    石英的结构和化学组成对矿床成因和找矿勘查的指示及应用

    Texture and chemistry of quartz and its applications in ore genesis and mineral exploration

    • 摘要: 石英作为多种矿床类型中的常见矿物之一,一直是矿床学家和勘查学家重点关注的对象。随着近年来高空间分辨率观测手段和微区分析技术的飞速发展,石英的结构和化学组成研究在揭示矿床成因和指导找矿勘查工作中发挥出越来越重要的作用。鉴于此,文章对近年来不同类型矿床中的石英结构和化学组成特征及其在成矿研究和找矿勘查中的应用进行了综述,重点介绍了热液矿床中石英的结构特征和世代关系的详细厘定,继而结合石英及其包裹体中的元素和同位素体系特征,阐述了石英化学组成对成矿物质来源的示踪、成矿作用过程的反演、成矿物质富集机制的揭示和成矿时代的约束,探讨了石英化学组成及矢量变化在成矿潜力分析、成矿类型判别和矿化位置圈定等方面的指示意义。文章还提出了当前该研究领域存在的主要问题,并对未来的研究方向进行了分析与展望。

       

      Abstract: Quartz is one of the most common minerals in various hydrothermal ore deposits and has long been the focus of economic geologists and prospecting engineers. With the advancement of high-spatial-resolution observation and microanalysis techniques in recent years, the study of quartz textures and chemistry plays increasingly important roles in understanding ore genesis and guiding mineral exploration. This paper provides a review of recent advances in quartz textures and chemistry and its applications for ore genesis and mineral exploration. We first focus on the detailed observation of quartz textures and relevant generations in hydrothermal ore deposits, and then document the applications of quartz trace elements, isotope and fluid inclusion in tracing the source of ore-forming materials, understanding the ore-forming process, revealing the mechanism of ore enrichment, and providing timing constraints on ore formation. Additionally, this paper also explores vector variation of quartz chemistry and its applications in metallogenic potential analysis, ore types discrimination, and delineation of mineralization centers. Finally, we summarized the main issues that may exist in the current study and provided some prospects for future studies.
