1 Introduction. Alteration of ultramafic rocks is ubiquitous in near-surface environments, both on land and below the seafloor. Mantle olivine and pyroxene are unstable at near-surface conditions and undergo hydration (serpentinization) and carbonation when fluids are present (e.g., Moody, 1976).These reactions result in the …

"Brucite, Mg(OH) 2, is a hydroxide typically found associated with serpentine, dolomite, magnesite and chromite as a decomposition product of magnesium silicates, especially serpentine. The brucite spectrum displays the best resolved vibrational bands in the present series, and interpretation of its spectrum has received considerable attention ...

Brucite Group. Name: Named in 1824 by François Sulpice Beudant in honor of Archibald Bruce (February 1777 New York, New York, USA - February 22, 1818, New York, New York, USA), physician, early American mineralogist, and editor of the American Mineralogical Journal, who first described the species. Type Locality:

The Mg isotope fractionation factor between dolomite and aqueous solution obtained from synthesis and exchange experiments converged with time and was independent of dolomite morphology, suggesting attainment of isotopic equilibrium.

Brucite is named in honor of Archibald Bruce (1777-1818), a mineralogist who first described this mineral. As thin tabular plates and groups of such crystals, in foliated …

The Mineral magnesite. The most common form of Magnesite is white, microcrystalline, porous masses that are dull in luster, and have the appearance of unglazed porcelain. Because they are porous, they …
