Petrologist’s definition Calcarenite is a calcareous clastic sedimentary rock, formed by compaction and cementation of carbonate clasts of size between 0.06 and 2 mm. Dolomite. Although limestone is the dominant carbonate rock in most Phanerozoic sequences, dolomite is commonly a major constituent, especially in Paleozoic rocks (Garrels and Mackenzie, 1971).Some carbonate rocks are a mixture of calcite and dolomite, but most are relatively pure limestone or dolomite (Steidtmann, 1917).The standard test …Calcarenite is a carbonate rock. Calcarenite was originally named in 1903 by geologist Grabau when he was describing the stone by the size of the individual particles.

Calcilutite (also known as cementstone) [1] is a type of limestone that is composed of predominantly, more than 50 percent, of either clay-size or both silt-size and clay-size detrital (transported) carbonate grains. These grains consist either of fossil fragments, ooids, intraclasts, pellets, other grains, or some combination of them. Types of Rocks. The following is a list of rock types recognized by geologists. Any unique combination of chemical composition, mineralogy, grain size, texture, or other distinguishing characteristics can describe a rock type. Additionally, different classification systems exist for each major type of rock.Clastic (or detrital) rocks are made of clay, silt, sand, gravel, and/or boulders. These grains are usually made of silicate minerals (quartz, feldspar, mica, clay minerals, etc.) or rock fragments because most biochemical and chemical grains (see below) do not survive chemical weathering or extensive transport.; Coal is made of compressed plant debris …Limestone is a carbonate sedimentary rock that consists predominantly of calcite [CaCO 3 ].
