摘要
沉积岩的主量和微量元素对沉积环境变化有着较高的灵敏度,是研究古沉积环境以及沉积物源区性质的一种有效手段.在大量阅读相关文献的基础上,系统总结了沉积岩不同主微量元素特征在沉积环境和物源分析中的地质应用.特别是对于露头不太发育的地区,地球化学方法是更直观、更实用的分析方法之一,但沉积岩在沉积的过程中很容易受其它地质因素影响.所以,在实际研究中,还需结合研究区的地质背景,科学选样以及综合运用多种方法进行综合分析.
The major and trace elements of sedimentary rocks have higher sensitivity to the change of sedimentary environment,and it is an effective method to study the sedimentary environment and the tectonic setting of sediment source. In this paper,based on a large number of related literatures,the geological application of the characteristics of different main and trace elements in sedimentary rocks in sedimentary environment and provenance analysis is systematically summarized. In particular,the geochemistry method is one of the more intuitive and practical methods of analysis in areas where the outcrop is not well developed. However,the sedimentary rocks are easily influenced by other geological factors during the deposition process. It is necessary to combine the geological background of the study area and scientific sampling to do comprehensive analysis by using a variety of methods in real study.
