimentary rock composed of iron oxide minerals S Bauxite – the main ore of aluminium.It is mostly aluminium oxide. They are deposited over time, and often show layers which can be seen in cliffs. Sedimentary rocks are formed at the earth's surface by the accumulation and cementation of fragments of earlier rocks, minerals, and organisms or as chemical precipitates and organic growths in water (sedimentation).This process causes clastic sediments (pieces of rock) or organic particles to settle and accumulate, or for minerals to chemically precipitate from a solution. Deutsch: Sedimentgesteine. Sedimentary rocks are types o rock that are formed bi the deposeetion o material at the Yird's surface an within bodies o watter.

Sedimentary rock Wikiversity ( geology ) One of the major groups of rock that makes up the crust of the Earth ; formed by the deposition of either the weathered remains of other rocks, the results of biological activity, or precipitation from solution . Around 70-80% of rocks on land are sedimentary. Iron-rich sedimentary rocks are sedimentary rocks which contain 15% or more iron.However, most sedimentary rocks contain iron in varying degrees.

Sedimentary rocks are rocks formed from sediment. Contents.
Español: rocas sedimentarias. Sedimentary rock is made of sediments which are particles that can be carried through liquid flows. Sedimentary basins form primarily in convergent, divergent and transform settings.Convergent boundaries create foreland basins through tectonic compression of oceanic and continental crust during lithospheric flexure.Tectonic extension at divergent boundaries where continental rifting is occurring can create a nascent ocean basin leading to either an ocean or the failure of the rift zone.
Sediments are usually formed from matter which falls to the bottom of oceans and lakes. Jump to navigation Jump to search. Igneous rock formed from lava that has become solid on the outside of the Earth is called extrusive igneous rock. Sedimentary rock, rock formed at or near the Earth’s surface by the accumulation and lithification of sediment (detrital rock) or by the precipitation from solution at … Other types of rock are igneous rock and metamorphic rock. Igneous rock (derived from the Latin word ignis meaning fire), or magmatic rock, is one of the three main rock types, the others being sedimentary and metamorphic.Igneous rock is formed through the cooling and solidification of magma or lava.The magma can be derived from partial melts of existing rocks in either a planet's mantle or crust. From Wikimedia Commons, the free media repository. Français : roches sédimentaires. Its name is from 'morph' (meaning form), and 'meta' (meaning change). This … 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 … Subcategories. This can happen because of the eruption of a volcano . They are created at or around the surface of the earth. Русский: Осадочные породы. Sedimentary rock is part of WikiProject Geology, an attempt at creating a standardized, informative, comprehensive and easy-to-use geology resource. This list may not reflect recent changes . Sedimentary rocks are one of the three different rock types.
