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.
Based on the collection of the previous data and the latest research results and the literature of scientific research achievements, we sorted out 1093 isotopic age data of granite rock mass, 772 sets of silicate data, 627 sets of trace elements data and 653 sets of rare earth elements data Based on these data and the latest survey results, a geologic map of granites in the northeastern region was prepared (1: 1 500 000), highlighting the tectono-granitoids division.The study divided the pre-Mesozoic tectono-granitoids into two tectonic granites, Two tectonic granitic provinces and seven tectonic granitic zones (belts). The Mesozoic-Cenozoic tectono-granitoids are divided into two tectonic granitic areas, three tectonic granitic provinces and seven tectonic granite areas (belts) The characteristics of temporal and spatial evolution are more obvious.
