Abstract
Hydrothermal experiments with fresh basalt in a high pS2 environment yielded cordierite–sulfide-bearing assemblages. These results suggest that during thermal metamorphism of a volcanic exhalative sulfide deposit, progressive sulfurization of the enclosing basalts takes place. Cordierite–anthophyllite and cordierite–andalusite assemblages will result if Fe combines with S to form sulfides and Ca is removed, possibly as CaSO4.Keywords
