摘要
在综合研究野外露头、钻井剖面及室内编图、地层对比的基础上 ,指出鄂尔多斯盆地冲积扇 -河流沉积体系是侏罗纪富县期主要的古地理格局 ,富县期沉积受与古地貌密切相关的五条河谷控制。认为鄂尔多斯盆地侏罗纪富县期冲积扇沉积具进积型特征 ,其形成与古地形密切相关 ,分布于古甘陕。
Based on the synthetic study of field outcrops, drilling section data, charts drawn in rooms, and data of stratigraphic correlation, the authors propose that the paleogeographic pattern of Ordos Basin was a fan fluvial sedimentary system at Jurassic Fuxian Stage. The deposition of Fuxian Formation was controled by five river valleys closely related to paleogeomorphology. There were fans undoubtfully at Jurassic Fuxian Stage and the fans located in Ganshan and Qingxi river valleys show the progradating characteristic .
