摘要
根据辽河岩群杨树沟岩组叠层石指向研究、盖县亚岩群晚期收缩阶段构造样式分析、辽河岩群南北区域地层特征对比以及南北区域差异的原始沉积探讨四个方面,进一步说明南北辽河岩群是相变而不是上。
Diffierences of Liaohe Lithogroup between the southern and the Northern regions are the results of facies Changing laterally within the same geological time but not owing to stratig raphic older and younger relationship. The conclution is based on the research of stromatolite younging direction in Yangshugou Lithoformation, analyses of the tectonic style of Gaixian Sub-lithogroup, stratigraphic correlation of Liaohe Lithogroup in both Southern and Northern regions, and studies of original sedimentary characteristics.
