| Abstract: | Based on the isotopic age data: U-Pb is 1 768Ma, 1 717Ma; K-Ar is 1 670Ma, 1 530Ma and 1 316Ma, it is believed that the Shanzuomiao sequence intrusive rock in Jianping arca is formed in the same period with extrusive rock of the Dahongyu Stage, Changchcng Period, Middle Proterozoic, as the product of Xingcheng uplift, Yanliao tectonic cycle. |
