摘要
侏罗纪时期,河流作用是最主要的地质营力,在适宜的构造条件下,发育了2000多米厚砂质河流沉积。根据1:5万区调资料分析,将砂质河流环境划分为三大亚环境和四种沉识类型,并对每一种类型确立了沉积序列,叙述了自身独有的特性。
The fluvial action was the main geological agen in Jurrassic and the sandy fluvial sediments, which were more than 2000m thick, were developed in the suitable tectonic condition. According to the analysis of a great unmber of data collected from the 1 :50000 scale regional geological survey, we suggest that the sandy fluvial environment can be divided into three big subenviron-ments and four sedimentary types, with a vsedimentary sequence for each type established and its unique characteristics expounded.
