| 摘 要： | 在横穿辽西地区构造变形剖面及重点区段的详细构造解析的基础上 ,结合构造变形、沉积组合、岩浆岩特征及同位素年代学等资料 ,对辽西地区中生代以来的总体构造格局进行了厘定 ,认为辽西地区中生代主要构造格局由印支期的东西向褶皱 -逆冲构造、早燕山期的北东向叠瓦状逆冲推覆构造、晚燕山期早期的北东向“盆 -岭”构造、晚燕山晚期的北北东向左行走滑构造组成

| Abstract: | Based on the study of two major cross-sections in the westernLiaoning Province,the tectonic framework of the western Liaoning Province consists of four kinds of fault systems with different orientation and deformation time:(1)east-west-trending reverse faults and folds of the Indosinian epoch,(2)northeast oriented imbricate thrust system of the Early Yanshanian,(3)northeast-north striking “basin and range”-type system of the early stage of the Late Yanshanian epoch,(4)north-to northeast trending sinistral strike-slip fault system of the Late Yanshanian epoch. |

| Keywords: | tectonic framework imbricate thrust fault basin range structure Mesozoic western Liaoning Province |
