| 摘 要： | 20世纪50年代初期以来，沉积物重力流研究得到沉积学家们的广泛重视，特别是自60年代末期,与沉积物重力流密切相关的水下扇研究成为沉积学领域的热点。通过对国内外大量沉积物重力流及水下扇研究成果的总结，结合我国中新生代陆相断陷盆地水下扇发育的特点，将水下扇的组成岩相划分为基质支撑砾岩相，颗粒支撑砾岩相，砾质砂岩相，块状砂岩相，经典浊积岩相。水下扇的形成机制系重力流成因。内扇以杂基支撑，颗粒支撑砾岩组合为特征；中扇以砾质砂岩、块状砂岩组合为特征；外扇以CDE序及DE序经典浊积岩发育为特征。 |

| Abstract: | From the early days of 50s, 20th century, sediment gravity flows have been rec-ognized widely by sedimentologists ,especially from the end of 60s,submarine fan related nearly to sediment gravity flows has been the hotspot of sedimentology field. Through the summary of a large of research accompliments of sediment gravity flows and submarine fan China and abroad, integrated with the development characteristics of submarine fan in Cenozoic - Mesozoic rupture basins China, rock facies of submarine fan are classified into matrix cement conglomer-ate rock, grain surported conglomerate rock, conglomerate - sandstone, massive sandstone and classical turbidite. The formation of submarine fan related to sediment gravity flows. The char-acteristics of inner fan is combination of matrix cement conglomerate rock and grain supported conglomerate rock, middle fan is combination of conglomerate - sandstone and massive sand-stone,outer fan is classical turbidite. |
| Keywords: | submarine fan sediment gravity flows turbidite turbidity currents hydrody-namic mechanism |
