沉积物物源组成的定量估计方法

Method of Parting End-members and Its Consistency from Oceanic Sediments

混合源沉积物中,各种物源物质的成分及其百分含量是地质研究的重要基础信息。本文提出用成分数据统计分析算法,分析处理沉积物样品的地球化学数据,定量提取沉积物中各物源端元的平均化学成分及其百分含量;将该方法用于已知端元成分和端元含量的实验样品数据,计算结果与实际非常吻合;将该方法用于某海区实测沉积物地球化学数据,成功地分离出了陆源、火山源、生物源物质成分和含量。该方法也适合于岩石学、环境污染研究等领域。

First,composition data analytic method used on parting origin end-member from oceanic sediments is introduced,and then the method is demonstrated with experiment data.The end-member consistency obtained from experiment data is very close to that from the real case,which proves that the method is efficient on parting end-member from oceanic sedimentary samples.The method is also adaptable on petrology,pedology and water pollution study.
