University of Minnesota''s Mineral Pages: Dolomite

Dolomite forms in hydrothermal veins or as a porefilling mineral in carbonate rocks, and more rarely as an accessory component in igneous pegmatites or altered mafic igneous rocks. By far though, most dolomite occurs in altered sedimentary marine rocks called dolostones or in marbles formed from the metamorphism of dolostone.
