摘要
在收集前人资料和最新区调及科研成果文献的基础上,梳理厘定公开发表文献的花岗岩岩体同位素年龄数据1093个,硅酸盐数据772套,微量元素数据627套,稀土元素数据653套.依据这些数据及最新调查成果编制东北地区花岗岩地质图(1∶1 500 000).该图突出了构造-花岗岩区划作用.此次研究将前中生代构造-花岗岩类划分为2个构造花岗岩域、2个构造花岗岩省和7个构造花岗岩区(带),将中新生代构造-花岗岩类划分为2个构造花岗岩域、3个构造花岗岩省和7个构造花岗岩区(带),使得花岗岩类的时空演化特征更加明显.
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.
