摘要
利用重矿物的相关性分析、因子分析、Q型聚类分析、稳定系数分析、平面组合特征分析以及古地貌地形分析等,对吐哈盆地鄯善弧形带三间房组二段的重矿物组分进行了统计研究,认为该区母岩类型主要为沉积岩和变质岩,分别对应南部塔克泉凸起主要物源区和东南部了墩隆起次要物源区,其中塔克泉凸起物源区主要控制弧形带丘陵地区辫状河三角洲扇体展布形态,了墩隆起物源区主要控制温吉桑地区辫状河三角洲扇体展布形态,丘陵东部地区则为两大物源交汇区。
Based on the analyses of correlation, factor, Q type cluster, stability coefficient, plane assemblage features and paleogeomorphology, this paper studied the heavy mineral components of the second member of Sanjianfang Formation in Shanshan arcuate belt. The result shows that the source rock types are mainly sedimentary rock and metamorphic rock, which respectively responds to the primary provenance in Takequan uplift in the north and the secondary provenance in Liaodun uplift in the southeast. The provenance in Takequan uplift controls the sedimentation of braided delta fan in hill country, and the provenance in Liaodun uplift controls the sedimentation of braided delta fan in Wenjisang area. The eastern hill country is the intersection of Takequan uplift provenance and Liaodun uplift provenance.
