Basalt derived from highly refractory mantle sources during early Izu-Bonin-Mariana arc development
Abstract
Magmatism associated with early growth of subduction zones is unlike that of mature island arc systems. Here, the authors find basalts with distinct mineralogical and geochemical characteristics were erupted during this early stage, and derived from extremely refractory, hot mantle sources.
