摘要:
东北地区1:150万大地构造相图是2018年出版的一份区域性大地构造图.该图依据不断积累和丰富的基础地质资料,将大地构造理论研究与综合应用汇总和集成,是东北地区科技创新成果和技术方法进步转化应用的重要体现.此次编图以板块构造理论和大陆动力学思维为指导,以多岛洋、弧-盆系发展演化观点为切入点,运用大地构造相分析方法,研究东北地区地壳形成、演化历史,以及大地构造环境及其与成矿作用的时空关系.较系统地阐述了东北地区的岩石构造组合、建造构造与构造演化阶段的宏观背景.
Abstract:The 1:1 500 000 Tectonic Facies Map of Northeast China is a regional geotectonic map published in 2018. Based on accumulated abundant basic geological data, the map summarizes and integrates geotectonic theory study and comprehensive application, which is an important embodiment of scientific innovation achievements and technical progresses transformed to application in Northeast China. Guided by the theories of plate tectonics and continental dynamics, starting from the development and evolution of archipelagic ocean and arc-basin system, the map compilation applies the tectonic facies analysis method to study the crustal formation, evolution history, and geotectonic environment as well as its spatial-temporal relation with mineralization in Northeast China. It systematically expounds the macro-background of rock tectonic associations, formation structures and tectonic evolution stages in Northeast China.
