摘要
1.Introduction The oceanic arc basalts and continental arc andesites are typical products of subduction zone magmatism(Straub et al.,2011;Zheng et al.,2020).However,there has been controversy over the lithology of their magma sources.As this issue is closely related to both physicochemical and geodynamic mechanisms of subduction zone magmatism,it has become one of the key issues in the study of convergent plate margins(Zheng et al.,2022).
