【摘要】：等深流沉積研究已有約50年的歷史,其研究成果極為豐富。近10余年,隨著科學技術的發(fā)展和海洋意識的提高,等深流沉積研究工作開展迅速,涌現(xiàn)出了大量的新成果。簡要回顧了等深流沉積研究的歷程,結合最新研究成果,對其進展及認識進行了總結。等深流沉積以細粒沉積為主,沉積構造及生物擾動發(fā)育,多呈細—粗—細沉積序列。其類型可分為長條形丘狀漂積體、水道型漂積體、補丁型漂積體等7類。沉積模式根據(jù)地形、水動力、路徑等可分為簡單路徑模式、復雜路徑模式以及等深流與重力流交互作用模式。等深流與重力流交互作用是深水沉積研究熱點之一。等深流沉積研究面臨的問題及發(fā)展方向主要有三方面,即,1)完善識別標志,推廣研究成果;2)綜合運用多種手段和理論,探討沉積過程與構造演化、古海洋及氣候變化的耦合關系;3)加大油氣勘探潛力研究力度。
[Abstract]:The research on isothermal flow deposition has a history of about 50 years, and its research results are extremely rich. In the past 10 years, with the development of science and technology and the improvement of ocean consciousness, the research of iso-deep current deposition has been carried out rapidly, and a large number of new achievements have emerged. This paper briefly reviews the course of isothermal current deposition research, and summarizes its progress and understanding combined with the latest research results. The isothermal flow deposits are mainly fine-grained deposits with sedimentary structures and bioturbations, and most of them are fine-coarse-fine sedimentary sequences. Its types can be divided into seven types: long-shaped mound drift, waterway drift, patch-type drift and so on. The sedimentary model can be divided into simple path model, complex path model and interaction mode between isodepth flow and gravity flow according to topography, hydrodynamic force and path. The interaction between isotonic flow and gravity flow is one of the hotspots in deep water deposition research. There are three main problems and developing directions in the research of isothermal flow deposition: 1) perfecting the identification mark, 2) synthetically using various means and theories to discuss the sedimentary process and tectonic evolution. The coupling relationship between paleoocean and climate change is 3) to increase the research of oil and gas exploration potential.
