If nesquehonite or hydromagnesite saturation is reached, the model will precipitate the predicted Mg carbonate.
Brucite may be destabilized in surface environments (regolith or outcrop) and converted to hydromagnesite and atinite (Schilling 1968).
Depending on the degree of weathering and ore grade, brucite can be altered to hydromagnesite or atinite for depths down to, or greater than, five metres.
Hydromagnesite is a common constituent of the serpentinite surrounding the mercury-mineralized silica-carbonate rock.
