郯庐断裂带在辽北地区三叠纪左行韧性剪切带的发现及变形特征

THE TRIASSIC LEFT-LATERAL DUCTILE SHEAR ZONE OF TAN-LU FAULT ZONE AND ITS DEFORMATION IN NORTHERN LIAONING PROVINCE

摘要: 郯庐断裂带位于辽北地区的部分为区域上郯庐断裂北延分支依兰-伊通断裂带的一段，在1：5万区调中发现有北东向展布的三叠纪左行韧性剪切带，此韧性剪切带控制一系列三叠纪侵入岩的分布并对古生代地质体的展布进行改造.

Abstract: The section of Tan-Lu fault zone in northern Liaoning Province, as a part of Yilan-Yitong fault zone, is actually the regional northward extension of the Tan-Lu fault zone. The NE-trending Triassic left-lateral ductile shear zone is discovered during the regional geological survey in 1:50000 scale. The ductile shear zone controls the distribution of a series of Triassic intrusive rocks and reforms the extension of Paleozoic geologic bodies.
