| 中文摘要: |
| 文章对浙东南火山岩地区燕山期金银铅锌矿床的控矿因素和成因进行了分析研究,认为浙东南燕山期金银铅锌矿属于浅成中低温热液矿床,其热液来源于雨水,成矿物质来源于围岩,水源和热源在成矿过程中起着决定性的作用,陆缘火山活动的地质背景决定了水在成矿作用中的特殊作用,决定了矿床的空间分布,含水的断裂构造和沉积建造是寻找大型矿床的最有利地段。 |
| 英文摘要: |
| Based on the study of ore-controlling factors and metallogenesis, it was concluded in this paper that the Au,Ag,Pb,Zn deposits related to Yanshan volcanic rock in Southeastern Zhejiang were meso-epithemal deposits, and the hydrothermal fluid was originated from rainwater, and ore-forming materials were derived from wall rock as well. So water source and heat source were the key factors in the ore-forming process. Water played a special effect on the ore-forming process and deposits distributed because of continental margin of volcanic activities. It was concluded that water-bearing faulted structure and sedimentary formation were the optimistical section for large-scale deposit. |
