%X Aquamarine crystals occur in crustal A-type pegmatite-aplite dykes and associated quartz veins and greisen zones at the Zealand Station Be-Mo deposit, south-central New Brunswick (Canada). Electron-probe microanalysis (EPMA) of aquamarine determined that the chromophore Fe (< 1.4 wt. % FeO<sup>T</sup>) is present in octahedral sites, with substitutions responsible for simple and oscillatory zonation (SEM-BSE imaging). Average water content (1.53 wt. %) was calculated using an empirical formula, consistent with two T<sub>REL</sub> (>800 ¡ãC) of 1.3-1.4 wt. % in beryl channels. The ¦Ä<sup>18</sup>O of the quartz and beryl were within 1  , consistent with magmatic crystallization from an <sup>18</sup>O enriched source, and ¦ÄD values on channel water have magmatic signatures.
