Dolomite is both a mineral and a rock. The mineral is a pure form sedimentary rock-forming mineral that can be found all over the world and is quite common in sedimentary rock formations. The rocks formed are a sedimentary carbonate structure composed mostly of Dolomite but also with impurities such as Calcite, Quartz, and Feldspar.Carbonate rocks: limestones and dolomites. Limestones and dolostones (dolomites) make up the bulk of the nonterrigenous sedimentary rocks. Limestones are for the most part primary carbonate rocks.
