Abstract

Piip Volcano is a hydrothermally active seamount located in the strike-slip regime immediately north of the far Western Aleutian Ridge. Fractionation of hydrous and oxidized magnesian andesites (MA) produced an igneous rock series at Piip Volcano with a lower average FeO*/MgO (more strongly calc-alk...
