摘    要:从岩石组合、沉积序列、接触关系及变形变质方面分析辽东隆昌地区的辽河群是一套在沉积上连续的,并且经历了相同变形变质历史的中浅变质沉积岩系。详细的构造分析表明它经历了三期构造变形,第一期为北北西向平褶皱,第二期为北北四向斜歪褶皱,第三期为北东东向宽缓直立褶皱。

关 键 词:辽河群  构造样式  构造演变  隆昌  辽东

Abstract:Based on the study of the features of rock assemblages, sedimentaly sequences and metamorphism-deformation in Liaohe Group, Longchang area of East Liaoning, it is suggested that the Liaohe Group is a Continuous meta-sedimentary stratum which is of the same history of metamorphism-deformation. The detailed structural analysis shows that the Liaohe Group underwent three episodes of deformation, that is,the first characterized by NNW trend recumbent folding with development of axial plane schistosily,the second by NNW trend recline folding with appearence of crenulation cleavage and the last by NEE trend upright broad folding with penatrative structures.
Keywords:Liaohe Group Structural patten Structural evolution Longchang East Liaoning
