However, chlorine does not partition readily into calcite, aragonite, or dolomite (natural and synthetic samples generally contain < wt% Cl; Kitano et al., 1975; Staudt et al., 1993), casting doubt on the viability of this method unless abnormally high Cl concentrations or inclusions of minerals such as halite are observed in Martian magnesium carbonates.

Halophilic Archaea Mediate the Formation of ProtoDolomite ...


 · In the past several decades, sulfate concentration and salinity have been considered to be the two essential hydrochemical factors in the formation of dolomite, yet arguments against this hypothesis have existed simultaneously. To clarify the effects of sulfate concentration and salinity in the mineralization of dolomite, we conducted experiments on dolomite precipitation mediated by a ...

The Dolomite Problem | Discover Magazine


 · The Dolomite Mountains, Italy's Alpi Dolomitiche, however, are a special case: the rock in them was originally simple calcium carbonate made from dead corals and seashells on the seafloor. Only later was it transformed into dolomite through the orderly addition of magnesiumand through the action, McKenzie suspects, of sulfatereducing bacteria.
