Dolomita :: Minerales
La dolomita, denominada de esa forma en honor al geólogo francés Déodat Gratet de Dolomieu, es un mineral compuesto de carbonato de calcio y magnesio [CaMg(CO3)2].Se produce una sustitución por intercambio iónico del calcio por magnesio en la roca caliza (CaCO3). Definida por el mar. Probablemente el mineral dolomita fue descrito por primera vez por Carl Linnaeus en 1768.

Historia. Probablemente el mineral dolomita fue descrito por primera vez por Carl Linnaeus en 1768. [1] En 1791 fue descrito como una roca por el naturalista y geólogo francés Déodat Gratet de Dolomieu (1750–1801), primero en edificios de la antigua ciudad de Roma, y más tarde como muestras recogidas en las montañas ahora conocidas como los Alpes Dolomitas del Norte de Italia.
