  • 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.

  • Limestone is a very common type of sedimentary rock

    Limestone is a very common type of sedimentary rock. Rocks come in three types: igneous, metamorphic and sedimentary. Sedentary rock forms from deposits of small particles and other debris, usually from the Earth's surface or bodies of water. Limestone

  • Where Is Limestone Found

    Limestone also forms through evaporation in caves where water pours through the floor. The calcium carbonate dissolved and forms deposits throughout the ceiling and wall of the cave. They increase into larger and larger deposits as the years go by and they can reach into the deepest parts of the cave.
