Is it true that Dolomite rock forms through the replacement of limestone by magnesium-rich groundwater?

Yes. Multiple geological and petrological sources confirm that dolomite rock commonly forms through the diagenetic replacement of limestone (calcite) by magnesium-rich groundwater, brines, or hydrothermal fluids.
