滹沱河是河北平原西部太行山山前冲,洪积扇上具有代表性河流之一.对其上、中、下段~1)已知河流地貌成因类型的沉积亚相(主流相、心滩相、边滩相)的沉积物进行了粒度、矿物及石英表面结构的分析研究. 我们知道,矿物在河流沉积物中的变化,是由多种因素所决定的,但主要是河流的水动力条件和被搬运距离的远近.为此,在说明各亚相间矿物变化时,又在各断面主要亚相中,分别简要介绍了层理构造、粒度和石英表面形态等主要水动力特征,以作为矿
Hutuo River is one of the representative rivers in the Taihang Mountains in the western part of Hebei Plain, where the sedimentary subfacies (main facies, heart-beach facies, Side beach facies) sediment analysis of grain size, minerals and quartz surface structure.We know that mineral changes in river sediment is determined by many factors, but mainly the hydrodynamic conditions and Therefore, when explaining the changes of subfacies minerals, the main hydrodynamic characteristics such as bedding structure, grain size and quartz surface morphology are briefly introduced in the major subfacies of each section as ore
