在对沉积盆地分析和古地理分析中,物源分析起着极为关键的作用,可提供盆地与物源区相对位置变迁、构造演化过程、相互作用方面及沉积环境的证据。物源分析的研究方法众多,其中岩石学的研究方法是最基础,也最直观。这种方法包括对沉积盆地内岩石碎屑和重矿物的分析以及对造山带的分析,应用时须注意研究区的地质条件选择合适的方法进行综合研究,才能得出符合其区域构造背景的合理的结论。
In the analysis of sedimentary basins and palaeogeography, provenance analysis plays a crucial role in providing evidence of the relative location of basin and provenance, tectonic evolution, interaction and sedimentary environment. There are many research methods for the analysis of provenance, of which the research methods of petrology are the most basic and the most intuitive. This method includes the analysis of rock debris and heavy minerals in sedimentary basins and the analysis of orogenic belts. When applying, it is necessary to pay attention to the geological conditions of the study area and choose the appropriate method to conduct a comprehensive study so as to obtain the reasonable reasonableness of the regional tectonic setting Conclusion.
