| 摘 要： | 本文根据国内外等深流及其沉积的研究成果,概述了它们的研究进展,且详细阐述了等深流沉积特征和沉积类型,并指出等深岩丘的发现是该领域最为重要、最具特色的突出成果以及等深流沉积研究的油气勘探意义.虽然随着深海钻探计划和大洋钻探项目的开展,等深流沉积研究取得了较大进展,但现代等深流沉积和古代等深流沉积的研究在一定程度上发展尚不平衡,仍存在着较多问题,尤其是在古代等深流沉积研究方面显得更为薄弱.最为重要的是,等深流沉积的识别是该领域研究的最大难题.因此,在其未来研究上,应注意运用地震波识别、遥感等现代科技调查手段,进行多学科综合研究,尽快建立一套完善的识别标志,如沉积学标志、古生物标志等,以促使其逐渐成为海洋沉积学中一个更为完善的研究领域.

| Abstract: | This paper briefly introduces the envolvement of contour current and contour current deposits. Their sedimentary characters and types are expatiated.It is pointed out that the discovery of contour drifts is the most important anddistinctive achievement in this field and the contour current deposit study is significant in oil and gas exploration. Although contour current deposit study has made great progress along with the development of DSDP and of ODP,the researches on modern and ancient contour current deposits are imbalanced to a certain extent and have many problems, especially in the study of ancient contour currentdeposit. Above all, the discrimination of contour current deposits is the most crucial problem. Therefore in the future, we should synthesize multidisciplinaryapproaches with identification of seismic wave, remote sensing,etc., and establish some effective discriminating indicators such as sedimentary markings and paleontological markings, so as to advance its research ulteriorly and make it to be a more perfect research field in the marine sedimentology. |
