摘    要:物源分析是盆地和造山带研究的一项重要内容,它对分析沉积盆地与造山带的相对位置、演化过程及相互作用等方面意义重大。物源分析方法众多,中主要讨论了重矿物法、碎屑岩类法、裂变径迹法、沉积方法、地球化学和同位素法等的方法、原理及其应用条件和局限性,并指出地球化学方法和同位素方法具有广阔的应用前景。同时,也应该考虑构造抬升、剥蚀作用和化学风化等构造和沉积作用对物源区判定的影响。物源分析时应注意将多种方法相结合,扬长补短,才能得出合理的结论。

关 键 词:物源分析  重矿物  裂变径迹  碎屑岩  沉积  地球化学  同位素

Abstract:Provenance analysis is the most important aspect in the research of ba sins and orogene and is of great significance in studying the relative position, evolution and the interaction of the basins and orogenes. There have been various ways in provenance analysis. The paper has discussed the ways, rules an d limitations of heavy minerals, clastic rock components, fission track, sedimen tary, geochemistry and isotopic methods. It is showen that geochemistry and iso topic methods have the bright and wide uses in the future. Meanwhile, the influence structure and sedimentation such as structure uplift, erosion, chemical weathering on provenan ce can not be neglected. It is worthy to note that reasonable conclusion sho uld be drawn only through the combination of various ways of provenance analysis .
Keywords:provenance analysis    heavy minerals    fission track    sedimentary    ge ochemistry    isotope
