摘要
峨眉山玄武岩是当前研究的热点 ,本文从以下方面论述了峨眉山玄武岩研究中存在的一些问题 :时空分布 ;岩石组合 ;高Ti和低Ti玄武岩 ;与其它典型大陆溢流玄武岩的异同点 ;与地幔柱的关系和地幔柱的起因。对这些问题提出了一些新的认识和解释 ,或者提出了解决这些问题的途径。这些问题的解决 ,对研究峨眉山玄武岩本身以及地幔柱
Emeishan basalts have become a popularly investigated field recently. This paper deals with some problems concerning the study of this topic: temporal_spatial distribution; rock associations; high_Ti and low_Ti basalts; similarity and difference between these basalts and other CFB, and their relation to mantle plume and the genesis of the plume. The new recognition and explanation of these problems are proposed, and the methods for solving them are also suggested. Answering these problems will play an important role not only in the study of the Emeishan basalts and the mantle_plume interaction, but also in the investigation of their relation to mineralization.
