commonGeological Context
Dolomite is a common rock-forming mineral that primarily forms in sedimentary environments, often through the diagenetic alteration of limestone (dolomitization) or as a primary precipitate in hypersaline conditions. It is the main component of the sedimentary rock dolostone.
