  • Limestone Wikipedia

    Limestone is 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.

    Jan 30, 2017· Limestone deposits are found throughout the world. They are “mined” in a process known as “quarrying.” This process varies depending on the use of the product. If it is to be made into cement, it is needed in small pieces so that it can be ground

  • What Are the Uses of Limestone? Reference

    Spraying it onto coal surfaces in a mine increases the amount of light and cuts down on coal dust. Limestone's sturdiness makes it hold up through the cycling between freezing and thawing, as well as to other forms of abrasion. Limestone is easier to mine and causes less damage to mining equipment and transport vehicles than harder silicates.

It most commonly forms in clear, warm, shallow marine waters. It is usually an organic sedimentary rock that forms from the accumulation of shell, coral, algal, and fecal debris. It can also be a chemical sedimentary rock formed by the precipitation of calcium carbonate from lake or ocean water. Most limestones form in shallow, calm, warm marine waters. That type of environment is where organis
