沉积物物源分析是盆地分析的重要内容,是再现沉积盆地演化、恢复古环境的重要依据。简要回顾了物源分析的发展史,重点介绍了重矿物、沉积物地球化学和同位素测年技术在物源分析中的应用和发展,指出了物源分析中尚需解决的地质问题。在强调多种方法综合使用的同时,也应考虑构造背景和化学风化作用。
Provenance analysis is important for sedimentary basin analysis and also the essential evidence for the evolution and ancient environment of a basin. After a general review of the provenance study, the paper introduces, in particular, the application and development of heavy mineral, sediments geochemistry and isotope technology. It suggests that various methods should be combined to explain provenance and that tectonic setting and chemical weathering should not be neglected. It also points out that some geolog- ical questions are not unanswered.
