La dolomita es una roca sedimentaria que se forma cuando la piedra caliza se infunde con agua rica en magnesio. El proceso de conversión de carbonato de calcio en carbonato de calcio y magnesio se conoce como dolomitización . En comparación con la piedra caliza, la dolomita es más dura y menos propensa a reaccionar con los ácidos.
Dolomita () es un mineral de carbonato anhidro compuesto de carbonato de calcio y magnesio, idealmente CaMg (CO3)2< /sub>.
