| 摘 要： | 利用板块构造理论，依据近年来1：5万区域地质调查及相关科研成果，对辽宁地壳发展演化进行了分析研究，提出辽宁地壳发展可暂划分为早前寒武纪大陆增生构造体制和中元古宙以来的板块构造体制.中太古代-古元古代发现了绿岩地体和古元古宙裂谷，因此将早前寒武纪视作原始板块，中元古代-古生代视作古板块，中生代以来视作现代板块.在此基础上对辽宁大地构造单元进行了划分.辽宁Ⅰ级构造单元为塔里木-华北板块.Ⅱ级构造单元为天山-赤峰陆缘活动带和华北陆块.Ⅲ级构造单元5个，分别为建平-西丰华力西陆缘造山带、冀辽地块、铁岭-清原微地块、辽吉地块及下辽河-辽东湾新生代裂谷.Ⅳ级构造单元16个.为清楚地了解辽宁地壳发展演化特点，对5个Ⅲ级构造单元地质特征进行简要阐述.

| Abstract: | Based on the theory of plate tectonics and the results of the 1:50000 regional geological survey in recent years and related achievements,the crustal evolution and development of Liaoning region are analyzed.It is suggested that the crustal development in the region should be divided into Early Precambrian continental accretion tectonic system and Mesoproterozoic plate tectonic system.Because of the discovery of the Mesoarchean-Paleoproterozoic greenstone terrane and Paleoproterozoic rift,the Early Precambr... |
