摘　　要：上升流是受地形、季风或大洋环流等作用而产生深层水涌升的一种洋流。在上升流活动区域极易形成缺氧强还原条件的富有机质沉积、硅质沉积和磷酸盐等沉积,可以作为油气烃源岩、硅藻土和磷矿等沉积矿床的有利探勘区带。因此,上升流沉积的研究引起石油地质学家及沉积矿床研究者的高度重视。笔者通过广泛阅读国内外上升流研究的相关文献,对当前上升流沉积研究的现状及发展趋势进行总结,以期对相关矿产,特别是对油气资源勘探提供指导。The upwelling was one of ocean currents induced by the deep water swelling upward by terrain,monsoon or ocean circulation.The active upwelling areas could form strong redox and anoxic conditions beneficial for developing anerobic and strong reducing organic and silican-enriched sediments,and they were favorable exploration areas of resource rocks,diatomite,phosphorite and other sedimentary deposits.Therefore the studies of upwelling sediments were drawn high attention from petroleum geologists and sedimentologists.Through extensive studying the related documents on upwelling sediments both from the home and abroad,the present research situation and development tendency are summarized in order to supply a theoretical basis for exploration of oil or other mineral resources.
