Limestone - Sedimentary rocks

Limestone is a very common sedimentary rock consisting of calcium carbonate (more than 50%). It is the most common non-siliciclastic (sandstone and shale are common siliciclastic rocks) sedimentary rock.Limestones are rocks that are composed of mostly calcium carbonate (minerals calcite or aragonite). Carbonate rocks where the dominant carbonate is dolomite (calcium magnesium carbonate) are ...

limestone | Characteristics, Uses, & Facts | Britannica

Limestone has two origins: (1) biogenic precipitation from seawater, the primary agents being lime-secreting organisms and foraminifera; and (2) mechanical transport and deposition of preexisting limestones, forming clastic deposits. Travertine, tufa, caliche, chalk, sparite, and micrite are all varieties of limestone. Limestone has long fascinated earth scientists because of its rich fossil ...

Carbonate Sedimentary Rock Classification

Two carbonate classification systems are in common use today, one by R.L. Folk and the second by R.J. Dunham . The Dunham system is based on depositional texture (that is, the amount of matrix surrounding the grains at the time of deposition). It uses such names as mudstone, wackestone, packstone, grainstone, and boundstone.

Indiana Limestone | Indiana Geological & Water Survey

Indiana Limestone, which is a Mississippian-age grainstone of very uniform texture and grade, has gained world-wide acceptance as a premier dimension stone. The Salem Limestone, which is the geologic formational name for this carbonate unit, crops out in a belt that trends southward from Stinesville in Monroe County to Bedford in Lawrence County.

Chapter 5 LIMESTONES - MIT OpenCourseWare

2.5 Most of the calcite precipitated by marine organisms contains a certain percentage of magnesium. Such calcite is called magnesian calcite; it's subdivided into low-magnesium calcite and high-magnesium calcite at 4% MgCO3 content. Generally the more advanced the organism, the less magnesium in the calcite.In the case of red algae, an important sediment producer, the

Folk limestone classification - Oxford Reference

A widely used classification of carbonates, based on the type of particles and the nature and proportion of the matrix and/or cement present. In his original classification Robert L. Folk defined three main components to limestones. These are allochems, comprising various grains and particles; micrite (microcrystalline calcite mud matrix); and sparite (sparry calcite cement).

Dunham classification |

Dunham classification A widely used limestone classification, proposed by Robert Dunham in 1962, which divides limestones on the basis of their texture and mud content. For limestones which retain their original, depositional texture, the main subdivisions are: lime mudstone (limestone with less than 10% grains in a mud-supported sediment); lime wackestone (limestone with more than 10% grains ...

Limestone is a type of a sedimentary rock that is found naturally in the earth's environment. The rock comprises primarily of chemical compound calcium carbonate (CaCO 3) in the form of calcite which is yet again a type of a mineral.It also contains other materials like quartz, clay minerals, pyrite, feldspar, and siderite amongst others.
