摘要: 等深流沉积研究已有约50年的历史，其研究成果极为丰富。近10余年，随着科学技术的发展和海洋意识的提高，等深流沉积研究工作开展迅速，涌现出了大量的新成果。简要回顾了等深流沉积研究的历程，结合最新研究成果，对其进展及认识进行了总结。等深流沉积以细粒沉积为主，沉积构造及生物扰动发育，多呈细-粗-细沉积序列。其类型可分为长条形丘状漂积体、水道型漂积体、补丁型漂积体等7类。沉积模式根据地形、水动力、路径等可分为简单路径模式、复杂路径模式以及等深流与重力流交互作用模式。等深流与重力流交互作用是深水沉积研究热点之一。等深流沉积研究面临的问题及发展方向主要有三方面，即，1）完善识别标志，推广研究成果；2）综合运用多种手段和理论，探讨沉积过程与构造演化、古海洋及气候变化的耦合关系；3）加大油气勘探潜力研究力度。

Abstract: There have been abundant research fruits on contourites for about 50 years. The work on the contourite are developed rapidly with technique and ocean awareness improving in recent 10 years, and hence, lots of new achievements have been emerged. Based on reviewing the research history of contourites in brief, combing the latest research results, the advance and achievement has been summarized. Contourites showing fine-coarse-fine cyclicity is usually fine, whose sedimentary structures and bioturbations are abundant. Based on morphology and sedimentary process, the contourites could be divided into elongated, mounded drifts, channel-related drifts, patch drifts and so on. The sedimentary model includes simple current pathway, multiple current pathway and down-slope and along-slope interaction. Furthermore, interaction between down-slope and along-slope is one of the hot spots of deepwater deposits research. At last, the facing problem and direction of work on contourites in the future were proposed as follows:1) Perfecting identification marks and popularizing research results. 2) Integrating various measures and theories, discussing the coupling relationship between sedimentary processes and tectonic evolution, paleoceanography, climate changing. 3) Reinforce to work potential of hydrocarbon exploration.
