本文引用地质矿产部“七五”东北太平洋CCB53孔柱状沉积物（＜63μm）的元素地球化学分析数据，采用“标准元素对比值法”定量分离Mn元素在不同物源（陆源、生物源、热液源和自生源）中的绝对含量，确定Mn元素地球化学本底，提取CCB53柱状沉积物中Mn元素的正、负异常。据此讨论了Mn元素发生活化、迁移和再沉淀的时间演化规律，即从沉积物的底部到顶部（22．42～0Ma），Mn元素经历了四个活化、迁移和沉淀旋回，分别为840～320、320～170、170～120和120～0。Mn元素的正、负异常分布与自生源组分和氧化还原环境的变化对比分析表明，Mn元素正、负异常分布与自生源组分的高→低变化规律和氧化还原条件的周期振荡紧密相关。早期成岩过程中发生的氧化还原环境的振荡是元素发生活化、迁移和沉淀的动因。
In this paper, the elemental geochemical data of CCB53 columnar sediments (<63μm) in the northeastern Pacific from the “Seventh Five-Year Plan” of the Ministry of Geology and Mineral Resources are used to quantitatively separate Mn elements from different provenances (terrigenous, biogenic and hot Liquid source and authigenic source), determine the geochemical background of Mn element, and extract the positive and negative anomalies of Mn in CCB53 columnar sediments. Based on this, the time evolution of Mn element activation, migration and reprecipitation was discussed. From the bottom to the top of the sediment (22.42 ~ 0Ma), the Mn element underwent four activation, migration and precipitation cycles, respectively 840 ~ 320, 320 ~ 170, 170 ~ 120 and 120 ~ 0. Comparative analysis of the positive and negative anomalous distributions of Mn and the changes of the authigenic components and the redox environment shows that the positive and negative anomalies of Mn are closely related to the high → low variation of the self-generating components and the periodic oscillations of redox conditions . Oscillation of the redox environment that occurs during early diagenesis is the motivation for the activation, migration and precipitation of elements.
