摘　　要：对中国东北地区中生代区域成矿时序和岩浆活动时序及其对应性的分析表明，区域成矿作用总体上集中发生在150～100Ma和240～160Ma两大阶段，中生代的岩浆作用主要发育在190-155Ma和135～100Ma两个时段，二者在时序上具有良好的对应性，表明岩浆作用对区域成矿具有重要控制作用．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.
