| 摘 要： | 在都是沉降接受沉积的构造背景下,低弯度河的细段、粗段的沉积厚度比可比曲流河的大。决定因素有构造背景、气候、古地貌、古水文及它们的组合。这些因素及这些因素的组合反映,不仅控制了河流的性质,也控制了岩相类型、层序及沉积体的内部结构。

| Abstract: | On the basis of detailed study of petrology, sedimentary structures, sequences, configurationsof sand bodies, palaeohydrology and palaeocurrent, it is clear to identify meandering stream and low-sinuousity stream deposition, and easy to find that the thickness ratio of fine member and coarse mem-ber of low-sinuousity stream is higher than that of meandering stream being abnormal with usual situa-tion. The ratio of fine member and coarse member of meandering and low-sinuousity facies is relatedwith tectonic setting, climate, palaeogeomorphology and palaeohydrology. The complex of these factorscontroles the property of channel and its water systems. |
