title: Brucite in the Caleareous Alga Goniolithon.
abstract: Brucite, Mg(OH)(2), identified by differential thermal analysis, has been found in the high-magnesian calcite skeleton of Goniolithon, a marine calcareous alga. This mineral amounts to about 5 percent of the skeleton by weight, and can account for the discrepancy between total amount of magnesium determined by chemical analysis and the magnesium in metastable solid solution in calcite as determined by the size of the unit cell of calcite.
