Abstract: With study on the chronogenesis of Mesozoic metallogenesis and magmatic activities in Northeast China, the chronologic framework of metallogenesis in Mesozoic era is established. The Mesozoic metallogenesis is centralized in two stages of 130-100 Ma and 200-160 Ma. The Mesozoic magmatic activities are chronologically subject to Late Mesozoic era, especially in the periods of 190-155 Ma and 135-115 Ma. There is a correspondence of chronogenesis between the metallogeny and magmatic activity in Mesozoic era.
