本文提出河流携带入海的沉积物或沿岸剥蚀物中矿物的分布及再组合是受多种因素控制的。为了确定控制鲁南两城河至白马河沉积物样品中矿物分布及再组合的主要因素,作者对该区109个沉积物样品的重矿物资料进行了Q型和R型因子分析。研究指出,在诸多的河流中,白马河和两城河是控制该区沉积物分布的最上要的河流;矿物的化学稳定性是决定该区矿物再组合的主要因素。
This paper proposes that the distribution and recombination of minerals in sediments or coastal erosion carried by rivers may be controlled by many factors. In order to determine the main factors that control the mineral distribution and recombination in the sediment samples from Liansheng River to Baima River in Lunan, Q-type and R-type factor analyzes were performed on the heavy minerals of 109 sediment samples in this area. The study shows that in many rivers, the Baima River and Liangcheng River are the most important rivers that control the sediment distribution in this area. The chemical stability of the mineral is the main factor that determines the re-combination of minerals in this area.
