| 摘 要： | 湘黔地区内生金矿的形成和时空分布,受中晚元古代以来发育于川中古陆东南活动边缘古板块俯冲带制约。这种制约表现为俯冲、碰撞,并多次向洋迁移和与之伴随的构造—岩浆活动。从而在容矿地层层位、成矿时间跨度、矿床类型、矿物组合、元素组合、金的赋存形式、金的成色以及与岩浆岩的关系等方面,从西北向东南呈现规律性变化。

| Abstract: | The formation and distribution of gold mineral deposits in Hunan and Guizhou are restrained by the old plate subduction zone developing on the active continental margin in the middle of Sichuan Oldland of mid-lat Proterozoic. The Restraint is embodied in plate subdtction, collision and the repeated movements towards the ocean and the accompanied structural-magmatic activities. The ore-bearing layey location, metallogenetic time-span, gold deposit type, mineral combination, element combination, existing form, relative purity of gold and the relationship between gold deposit and magmatic rock all change regularily from northwest to suntheast. |
