Dolomite and calcite look similar under a microscope, but thin sections can be etched and stained in order to identify the minerals. Photomicrograph of a thin section in cross and plane polarised light: the brighter mineral grains in the picture are dolomite, and the darker grains are calcite.
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 ...
The Dolomites (Italian: Dolomiti [doloˈmiːti]), [1] also known as the Dolomite Mountains, Dolomite Alps or Dolomitic Alps, are a mountain range in northeastern Italy. They form part of the Southern Limestone Alps and extend from the River Adige in the west to the Piave Valley ( Pieve di Cadore ) in the east.
The Sugar Run Dolomite is a geologic formation in Illinois. It is a finely-bedded dolomite, preserving fossils dating back to the Silurian period. This formation is named for the Sugar Run stream in Joliet, along which it is well exposed. The dolomite is off-white/grey on freshly cut surfaces but over time oxidizes to a distinctive cream yellow ...
Lannon stone is a type of buff-colored, blocky, sedimentary Dolomite (rock), whose name is derived from Mr. William Lannon, one of the original settlers of the Village of Lannon, Wisconsin. Lannon stone can be found throughout the Niagara Escarpment, which runs underneath much of the Great Lakes. Lannon stone is known for its durability and is ...
Sedimentary petrologists have debated why dolomite is so prevalent in Missouri relative to limestone, even though marine conditions often favor limestone formation. Only a few dolomite beds formed after the Middle Ordovician and few are younger than the Joachim Dolomite. Fault fractures suggest that groundwater altered limestone to dolomite ...
