| 摘 要： | 通过光学显微镜、SEMI、CP-MS等方法对水银洞金矿床黄铁矿的形貌学、地球化学等标型进行研究,发现黄铁矿具有草莓状、粗粒、细粒、生物碎屑状、胶状等5种类型,且热液型的细粒、生物碎屑状、胶状黄铁矿具有较好的含金性;黄铁矿成矿时矿物成分具有不均匀性,成矿环境动荡变化,导致热液型黄铁矿发育有多层性质各异的环带,进一步证实了黄铁矿具有"三层式"特征;各类型黄铁矿的微量元素具有一定差异。在结合前人研究工作的基础上,通过对黄铁矿的Co/Ni,S/Se和Au/Ag等成分标型数据进行分析,认为成矿热液与深源流体有关。

| Abstract: | Researches of optical microscopy,SEM ICP-MS on morphology,geochemistry and other typomorphic characteristics of various pyrites show 5 types of pyrite in Shuiyindong gold deposit,i.e.strawberry pyrite,coarse grain pyrite,fine grain pyrite,bio-detrital pyrite and colloidal pyrite.The fine garained hydrothermal,bio-detrital and colloidal types are better in their auriferous property.In the ore-forming process ore materials were varied and environment unrest leading to multi-rings of the hydrothermal pyrite,i.... |
