摘　　要：地幔柱及其成矿系统研究是当前地学领域的热点之一,在我国已取得了较大进展,发表了大量论著。但对环太平洋极性超级地幔柱成矿系统的研究,目前还处于起步阶段。文章在前人研究成果的基础上,从以下几方面作了简要论述:1)地幔柱研究历史的回顾;2)地幔柱类型划分与成矿场;3)常规地幔柱判别标志;4)环太平洋极性超级地幔柱的厘定;5)环太平洋极性超级地幔柱成矿效应;6)华南亚地幔柱与成矿;7)环太平洋极性超级地幔柱的动力学讨论。笔者认为,中-新生代濒太平洋洲际性成矿域及其成矿大爆发,导源于太平洋超级地幔柱对成矿的响应。Study on mantle plume and the metallogenic system is a hot topic of current research and has made great progress in China by a large number of publication.The study of metallogenic system by super mantle plume in the Pacific rim is still in its initial stage.On the basis of previous research,this paper briefly discussed this topic in following aspects：（1）briefly reviewing the history of mantle plume study;（2）mantle plume type and its metallogenic field;（3）discrimination criteria of regular plume;（4）the redefinition of Pacific rim super mantle plume;（5）metallogenic effect of the polarized Pacific rim super mantle plume;（6）sub mantle plume of South China and the metallogenesis;（7）dynamics of Pacific rim super mantle plume.The author suggested that metallogenic domain and metallogenic explosion of Pacific rim in Mesozoic and Cenozoic was the response of Pacific super plume action.
