摘要：

The purpose of this letter is to document the occurrence of anhydrite within a pumice phenocryst, and to determine the sulfur contents of the quenched melts in this pumice and to consider if the anhydrite could have crystallized from the magma. Additionally, the presence is noted in the Central Cordillera, potentially below Nevado del Ruiz, of sulfide- and sulfate-bearing deposits of possible relevance to this problem. © 1990.
