A Discussion on Some Problems Concerning the Study of the Emeishan Basalts

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.
