| 中文摘要:石英脉型钨矿床是中国数量最多的钨矿床类型，但保有储量消耗迅速，迫切需要创新找矿模型，指导找矿突破。文章结合二十余年的找矿实践，通过详细分析扇状成矿矿床实例，构建了石英脉型钨矿床新的找矿模型。该模型强调赋矿裂隙为岩浆动力成因，在花岗岩体顶部呈扇状分布型式，岩浆期后热液恰在裂隙张开时充填其中而形成扇状成矿系统；提出“就岩找矿”、“就矿找矿”、“就矿找岩”的地质、地球化学和地球物理标志，指导矿床尺度的勘查工程部署。截至目前，该模型已在广东禾尚田钨锡矿床、广西珊瑚钨锡矿床、广西社垌钨钼矿床、江西盘古山钨铋矿床等获得了验证，找矿成效显著。 |

| Abstract:Quartz vein-type tungsten deposits are the most abundant types of tungsten deposits in China, yet the reserves are being rapidly depleted. There is an urgent need to innovate the exploration model to guide breakthroughs in finding new deposits. The article, which combines over two decades of exploration practice, constructs a new exploration model for quartz vein-type tungsten deposits through a detailed analysis of fan-shaped mineralization instances. This model emphasizes that the ore-bearing fractures are of magmatic dynamic origin and are distributed in a fan-shaped pattern at the top of the granite. The fan-shaped mineralization system is believed to have formed when post-magmatic hydrothermal fluids filled the fractures as they were opening. The model also proposes geological, geochemical, and geophysical indicators for "exploration around the granite", "exploration around known deposits", and "exploration around the deposits for granite", guiding the deployment of exploration survey projects at the deposit scale. To date, this model has been validated in the Heshangtian W-Sn deposit in Guangdong Province, Shanhu W-Sn deposit and Shedong W-Mo deposit in Guangxi Province, as well as the Pangushan W-Bi deposit in Jiangxi Province, and has achieved remarkable results in exploration. |
