Abstract

Thick Neoproterozoic strata are widespread in the Dalian region, Liaodong Peninsula, Northeast China. SHRIMP zircon U-Pb dating of dolerite intruded into Neoproterozoic strata gives its emplacement age as 211±2 Ma. However, abundant 0.9-1.1 Ga zircons are identified in the dolerite. The age of 1125±38 Ma corresponds with the Grenvillian collisional event. The zircons of 904±15 Ma ages have high Th/U ratios (1.31-2.25) and magmatic oscillatory zones, being possibly related to later magmatism induced during amalgamation of Rodinia.
