Samples of ten successive volcanic flows were collected from the Marysvale area, Utah. A traverse was made on Agate Peak. The samples were analyzed by standard petrographic techniques to determine mineralogic changes. Results of this study indicate that successive flows at increasing depths originated from an earlier-differentiated magma chamber.
