| 摘 要： | 深水牵引流沉积研究，是沉积学研究中一个较新的领域。在这个领域中，我国学者做出了应有的贡献，并且具有自己的特色和优势。目前研究的深水牵引流沉积，一是等深流沉积，二是内波、内潮汐沉积。等深流沉积研究开始于20世纪60年代，早期主要是对小规模的细粒薄层等深流沉积的研究，而现在已发展到对大规模等深流沉积体--等深岩丘的研究。内波内潮汐沉积研究始于20世纪90年代，也是从小规模内波、内潮汐沉积的鉴别开始，现在已达到研究深海大型沉积物波的阶段。今后等深流沉积研究的主攻方向，应是地层记录中的等深岩丘，并特别注意碎屑岩等深岩丘的发现和研究。内波、内潮汐沉积方面，最有矿产意义的当属由大型沉积物波构建的地质体。而首例地层记录中的大型沉积物波，已在塔里木盆地中部奥陶系中被鉴别出来，并具有含油气远景。从目前对内波、内潮汐的研究势头来看，我国很有希望在该领域继续保持国际领先地位。

| Abstract: | Deep-water traction current research is a comparative new domain of sedimentology. China scholars did contribution in this domain and have advantage and peculiarity in it. Deep-water traction current deposits mainly include two types, contour current deposits, internal-wave and internal-tide deposits. Contour current has been studied since the early and middle part of 1960’s. Early research was mainly refers to fine, lamina and small-scale contour current deposits. Now the advanced development have related to broad scale contour lithohermic body of lithoherms research. Internal-wave and internal-tide research began in 1990’s. Early research start with discriminating internal wave and internal tide deposits of small magnitude and now is the stage of study of large-scale sediment waves on deep-sea bottom. The main effort of future contour current research should put on the contour lithoherms in the stratigraphic record, particularly discovering and studying of contour lithoherms made of clasolite. The geologic body of inter-wave and inter-tide that have most mineral value is made of large sedimentary-waves. The first large sedimentary-wave has been discriminated in middle Ordovician system in Tarim Basin and find out it is hydrocarbon potential. View the situation of internal-wave and internal tide, China is likely keep leading in international in this domain. |
