Nov 20, 2015· Limestone Classification Limestone isa sedimentary stone with 50% by weight calcite or calcium carbonate (CaCO3) content.However, commercial limestone usually has more than 50% calcium carbonate. Limestone is a “clastic” sedimentary stone.

Get PriceTravertine, tufa, caliche, chalk, sparite, and micriteare all varieties of limestone. Limestone has long fascinated earth scientists because of its rich fossil content. Much knowledge of the Earth’s chronology and development has been derived from the study of fossils embedded in limestone and other carbonate rocks. Limestone also has considerable commercial importance.
Get PriceMay 10, 2013· If the limestone also contains a minor element such as skeletal fragments, then it is called a skeletal-oolitic limestone. Two of the most widely used classifications are those of Folk (1959,1962) and Dunham (1962).
Get PriceSedimentary rock - Sedimentary rock -Classification of sandstones: There are many different systems of classifying sandstones, but the most commonly used schemes incorporate both texture (the presence and amount of either interstitial matrix—i.e., clasts with diameters finer than 0.03 millimetre—or chemical cement) and mineralogy (the relative amount of quartz and the relative abundance ...

Get PriceLimestone is defined by these two criteria: it is a sedimentary rock (1) and it is composed of calcium carbonate (2). There are other rocks that are composed of calcium carbonate. Carbonatite is a rare type of igneous rock and marble is a common metamorphic rock.
Get PriceMar 01, 1992· The most widely used classifications of limestones are now thirty years old and our appreciation of the diagenetic effects on limestone textures is now much greater. A revision of the classifications of Dunham (1962) and Embry and Klovan (1971) is offered and new “diagenetic” categories are proposed.

Get PriceLimestones 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 clearer sparry calcite, which in most rocks forms as a simple ...
Get PriceLimestoneis a carbonate sedimentary rock that is often composed of the skeletal fragments of marine organisms such as coral, foraminifera, and molluscs.Its major materials are the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO 3).A closely related rock is dolomite, which contains a high percentage of the mineral dolomite, CaMg(CO 3) 2.
