Dolomite is very similar to mineral calcite. Calcium is composed of calcium carbonate (CaCO3), while the dolomite is calcium carbonate-copper (CaMg (CO3) 2). It's a crooked mineral.
Named by: Déodat Gratet de Dolomie. Most often they form granular, massive or ball aggregates, pseudomorphoses. Romboedra-shaped crystals have swollen surfaces and usually form chisels.
