| 摘 要： | 现代洋底多金属块状硫化物和陆上贱金属块状硫化物矿床中的含金性调查研究证实：海底沉积喷流作用不仅能形成十分重要的贱金属硫化物矿床，而且也能导致金的明显富集。通常形成于弧后或岛弧环境下的同长英质火山岩有关的块状硫化物中的金含量较高。大量的金矿床地球化学研究工作已识别出一些沉积喷流型金矿床，此外还发现即使是具有明显后生成矿特征的太古宙绿岩带中的脉状金矿床也显示出其同沉积喷流作用密切的时空关系

| Abstract: | The investigation on the content of gold in recent submarine poly metallic massive sulfides and land-based massive base sulfide deposits demonstra te that the submarine sedimentary-exhalation not only causes accumulations of p olymetallic massive sulfides, but also results in obviously enrichment of gold. The massive sulfides related to felsic volcanic rocks in the back-arc and island arc environments have higher content of gold. According to a vast amount of geo chemical research works on gold deposits , some sedimentary-exhalation type gold deposits have been distinguished. In addition, the close spatial and tempora l relation of sedimentary-exhalation to the Archaean lode gold deposits that hav e distinct characteristics of epigenetic mineralization also has been discovered . |
