摘要
沉积物物源分析是研究盆地与造山带关系的重要途径。沉积物的地球化学特征在物源分析中起了非常重要的作用。通过查阅近几年相关文献资料,总结出常量元素与微量元素特征在沉积物物源分析中的主要应用:判断物源区的构造背景与判别沉积物源区物质组成等。地球化学是直观、简捷、实用、有效的分析方法之一。但沉积岩易受其它地质因素影响,在实际研究中,还需结合研究区的地质背景以及综合运用多种方法进行物源区分析。
Provenance analysis of sediments is an important way to study the relationship between basin and orogenic belt. The geochemical characteristics play an important role in provenance analysis. In this paper, through consulting the related literatures in recent years, application of major element characteristics and trace element characteristics in the provenance analysis was introduced, for example discriminating the tectoic setting and composition of the provenance. The geochemistry is one of the straightforward, simple and effective analysis methods. But the sedimentary rock is easily affected by the other geological factors, in the actual research, we must combine with the geological background of regional geology to analyze the provenance by various methods.
