Calcite, limestone and marble Earth Sciences
2021-5-5 Limestone is a rock made of calcite. Most limestone is grey, but all colours of limestone from white to black have been found. Scientists test natural rock to see if it is limestone by pouring cold diluted hydrochloric or sulphuric acid (10% solution or vinegar) on it.

Limestone: Mineral information, data and localities.
Limestones are formed by either organic or inorganic processes, and may be detrital, chemical, oolitic, earthy, crystalline, or recrystallized; many are highly fossiliferous and clearly represent ancient shell banks or coral reefs. Limestones include chalk,

2019-11-22 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 less stable. Limestone

2021-4-21 Limestone is a sedimentary rock primarily made from the mineral Calcite. Limestone contains amounts of silica in forms of chert and flint, in quantities that may vary from rock to rock. Pure limestone is almost white; due to impurities, such as clay sand, but many limestones exhibit different colors, especially on weathered surfaces. The impurities in Limestone will sometimes become very ...

Limestone. Limestone is a sedimentary rock composed mostly of the mineral calcite and comprising about 15% of the Earth’s sedimentary crust. It is a basic building block of the construction industry (dimension stone) and a chief material from which aggregate, cement, lime and building stone are made. 71% of all crushed stone produced in the U.S. is either limestone or dolomite.
