Brucite is present as granules, blades and needles disseminated in magnesian limestone at Wilkinson, Ontario. It is similar in character and occurrence to brucite described from limestones in other localities. In several of these occurrences brucite has been considered to have been formed by hydration of periclase resulting from decomposition of dolomite. The brucite from Wilkinson contains no remnants of periclase and is considered to be the result of a single process in which H 2 O, probably in the vapor phase, replaced CO 2 of dolomite.
