Controls of Melt Genesis and Evolution at Buldir Volcano in the Western Aleutian Island Arc
<p>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) …

Compressible Convection and Subduction: Kinematic and Dynamic Modeling
… of high-Mg# andesites in the western Aleutians. The results show that the localization of high-Mg# andesites is a consequence of the time-dependent convergence rate and slab age along the Aleutian arc. The influence of mantle and slab parameters as well as compressibility on the slab …
