摘　　要：晚中生代以来太平洋构造域的地质过程明显影响了东亚陆缘的构造演化、岩浆活动和成矿过程,加强对太平洋板块自身演化过程的认识是我们正确理解东亚陆缘构造变迁的基础。文章从太平洋域与特提斯域地质过程对比、古太平洋演化的重要事件和扩张脊俯冲三个方面简要介绍古—今太平洋的构造演化的研究成果,特别是最新成果,分析晚中生代以来太平洋域构造演化对东亚陆缘的可能影响,以期引起学界对开展有关洋陆结合研究的重视,并提供一份快速参考资料。Since the Late Mesozoic,the plate evolution in the Pacific domain has influenced the tectonic evolution,magmatism and mineralization of the East Asia margin.Improving our knowledge about the Pacific evolution will benefit ourunderstanding of the tectonic evolution of East Asia continental margin.In this paper,we summarize updated research resultson the tectonic evolution of the paleo and present Pacific Ocean from three aspects,the distinction between Pacific and Tethystectonic domains,important tectonic events during Pacific evolution and the ridge subduction around the Pacific.Possibleeffects of Pacific domain on the evolution of East Asia continental margin are probed.Our aim is to call on more intensifiedresearch on Asia continent and Pacific Ocean,and to provide an easy reference for such research.
