COMPILATION AND EXPLANATION OF THE GEOLOGICAL MAP OF GRANITE IN NORTHEAST CHINA (1:1 500 000)

The Geological Map of Granite in Northeast China (1:1 500 000) is compiled on the basis of previous literatures and latest achievements of regional geological survey, with 1093 data of isotopic ages of granite, 772 groups of major element analysis data, 627 groups of microelement data and 653 groups of rare earth element data. The map highlights the role of tectonic granite zonation. By this study, the pre-Mesozoic tectonic granite is divided into 2 tectonic granite domains, including 2 tectonic granite provinces and 7 tectonic granite zones. The Meso-Cenozoic tectonic granite is divided into 2 tectonic granite domains, with 3 tectonic granite provinces and 7 tectonic granite zones. With this result, the spatial and temporal evolution characteristics of the granite are more obvious.
