| 摘 要： | 在我国西部山区广泛发育和分布第四纪大型复杂松散堆积体,这是一套介于土、岩之间的过渡类型的地质体;其成因复杂,主要包括残坡积物、崩滑堆积体、冲洪积物、冰碛物和冰水沉积物等两种或多种组合混杂堆积,明显区别于东部平原区的单一成因类型。本文通过资料对比分析,对大型复杂松散堆积体的一般特征、主要类型和区域分布规律进行了系统总结,最后从耦合的角度来探讨其成因机制,并提出河谷型松散堆积体的内外动力耦合概念模型,研究认为大型复杂松散堆积体属于典型的内外动力耦合作用产生的多期次、成因复杂的复合地质体。

| Abstract: | There are a lot of large-scale loose complex Quaternary deposits originated from landslide deposits,weathering residues,alluvial and flood deposits,drifts and glacial deposits etc.prevail in the west mountainous regions of China.These multi-origin deposits of a transitional type geological-body are distinctly differing from the single-origin loose deposits in the East plain regions of China.Based on the study of contrast analysis of deposits,this paper summarizes the basic features,main types and distribution rule.Lastly,this paper analyzes the geological origin of deposits from a coupling idea,and puts forward a coupling model of the Earth's geological processes of large-scale loose deposits of river valley.The analysis shows that the large-scale complex deposits belong to multi-order,complex composite geological body of the coupling of Earth's endogenic and exogenic geological processes.This study can provide with theory evidences for environment,geological hazards and project security. |
