深水斜坡水道中形成的沿道向上或向下方倾斜的交错纹理或交错层理是水道型内潮汐沉积的典型沉积构造,特别是深水沉积中的双向交错层理是内潮汐沉积中最为典型的特征。内波与表面波主要差异仅是单位海水质点回复力,因而本文依据内波和表面波相似的运动特征,用一般意义上的波动理论来分析内潮汐沉积中双向交错层理的形成机理。
The staggered texture or staggered bedding, which is inclined upward or downward along the channel, is a typical sedimentary structure of tidal sediments in the channel. The two-way interlacing strata especially in deep water sediments are the most typical features of the tidal sediments. The main difference between internal waves and surface waves is only the sea-water point resilience. Based on the similar motion characteristics of internal waves and surface waves, this paper analyzes the formation mechanism of two-way interlacing stratification in the tidal sediments in the general sense of the wave theory.
