摘要/Abstract

摘要： 大连地区褶皱构造式样及叠加变形现象极其丰富。本文从构造解析入手,运用微观构造与宏观构造相结合方法,详细划分了该区中生代的韧性变形构造期次,并研究和确定了各期的变形机制及变形式样,提出印支晚期南北向挤压变形为该区中生代发生的第一期韧性变形构造事件。在对全区资料综合分析基础上,重新厘定了研究区的构造格局。

关键词: 大连, 中生代, 韧性构造变形

Abstract: There are numerous folding and superimposed deformation styles in the Dalian area. By using the method of combining microstructural with macrostructural analyses, we make episode division for the ductile deformation of Mesozoic time in this area. We also determine the deformation mechanisms and patterns for each episode. It is suggested that the NS compressive deformation in late Triassic Period is the first ductile event of Mesozoic time in this area. On the basis of data analyses for the whole study area, the new tectonic pattern of the Dalian area is proposed.

Key words: Dalian area, Mesozoic time, Ductile tectonic deformation
