2024年12月6日 · Limestone is a sedimentary rock made of calcium carbonate (CaCO), usually in the form of calcite or aragonite. It may contain considerable amounts of magnesium carbonate (dolomite) as well. However, minor constituents of clay, iron carbonate, feldspar, pyrite, and quartz is also commonly present.

Limestone is a sedimentary rock composed primarily of calcite, a calcium carbonate mineral with a chemical composition of CaCO 3. It usually forms in clear, calm, warm, shallow marine waters. Limestone is usually a biological sedimentary rock, forming from the accumulation of shell, coral, algal, fecal, and other organic debris.
Limestone - Wikipedia
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.
Limestone: A Comprehensive Guide - Geology
Limestone is a sedimentary rock composed primarily of calcium carbonate (CaCO3) derived from the remains of ancient marine organisms such as coral, shells, and microorganisms. Over millions of years, these organic materials accumulate and undergo compaction and cementation to form limestone deposits.

Microcrystalline limestone is an example of an inorganically precipitated sedimentary rock. This rock formed when water was saturated with calcium carbonate that precipitated as tiny crystals of calcite. Organic sedimentary rocks form from the action of organisms. Examples include fossiliferous limestone and coal.
