| 中文摘要: |
| 黑色岩系是含硫化物和有机质较高的暗色泥质岩、硅岩、碳酸盐岩组合,黑色岩系中以海底热液喷流作用形成的矿床是国际研究热点。因为海陆变化、壳幔作用以及全球构造变动均导致黑色岩系和SEDEX矿床的演化,所以研究湘黔张家界—遵义地区有机物从保存、埋藏、生烃、排气到过成熟,均与微生物的生命代谢、内生地质作用、成矿机制同步谐动,地球化学影响和生物成矿作用与全球性的气候变迁、缺氧事件相关联,而且以上研究集中体现在事件地质学的成因解释、热水喷流沉积作用、生物矿化与金属矿化、矿物成因与环境影响、铂族元素矿物、黑色页岩石煤与金属矿化、元素地球化学影响等方面。研究数据充分显示了特定的地质背景、成矿环境、生物作用机制在黑色岩系SEDEX矿床成岩成矿中的作用。 |
| 英文摘要: |
| The black rock series is the dark-colored argillaceous,siliceous,carbonate rock assemblage which is rich in sulfide and organic matter.And the Sedex mineral deposits in the assemblage are the focuses of the international research.The sea-continent change,crust-mantle interaction and the global structural variation all lead to evolution of the black rock series and Sedex mineral deposit.Preservation,burial,hydrocarbon generation,gas discharge and over maturation of organic matter in the research area are all in coherent harmony with the bacteria metabolism,the regional innate geologic role.The geochemical influence and bio-metallogenic role are connected with the global climate migration and anoxic event.The researches are mainly concentrated on genetic explanation of the geological event,Sedex activity,bio-metallogenic role and metal mineralization,genesis of minerals and environment influence,PGE minerals,black shale,bone coal and metal mineralization,elemental geochemical influence.Data obtained reveal evidently the role of the specific geological background,metallogenic environment,bio-metallogenic mechanism in rock-forming and ore-forming processes of Sedex mineral deposits in the black rock series. |
