| 摘 要： | 华北北部中、上元古界具大陆裂谷沉积特征，地层自下而上分三种沉积类型，反映大陆裂谷的三个发展阶段。１．碎屑岩一火山岩活动沉积类型，反映裂谷早期拉张和火山活动阶段的沉积特征，包括常州沟组、串岭沟组、团山子组、大红峪组。２．碳酸盐岩活动沉积类型，反映裂谷强烈下陷、拓宽、广泛海侵阶段的沉积特征，包括高于庄组、杨庄组、雾迷山组。３．碎屑岩一碳酸盐岩稳定沉积类型，反映裂谷活动期后，稳定残余凹陷的沉积特征，包括洪水庄组、铁岭组、下马岭组、龙山组和景儿峪组。根据裂谷发展阶段及其沉积类型，华北北部中、上元古界可划分为：长城群（常州沟组、串岭沟组、团山子组、大红峪组）；蓟县群（高于庄组、杨庄组、雾迷山组）；青白口群（洪水庄组、铁岭组、下马岭组、龙山组、景儿峪组）。

| Abstract: | Middle-Upper Proterozoic stratum in the northern part of north China have thesedimentary origin in failed rift. The sequence, from bottom to top, may be divided into threekinds of Sediment and three developmental stages: 1. Active elastic sediment volcanic rocks wereformed in the early stage of the tension and volcanic activities occurred in the failed rift, includingChangzhongou F., Chuanlinggou F., Tuanshanzi F. and Dahongyu F.. 2. Active Carbonaterocks were formed at the stage of sharp falling and widen and transgression widely of the failedrift, when dePOsited Gaoyuzhuang F., Yangzhuang F. and Wumishan F.. 3. Stable elasticsediment Carbonate rock were formed at the stage when the rift to be seased after activedevelopment of rift. During this stage deposited the Hongshuizhuang F., Tieling F., XiamalingF., Longshan F. and Jingeryu F.. According to the developing stages of the failed rift, theMiddle-Upper Proterozoic in the northern part of north China may be divided into three groups:The Changcheng Group including Changzhougou F., Chuanlinggou F., Tuanshanzi F. andDahoflgyu F.. Jixian Group including Gaoyuzhuang F., Yangzhuang F., Wumishan F..Qingbaikou Group: Hongshuizhuang F., Tieling F., Xiamaling F., Longshan F. and JingeryuF.. |
