摘　　要：峨眉山大火成岩省(ELIP)近几年来取得了许多新的进展,但在一些重要的问题上仍存在着争论,笔者列举了ELIP火山喷发的时间、分布范围、高钛和低钛玄武岩、层状岩体与玄武岩以及成矿作用的关系、大火成岩省与生物绝灭的关系以及与地幔柱的关系等方面存在的问题,以及由此引发的相关争论。这些问题的解决对于大火成岩省研究的深入将会起到重要作用。Although researches on the Emeishan large igneous province （ELIP） have been fruitful in recent years, some important problems remain controversial. This paper has dealt with such important problems as the eruption age, distribution, high-Ti and low-Ti basalts, the relationship between the layered intrusions, basalts and mineralization, the connection to mass extinction and mantle plume, and related issues. The solution of these problems is likely to play a key role in further studies of large igneous provinces.
