摘　　要：近年来随着我国海洋矿产资源调查工作的进一步开展,陆续在西南印度洋中脊发现了“龙旂”、“断桥”热液区,但目前国内对于现代海底多金属硫化物矿床控矿因素研究相对比较薄弱。加强该方面的研究,有利于为现代海底新的热液区的寻找指明方向,通过对现代海底已经发现的典型多金属硫化物矿床进行控矿因素的分析,并结合前人研究成果,认为现代海底多金属硫化物矿床的形成,受岩浆作用、断裂构造、海底地形、水深、洋中脊扩张速率、地质盖层、围岩类型、渗透性等多个因素的共同控制,其中,以深部岩浆活动和断裂构造控制最为重要。相关研究结果可以为我国探查海洋矿产资源提供借鉴。In recent years,with the further development of China's marine mineral resources investigation,we discovered the "Dragon" and "Duanqiao" hydrothermal zones in the ridge of Southwest Indian Ocean,but the current domestic research on the ore-controlling factors of modern seabed polymetallic sulphide deposits is relative weak.In order to strengthen research in this area,it is conducive to pointing the way of searching new hydrothermal zones.Through the analysis of ore-controlling factors for typical polymetallic sulfide deposits discovered in the modern seabed,and combined with previous research results,shows that the formation of modern seabed polymetallic sulphide deposits is considered to be affected by magmatic action,fault structure,seabed topography,water depth,mid-ocean ridge expansion rate,geological caprock,surrounding rock type and permeability.Among them,the deep magmatic activity and the fault structure are the two most important factors.The relevant research results can provide reference for exploring marine mineral resources.
