摘　　要：太平洋板块边界和内部均发育大量火山,是研究地球火山的天然实验场。综述了太平洋火山特征与深部成因机制,表明研究人员对地球不同环境下的火山(包括大洋中脊、俯冲带岛弧、板内地幔柱等)进行了系统性研究,分别构建了减压熔融、俯冲板片脱水与富水地幔楔熔融、地幔柱高温熔融的经典模式。但目前学界对于板内非地幔柱型火山的深部岩浆起源以及浅部喷发通道等重要科学问题仍缺乏清晰的认识。未来需要采用创新观测手段,开展多学科交叉研究以取得突破。A large number of volcanoes with distinct origions are developed on the tectonic boundaries and interior of the Pacific plate,thus the Pacific Ocean is an excellent laboratory to study volcanism on Earth.This review finds out that,scientists have conducted systematic researches of volcanism at mid-ocean ridges,subduction zone island arcs,and intraplate mantle plumes,proposing classical models of decompression melting,slab dehydration-induced mantle melting,and plume-related high temperature mantle melting.However,the deep origins and shallow channels of non-plume intra-plate volcanoes are still poorly understood.To address these important scientific issues,comprehensive multi-disciplinary joint observations must be conducted in the future.
