Is calcite limestone? | AnswersDrive

Limestone. Limestone is a sedimentary rock, composed mainly of skeletal fragments of marine organisms such as coral, forams and molluscs. Its major materials are the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO3). About 10% of sedimentary rocks are limestones.

Calcite - Wikipedia

Etymology. Calcite is derived from the German Calcit, a term coined in the 19th century from the Latin word for lime, calx (genitive calcis) with the suffix -ite used to name minerals. It is thus etymologically related to chalk.. When applied by archaeologists and stone trade professionals, the term alabaster is used not just as in geology and mineralogy, where it is reserved for a variety of ...

Calcite - Wikipedia

Calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (CaCO 3).The Mohs scale of mineral hardness, based on scratch hardness comparison, defines value 3 as "calcite".. Other polymorphs of calcium carbonate are the minerals aragonite and vaterite.Aragonite will change to calcite over timescales of days or less at temperatures exceeding 300 °C, and vaterite is even ...

Geochemical constraints on the origin of calcite .

Calcite from large veins (5–50 cm wide) is characterized by radiogenic 87 Sr 86 Sr ratios (0.70887–0.70915) and low δ 13 C-values (−8.0 to −2.5‰, PDB), relative to host Viola limestone. Such isotopic compositions demonstrate that the fluids responsible for the formation of the large veins were enriched in 87 Sr and depleted in 13 C, relative to the host limestone.

Limestone is a sedimentary rock composed of calcium carbonate, plus calcium and/or magnesium. It is formed when layers of minerals (particularly calcite), fine sediment, and the skeletons and shells of marine organisms undergo lithification. Terrestrially-formed limestone is known as travertine.
