carbonate mineral dolomite

  • Dolomite (mineral)

    Dolomite (/ d l m a t /) is an anhydrous carbonate mineral composed of calcium magnesium carbonate, ideally CaMg(CO 3) 2. The term is also used for a sedimentary carbonate rock composed mostly of the mineral dolomite. An alternative name sometimes used for

  • The quot;Acid Testquot; for Carbonate Minerals and Carbonate Rocks

    What is the Acid Test? To most geologists, the term quot;acid testquot; means placing a drop of dilute (5% to 10%) hydrochloric acid on a rock or mineral and watching for bubbles of carbon dioxide gas to be released. The bubbles signal the presence of carbonate minerals such as calcite, dolomite, or one of

    Aragonite and calcite are polymorphs of calcium carbonate. It is harder than calcite (3.5 to 4, which is typical of carbonate minerals. Rock that is primarily dolomite is sometimes called dolostone, but quot;dolomitequot; or quot;dolomite rockquot; are preferred names. In fact, the rock dolomite was named before the mineral that composes it. 05. of 10

    Dolomite forms in hydrothermal veins or as a pore filling mineral in carbonate rocks, and more rarely as an accessory component in igneous pegmatites or altered mafic igneous rocks. By far though, most dolomite occurs in altered sedimentary marine rocks called dolostones or in marbles formed from the metamorphism of dolostone.

  • Introduction List of Most Common Carbonate Minerals

    True dolomite fizzes with acid only when heated; but dolomite is often mixed with calcite, which is active with cold acids. Most limestones contain more or less carbonate of magnesia, so that limestones are sometimes dolomitic, and shade into true dolomite.
