研究了沉积和成岩过程中稀土等微量元素的化学状态及其化学行为,通过地球化学示踪剂检测沉积物中反映沉积环境的微量元素。在海洋沉积物中,沉积过程中与锰氧化物结合的稀土元素在成岩作用过程中由锰氧化物溶解释放出来,而释放出来的稀土元素在成岩作用过程中被磷灰石等磷酸盐相吸收。通过沉积和成岩作用,证实了沉积岩中的稀土元素模式整体上继承了其特征,是反映沉积环境的一种有用的地球化学工具。
英文摘要
Chemical state of trace elements such as rare earth elements (REE) and their chemical behavior during sedimentation and diagenesis were studied, in order to examine trace elements in sediments on the geochemical tracer reflecting their sedimentation environments. It is shown on marine sediments that REE incorporated into Mn oxides during sedimentation were released from Mn oxide dissolution during diagenesis, but the released REE were absorbed to phosphate phase such as apatite during the diagenesis. REE patterns in sedimentary rocks are confirmed to inherit their features as a whole through sedimentation and diagenesis and to be an useful geochemical tool reflecting the depositional environment.
