摘要
Based on the 1∶50 000 and 1 ∶250 000 regional geological survey in Jiayin, Yichun, Hegang, Jixi and Mudanjiang areas in recent years, with the concept of tectonic assemblage of igneous rocks, a preliminary plan on the division of Paleozoic tectonomagmatic stage is put forward, according to the zircon U-Pb age of the intrusive rocks. Based on the study, the Caledonian tectonomagmatic stage and middle Variscan-Indosinian tectonomagmatic stage are set up. The point, which is different from the traditional view, will provide a new access to understand the tectonic evolution of this region.
