摘　　要：北京市凤鸵梁 -四海地区燕山期岩浆活动强烈地质构造复杂 ,中生代地层划分问题一直争议颇多。本文作者在 1∶ 5万区域地质调查和对邻区的野外地质观察的基础上 ,建立了本区中生代地层的基本层序并提出将其划分为髫髻山组、后城组、东岭台组。The intensive Yanshanian magmatic activity and multiple-episode tectonic deformation resulted in a complex geology in the Fengtuoliang-Sihai area of Beijing Municipality.Therefore,there are many opinions about the classification of Mesozoic stratigraphic sequence the in this area.Based on the 1∶50000 scale geological mapping and the field observations in the neighbouring regions,we established the basic stratigraphic sequences for the Mesozoic volcano-sedimentary strata in Fengtuoliang-Sihai area,and divided the strata into Tiaojishan Formation,Houcheng Formation and Donglingtai Formation.
