The geochemical evolution of the Izu-Bonin arc system: A perspective from tephras recovered by deep-sea drilling
Less than 30 Ma tephra glasses from the Izu-Bonin (IB) arc consist dominantly of low-K tholeiites that are highly depleted in high field strength elements (HFSE), light rare earth elements (LREE), and large ion lithophile elements (LILE). Collectively, these characteristics indicate minimal contributions from the subducted sediment, a dominantly aqueous fluid subduction component transfer mechanism, and highly depleted mantle sources. Subtle temporal variations are evident throughout the...[Show more]
