Dolomitization
Dolomites are carbonate rocks mainly composed of the mineral dolomite. The mineral is stable in seawater in nature and not known examples of its direct extraction from seawater in large quantities required for origin of dolomite rocks. Dolomite occurs by suppression of aragonite or calcite, i.e. dolomitization process.

Dolomite Countertop
Dolomite is a natural stone that forms on the earth's surface. Quartz is an engineered stone. It's about 90% quartz material bound in a mixture of pigments and resin. Quartz countertops are non-porous, meaning they won't stain, and you don't have to seal them. On the other hand, dolomite is a porous stone you'll need to seal annually.

The dolomite process began later and it left out the Latemar and the Marmolada, possibly because they were covered by volcanic rocks.

dolomitization, process by which limestone is altered into dolomite; when limestone comes into contact with magnesium-rich water, the mineral dolomite, calcium and magnesium carbonate, CaMg (CO 3) 2, replaces the calcite (calcium carbonate, CaCO 3) in the rock, volume for volume. Dolomitization involves recrystallization on a large scale.

A fluctuating solution to the dolomite problem | Science
Dolomite growth, layer by layer. A maturation process is favored by fluctuations in the fluid chemistry, allowing episodic dissolution of the disordered regions and growth of the ordered ones. A precipitate of disordered calcium-magnesium carbonate (a proto-dolomite) will reorganize into ordered dolomite by ripening.
