关于峨眉山大火成岩省一些问题的研究现状

峨眉山大火成岩省(ELIP)位于扬子板块西缘,是我国唯一被国际学术界认可的大火成岩省,受到国内外学者的广泛关注。主要围绕峨眉山玄武岩喷发前的隆升剥蚀情况、喷发时限、地幔柱的轴部位置等争议性问题进行探讨,总结了前人的研究成果。由于地幔柱和岩石圈之间相互作用的复杂性,加之地幔柱模型的不完善,峨眉山地幔柱活动在地表的真实响应也许更复杂。在今后的研究中,应该加强不同学科间的相互合作,着重研究地球深部动力学过程以及地球系统各圈层的相互作用。

Research Progress on Some Issues on the Emeishan Large Igneous Province

The Emeishan large igneous province (ELIP) is located in the west of Yangtze plate, and is only recognized as a large igneous province by the international community, so many international and domestic scholars pay attention to it. This article mainly discusses some controversial issues: the uplift and denudation before eruption of the Emeishan basalt, the eruption age, axial position of the mantle plume, and summarizes achievements of predecessors. Because of the complexity of interaction between mantle plume and lithosphere, and imperfect of mantle plume model, real surface responses of mantel plume activity may be more complex. In the future research, scholars should strengthen mutual cooperation between different disciplines, and focus on the research about the process of deep dynamic of the Earth and the interaction among various spheres of Earth system.
