摘　　要：近30年来,对地幔柱的研究和探索取得了重要进展,对地幔柱在成矿学方面的应用也有了较深入的研究。湘南地区存在有地幔柱二、三次演化阶段的地质记录,即以宁远-道县为中心的二次柱和以骑田岭为中心的三次柱,通过对它们的认识和研究,有助于在找矿思路方面获取一些新的启示。Since 1970s,a great progress about studying and researching on mantle plume has been obtained,as well as a deeper investigation about the application of mantle plume to metallogeny has also been acquired.There are geological records for the second and third time evolving stages of mantle plume in southern Hunan,that are secondary mantle plume centered by Ningyuan-Dao County,and third-time mantle plume centered by Qitianling.Knowing and studying the two stages mantle plume will be helpful to find out some ne...
