| 中文摘要: |
| 代隆金矿床产于燕山期花岗斑岩体的蚀变矿化破碎带中,围岩为上三叠统新都桥组板岩夹变质砂岩,金矿体赋存在破碎蚀变的花岗斑岩中,金矿化与硅化、黄铁矿化、毒砂化和褐铁矿化关系密切。文章论述了金矿床所处的区域地质背景、矿区和矿床地质特征以及地球化学特征,初步分析了矿床的成矿条件和控制因素。此外提出了一些尚需进一步研究的问题,希望能引起关注与探讨。 |
| 英文摘要: |
| The Dailong gold deposit is located in the altered and mineralized fracture zone within the Yanshanian granitic pluton. The wall rock is the slate with the intercalation of meta-sandstone of the Xinduqiao formation of Upper Triassic, the gold ore bodies are hosted in the fractured and altered granitic pluton. Main wall rock alterations such as silicification, pyritization, ferritization and arsenopyrite, are closely associated with gold mineralization. The paper introduces the regional geological background, geological features and geochemical characteristics, and analyzes the ore-forming conditions and ore-controlling factors. Finally the authors propose some key issues to be paid attention in the future exploration work. |
