Dolomite (/ ˈ d ɒ l ə m aɪ 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 dolomitic rock .
Dolomite or dolostone is a carbonate sedimentary rock containing more than 50% by weight of the mineral rock may contain calcite, but the content of calcite should not exceed 10% of the calcitedolomite pair''s content 3.. Dolomite in Northern Norway (Trollholmsund) which was once chalk, but the original material has been replaced with dolomite.
The term limestone encompasses several forms of sedimentary rock composed primarily of calcium carbonate. Limestone may form from chemical processes instigated by large populations of algae, or may form as the shells from aquatic creatures and singlecelled organisms form a .
Granite is a very hard stone and resistant to damage. Though the composition of various granite colors and varieties will vary from slab to slab, granite is generally is made up of a quartz, feldspar and an assorted variety of minerals, evoking a gritty look. However, granite is still vulnerable to staining.
Granite is a very hard, granular, crystalline igneous rock which consists mainly of quartz, mica, and feldspar and is often used as building stone. Dolomite is a sedimentary rock containing more than 50 percent of the mineral dolomite by weight. .

Sep 27, 2004· 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) old USGS publications, it was referred to as magnesian limestone, a term now reserved for magnesiumdeficient dolomites or magnesiumrich has a stoichiometric .
Y. Daoxian, in Treatise on Geomorphology, 2013. Lithology. Carbonate rocks are composed of a full Ca/Mg chemical gradient from limestone to dolomite. Old phase limestone is more compact and hard with a porosity usually less than 1% and higher mechanic strength, whereas dolomite generally has a porosity of about 5% and lower mechanical strength.
