The origin of sedimentary dolomite has become a long-standing problem in the Earth Sciences. Some carbonate minerals like ankerite have the same crystal structure as dolomite, hence their genesis may provide clues to help solving the dolomite problem. The purpose of this study was to probe whether m...
