Based on the previous geological work, a large number of granitoid samples are carried on the Sm-Nd isotopic analysis. The results show that the εNd values of these granitoids occurred in Beishan Mountain area range from-16. 39 to +10. 89, some of which are characterized by the positive εNd value. It suggests that the crustal growth existed during Phanozoic in Beishan Mountain area, just like other regions in the CAOB.
本文在以往工作基础上,通过大量的Nd同位素分析,发现北山地区花岗岩类的εNd值变化于-16.39~+7.85,不少花岗岩类具正εNd值,说明本区与中亚造山带上其他地区一样,在显生宙存在大规模的地壳生长。

We divide the evolution of becoming rocks into four periods: early region's metamorphic process and mixed lithifaction,sedimentation and becoming rocks process in middle and late Proterozonic Era and in the Paleozonic Era,trasformation process of burial hill layers in earth shell'uplift period in the Mesozonic Era, and transformation process to burial hill in the Cenozonic Era.
