Calcit – Wikipedia

Calcit, Kalzit, Kalkspat oder Doppelspat, ist ein sehr häufig vorkommendes Mineral aus der Mineralklasse der „Carbonate und Nitrate“ mit der chemischen Zusammensetzung Ca[CO 3] und damit chemisch gesehen Calciumcarbonat.. Calcit kristallisiert im trigonalen Kristallsystem und entwickelt verschiedene Kristall- beziehungsweise Aggregatformen ().

Is It Calcite or Dolomite? | Rock & Gem Magazine

The minerals calcite and dolomite are chemically similar and actually form a series ranging from pure calcium carbonate calcite to pure calcium, magnesium, carbonate dolomite. The magnesium atoms that substitute for the calcium are a bit smaller than those of calcium, and this affects the appearance of many dolomite crystals. Dolomite crystals can show this atomic size difference externally as ...
