摘　　要：内波及内潮汐沉积是深水沉积研究中的一个非常年轻的研究领域,从首次发现内潮汐沉积至今仅20年时间,中国学者在这期间做了不懈的努力,取得了不少研究成果。简要地论述了中国在内波及内潮汐沉积研究方面的历程和取得的主要成果;重点介绍了已发现的内波及内潮汐沉积的特征、沉积层序、微相类型和沉积模式;指出了当前该研究领域中存在的问题,认为应及时并尽可能地将海洋物理学的相关研究成果应用在内波及内潮汐沉积研究中,进而利用地层记录中内波及内潮汐的沉积特征反演内波及内潮汐的物理特征,同时尽可能地开展内波及内潮汐沉积的水槽实验研究,探索其沉积机理。The study of internal-wave and internal-tide deposits is a very new research field in the deep-water deposition.It is just twenty years since the first example of internal-wave and internal-tide deposits was found in stratigraphical record.During this period,the Chinese scholars have made unremitting efforts and gained some research achievements.This paper expounds briefly the research history and the main achievements of the internal-wave and internal-tide deposits in China,and mainly introduces the characteristics,sedimentary successions,types of microfacies,sedimentary model of internal-wave and internal-tide deposits which have been identified,and points out the existing problems in this research field.The relative achievements of the marine physics should be applied to the research of the internal-wave and internal-tide deposition,and the sedimentary characteristics will be used to inverse the physical characteristics of the internal-waves and internal-tides.Also the flume experiments of the internal-wave and internal-tide deposition should be put in practice as often as possible so as to recognize the mechanism of internal-wave and internal-tide deposition.
