黑色页岩中原生黄铁矿的微量元素含量可以避免被热液作用、重结晶、变质作用等因素干扰,可以作为古海洋环境的指示。本文综合前人数据,利用氧化还原敏感元素(Mo、U、Co、Se等)含量变化指示地质历史时期古海洋生产力条件、氧化还原条件变化趋势。
The trace element content of the primary pyrite in black shale can be avoided as a result of hydrothermal reaction, recrystallization and metamorphism and can be used as an indicator of ancient marine environment. Based on the previous data, this paper uses the changes of redox-sensitive elements (Mo, U, Co, Se, etc.) to indicate the paleoceanic productivity and redox conditions in the geological history.
