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.
