摘　　要：对拉木巴洛盆地进行物源区分析对于确定盆地的性质、划分类型和推断其所处的区域构造演化过程是非常重要的。本文运用岩石学、岩相古地理学和沉积构造学的理论 ,采用矿物分析、粒度分析、砾石成分及古流向分析和碎屑骨架分析的方法 ,并结合区域地质概况和区域构造演化特征 ,循序渐进的追索出拉木 -巴洛盆地内沉积物的来源 。It is very important to analyze the resources of sediment in the Lamu Baluo basin for determining its nature,dividing its type,deducing its evolution of regional tectonic On the base of the theory on petrology,paleo geography,grain analysis paleo river's running direction and the analysis of sedimentology, gravel's composition and scraps' framework Combing the general situation of regional geology and the character of tectonic evolution, this paper traces systematically the resources of sediment in the Lamu Baluo basin, and models afresh its pattern
