深水异地沉积研究—回顾与展望

深水异地沉积是指在深水环境中经重力流或牵引流搬运、改造、沉积而形成的相对粗粒的沉积物，是深水重力流、等深流、内潮汐和内波沉积的总称。在重力流沉积和等深流沉积研究中，我国由向国外学习，到逐步达到国际先进水平；而在对内波、内潮汐沉积的研究中，我国学者在国际上首次鉴别出了古代地层中内潮汐沉积，并对其进行了系统研究，研究成果在国外权威学术刊物上发表后受到国际沉积界的重视，这标志着我国在这一领域的研究于世界

Study on Abyssal Allochthonous Deposits:A Review and Prospection

Abyssal allochthonous deposits consisting of density current, contour current, and internal tide and wave deposits are relatively coarser sediments transported and accumulated by density and contour current in abyssal environments. Some important progresses in studying systematically density and contour current deposits are made by the Chinese scholares, catching up with the world'S advanced levels.It is first time in the world that internal tide deposits from ancient strata are identified in our country. Their researches reported in an oversea authoritative academic journal are taken seriously by international sedimentological circles.It is shown that the our study in this field is in the lead of the world.
