摘    要:利用14条露头剖面和部分钻井岩芯、测井及地震剖面资料,从川西坳陷蓬莱镇组中划分出冲积扇、河流、三角洲、扇三角洲、湖泊和湖底扇6种沉积体系,并对各沉积体系的主要特征进行了较为详细的描述,分析和总结、归纳了各沉积体系的时空展布规律及其与湖泊扩张、收缩的响应关系

关 键 词:川西坳陷  蓬莱镇组  上侏罗统  沉积体系  剖面结构  时空配置

Abstract:According to the research of fourteen basset profiles, part of well core logging, log data and seismic section, the Upper Jurassic Penglaizhen Formation developed in West Sichuan Sag may be divided into six sedimentary systems, such as alluvial fan, river, fan delta, lake delta, lacus and sublacustrine fan. In this paper , the authors describe and analyse the main depositional sequence, genetic feature and distribution of the different sedimentary systems in the formation. The conclusion is that the time\|space allocationl rules of the six systems respond to expanding or contracting of the lake.
Keywords:West Sichuan Sag  Penglaizhen Formation  Upper Jurassic  sedimentary system  profile section  time\|space allocation
