A large percentage of the calcite in rocks was deposited in sedimentary environments; consequently, calcite is a constituent of several diverse sediments, sedimentary rocks, and their metamorphosed products. A minor amount of the Earth’s calcite is of magmatic (i.e., igneous) origin; it is the chief constituent of the rare rock called ...

For sediment to become sedimentary rock, it usually undergoes burial, compaction, and cementation. Clastic sedimentary rocks are the result of weathering and erosion of source rocks, which turns them into pieces—clasts—of rocks and minerals. They are most often transported by water and deposited as layers of sediment.There are three main types of rocks: sedimentary, igneous, and metamorphic. Each of these rocks are formed by physical changes—such as melting, cooling, eroding, compacting, or deforming —that are part of the rock cycle.

Aeolian, sometimes spelled eolian or œolian, are deposits of windblown sediments. Since wind has a much lower carrying capacity than water, aeolian deposits typically consist of clast sizes from fine dust to sand [ 52 ]. Fine silt and clay can cross very long distances, even entire oceans suspended in the air.

Calcarenite is a clastic limestone consisting predominantly of sand-grade (1/16 to 2mm in diameter) calcitic or aragonitic particles (allochems, Folk, 1959); it is a consolidated carbonate sand. Grabau (1904) introduced this term as calcarenyte in his genetic classification of sedimentary rocks to convey the basic calcareous composition, …Clastic or detrital sedimentary rocks are made from pieces of bedrock, sediment, derived primarily by mechanical weathering. Clastic rocks may also include chemically weathered sediment. Clastic rocks are classified by grain shape, grain size, and sorting. Chemical sedimentary rocks are precipitated from water saturated with dissolved minerals.Other limestone that consists largely of the skeletal remains of marine organisms is considered bio-clastic, a cross between an organic and a detrital sedimentary rock.
