中文摘要
本文在露头分析的基础上,对粗粒沉积波型矿床的沉积过程进行了研究。矿床具有(1)基底槽状构造;(2)波陡为0.035 ~ 0.08,波长为3 ~ 100 m,波高为0.2 ~ 2 m的对称形态;(3)前置、后置、槽状交错层理;(4)波形不是侵蚀作用的产物。因此,粗粒度的沉积物-波浪沉积物被认为是在浊流中密度较大的底流和密度较小的上层流之间的界面上由波浪形成的下游迁移的砾石反沙丘。
英文摘要
The present study aimed to clarify depositional processes of coarse-grained sediment-wave deposits on the basis of outcrop analyses. The deposits have (1) flute structures in the bases, (2) symmetrical form with the wave steepness of0.035-0.08, the wave length of 3-100 m, and the wave height of 0.2-2 m, (3) foreset, backset, and trough cross bedding, and (4) the waveforms were not the product of erosional processes. Consequently, the coarse-grained sediment-wave deposits are thought to have formed as downstream-migrating gravel antidunes that formed by waves at the interface between the denser bottom-flow and the less-dense upper flow within a turbidity current.
