Controls of Melt Genesis and Evolution at Buldir Volcano in the Western Aleutian Island Arc
The geochemistry of western Aleutian seafloor volcanoes indicates that primitive dacitic lavas (63-71% SiO2, Mg/Mg+Fe > 0.65) containing low abundances of middle and heavy rare-earth elements (Yb) were probably produced by melting of an isotopically MORB-like (e.g., 87Sr/86Sr < 0.7027) pyroxen...
