Abstract

It was previously considered that Huapigou and Dalidai pluton pluton located in the Chenming area, Heilongjiang Province, respectively consist of Hercynian and Proterozoic granites. However, the authors defined the emplacement ages of Dalidai pluton and Huapigou pluton by LA-ICP-MS zircon U-Pb dating and obtained ages of 453.5±6.0Ma and 454.8±2.6Ma, which suggest that these granites are a part of Early Paleozoic granites located in the Yichun-Yanshou tectonic belt instead of the Hercynian and Proterozoic granites as previously believed.
