摘要
依据中国东部已发现的两种不同类型的末次冰期风沙沉积剖面,总结出空间分布上的局限性,类型上的多样性,序列上的旋回性,盛行风向的恒定性,物质组成的近源性,伴生物的一致性,层理类型的典型性,序次界面的特定性以及控制因素的一致性等十大特征,并提出了风沙沉积的相模式。
On the basis of two different types of last-glacial sedimentary sections of windblown sands found in eastern China, this paper not only gives the facies model of windblown sand deposits, but also suggests their nine characteristics as follows: limit in spacial distribution, diversity of types, cyclicity of sequence, relative constancy of prevailing wind directions, proximal components, the same associated materials, typicalness of beddings, special hierarchies of bounding surfaces and uniform controlling factors.
