| 摘 要： | 汞是湖南省的优势矿种之一。在当前国内汞矿供应紧张的形势下,研究省内汞矿找矿方向对推动省内汞矿的找矿勘查具有一定的社会意义和经济意义。介绍了湖南省汞矿的基本地质特征及类型,并结合大量的实际地质资料,对湖南省汞矿的成矿控制因素进行了综合分析,结合近年潜力评价提供的汞元素地球化学分布资料,初步提出了湖南省汞矿成矿规律及找矿方向: 湖南省汞矿在时间上主要形成于燕山期,最重要的赋矿地层是寒武系和泥盆系; 在空间上集中分布在湘西汞矿带,其次分布在湘东成汞带,地层、构造、岩浆岩及地球化学异常等共同决定汞矿床的定位。

| Abstract: | Mercury is one of the dominant minerals in Hunan Province. Under the severe situation of current domestic mercury ore supply, the study about mercury ore prospecting direction can help to promote mercury ore prospecting exploration and has certain social and economic significance. Basic geological features and types of mercury mine in Hunan Province were introduced in this paper. Combining with the actual geological data, the ore-controlling factors were comprehensive analysis for mercury mine in Hunan Province. And the Hunan mercury metallogenic regularities and prospecting directions were initially proposed, with potential evaluation in recent years and elemental mercury geochemical distribution data. Many types of mercury deposits in Hunan Province were mainly formed in Yanshan period, and the most important ore-bearing strata are Cambrian and Devonian strata, which are in spatial distribution of Xiangxi mercury ore belt, following by distribution with a mercury in eastern Hunan.The strata, structure, magmatic rocks and geochemical anomaly are combined to decide the positioning of the mercury deposits. |
