Dolomite (also known as dolomite rock, dolostone or dolomitic rock) is a sedimentary carbonate rock that contains a high percentage of the mineral dolomite, CaMg(CO 3) 2. It occurs widely, often in association with limestone and evaporites , though it is less abundant than limestone and rare in Cenozoic rock beds (beds less than about 66 ...
Dolomite (/ ˈ d ɒ l. ə ˌ m aɪ t, ˈ d oʊ. l ə-/) 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 (see Dolomite (rock)). An alternative name sometimes used for the dolomitic rock type is dolostone.
Marble is a rock resulting from metamorphism of sedimentary carbonate rocks, most commonly limestone or dolomite. Metamorphism causes variable re-crystallization of the original carbonate mineral grains. The resulting marble rock is typically composed of an interlocking mosaic of carbonate crystals.
Carbonate rocks are a class of sedimentary rocks composed primarily of carbonate minerals. The two major types are limestone , which is composed of calcite or aragonite (different crystal forms of CaCO 3 ), and dolomite rock (also known as dolostone), which is composed of dolomite (CaMg(CO 3 ) 2 ).
It is a cream-coloured limestone with a pervasive mottling of darker dolomite. The mottling gives the rock a tapestry-like effect, and it is popular for use as a building and ornamental stone. [1] [2] [3] Tyndall Stone is highly fossiliferous and the fossils contribute to its aesthetic appeal.
Dolomite may refer to: Dolomite (mineral), a carbonate mineral; Dolomite (rock), also known as dolostone, a sedimentary carbonate rock; Dolomite, Alabama, United States, an unincorporated community; Dolomite, California, United States, an unincorporated community; Dolomites, a section of the Alps; Lucanian Dolomites, a mountain range in ...
The term is most commonly used in Alaska and the Yukon Territory. [29] Crushed stone rock crushed and graded by screens and then mixed to a blend of stones and fines. It is widely used as a surfacing for roads and driveways, sometimes with tar applied over it. Crushed stone may be made from granite, limestone, dolomite, and other rocks.
[4] [3] The remaining carbonate rock is mostly dolomite, a closely related rock, which contains a high percentage of the mineral dolomite, CaMg(CO 3) 2. Magnesian limestone is an obsolete and poorly-defined term used variously for dolomite, for limestone containing significant dolomite ( dolomitic limestone ), or for any other limestone ...
