摘要

摘要: 断陷湖盆中层序发育、演化取决于相对湖平面(可容空间)的变化和沉积物供给。相对湖平面上升时,湖浪能量增加,湖水向物源方向推进,形成水进型扇三角洲,水进滩坝和滑塌型浊积岩体较发育;相对湖平面下降时,湖水活动急剧减弱,河流能量增强,形成水退型扇三角洲,分流河道砂、砾岩体最为发育,同时也可形成高位滩坝砂、砾岩体和洪水型浊积岩体。在层序不同演化阶段,沉积环境的水动力能量状况有所不同,所形成的砂、砾岩体在平面上的构型有较大差异。

Abstract: Sequence development and evolution are determined by relative lake level(accommodation) change and sediment delivery in rift-subsidence lake basin.When relative lake level rises,wave energy increases,lake water prograds toward source area,lake-transgression beach and bar and slumped turbidite increases and lake-transgression fan-delta is formed.When relative lake level dropps,wave energy decreases,fluvial energy increases,lake-regression fan-delta ias formed,sandstone and conglomerate of distributary river course develop,and beach and bar of HST and flood turbidite are formed.Because that hydrodynamic force energy of sedimentary environment in different stages of sequence evolution is different,distribution of sandstone and conglomerate is different.
