Limestone is a non-clastic sedimentary rock consisting of more than 50% calcite (a calcium carbonate mineral, CaCO3). Limestone is mostly a biological rock that forms in clear, warm, and shallow marine waters. Limestone exists in various types and colors.The characteristics and distinguishing features of clastic sedimentary rocks are summarized in Table 6.2. Mudrock is composed of at least 75% silt- and clay-sized fragments. If it is dominated by clay, it is called claystone. If it shows evidence of bedding or fine laminations, it is shale; otherwise it is mudstone. Coquina is a sedimentary rock composed almost entirely of sand-size fossil debris. The fossils are usually mollusk or gastropod shells and shell fragments. Brachiopod, trilobite, coral, ostracod and other invertebrate shell debris is present in many coquinas.

How Non-Clastic Sedimentary Rocks are Formed: Formed by chemical precipitation from a concentrated solution in water as salt, gypsum, …Classification of Sedimentary Rocks (Part 2) Non-clastic Texture. Non-clastic rocks have chemical or organic origins. Names of non-clastic rocks are based on their compositions. • A calcite-rich rock with many fossils is called a fossiliferous limestone. • Microcrystalline quartz is called chert. The red variety of chert is called jasper. Characteristics of sedimentary rocks are described in Pellant p. 38-41and 44-45; Marshak, p. 176-186. Texture: Sedimentary rocks may have clastic (detrital) or non-clastic texture. Clastic sedimentary rocks are composed of grains, fragments of pre-existing rocks that have been packed together with spaces (pores) between grains. TheseDolomite (also known as "dolostone" and "dolomite rock") is a chemical sedimentary rock that is very similar to limestone. It is thought to form when limestone or lime mud is modified by magnesium-rich ground water. The specimen shown above is about four inches (ten centimeters) across. Clastic sediment grains can be round, angular, or in-between (subangular or subrounded). Breccia is a clastic sedimentary rock that by definition consists largely of angular grains of pebble size or larger. Conglomerate, another sedimentary rock, consists largely of rounded grains of pebble size or larger. The schematic diagram below shows ... Limestone is a sedimentary rock made primarily from calcium carbonate, usually in the form of calcite and aragonite. Its grains vary in size and can consist of a variety of materials including shells, coral, and mud. It is typically off-white to gray in color and usually forms in shallow marine environments. ...
