摘要
本文对燕山地区蓟县纪～青白口纪的层序地层学问题作了初步研究。着重描述了各组、段岩石的基本层序特征和沉积体系域，共划分出两个Ⅰ型层序和一个Ⅱ型层序，并对岩石地层格架作了初步的解释。
We have preliminarily studied the sequence stratigraphy of the Jixian-Qingbaikou Periods in Yanshan area,emphatically discribed the essential sequence features of every Formation and Member and their depositional systems tracts.In this paper,twoⅠ-typed and one Ⅱ-typed sequences are subdivided and the prelim explanation is given on the lithostratigraphic framework.
