The limestone comprises calcite or double carbonate consisting of calcium and magnesium (dolomite).Limestone Limestone is one of the most widespread sedimentary rocks. Many organisms, from corals to microscopic foraminifera, grow shells composed of carbonates. Most limestone forms when these organisms die and their carbonate shells accumulate in shallow seas. Common sedimentary rocks include sandstone, limestone, and shale. These rocks often start as sediments carried in rivers and deposited in lakes and oceans. When buried, the sediments lose water and become cemented to form rock. Tuffaceous sandstones contain volcanic ash.
