内波沉积中双向交错层理形成机理的探讨

Study on the Generational Mechanism of Bidirectional Sedimentary Structure by Internal-Waves

摘要: 内波可以对海底的沉积物进行改造形成内波沉积，并且已在该类沉积中发现了明显的交错层理，但对其形成机理还未进行深入探讨。本文主要通过表面波和内波的比较，阐明了内波质点的运动特征，并结合海水的“稳定层化论”，剖析了内波沉积中双向交错层理的形成机理。

Abstract: Internal waves can transform the seabed sediments. People can find bidirectional sedimentary structure in this kind of internal-wave depositions. But its generational mechanism has not been studied deeply. Through the comparison of surface waves and internal waves, we can find the particle of internal-waves motion characteristics. Combining the theory of seawater “stable stratification”, the generational mechanism of bidirectional sedimentary structure by internal-waves may be clear.
