Dolomite: occurrence, evolution and economically
The fact that much smaller pore volumes of hypersaline water are required to dolomitize a given volume of limestone, and the allied observation that most modern dolomite is associated with evaporitic settings, has led Friedman (1980) to state "dolomite is an evaporite mineral," while Sun (1994) suggests that most large-scale dolomite has ...
