The lower member is characterized by thin bedding, stromatolites, gypsum pseudomorphs, intraclasts, and mud cracks. The rocks typically are laminated micrite and pelmicrite.For example, a limestone comprising pellets in a mud matrix is called a ‘pelmicrite’, and a limestone comprising shell fragments with a sparry calcite cement is a *‘biosparite’. It is possible to combine the prefixes of several allochems where appropriate, e.g. ‘oobiosparite’. Carbonaceous sediments and rocks.

Limestone ( calcium carbonate CaCO3) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of CaCO3. Limestone forms when these minerals precipitate out of water containing dissolved calcium.ABSTRACT. Limestones are divisible into eleven basic types, which are relatively easy to recognize both in the laboratory and in the field. These rocks are made up of three constituents: (1) allochems, evidently transported or otherwise differentiated carbonate bodies; (2) 1–4-micron microcrystalline calcite ooze matrix, and (3) coarser and ...
