| 摘 要： | 吉林省铁、镍、钒、钛、钨、钼、金、银、铜、铅、锌、锑等内生金属矿产主要是晚印支—燕山期成矿事件的产物,已有测年数据拟建的成矿事件年谱所显示的结构特征表明：①、可划分出230～180 Ma、180～130 Ma、130～100 Ma三个时段和六个亚时区;②、180 Ma±、130 Ma±、100 Ma±的三大成矿峰期,均处于早期盆地闭合,新期盆地打开的转换期;③、三大成矿峰期由老而新主矿种由钼—金（银）—铜的演化。上述特征受该地质时期区域构造-岩浆作用和岩石圈的演化所制约。

| Abstract: | The iron, nickel, vanadium, titanium, tungsten, molybdenum, gold, silver, copper, lead, zinc, antimony and other metals in Jilin Province were mainly formed in the late Indo-ChinaYanshanian metallogenetic events, the data chronology of metallogenetic events show some characteristics; !. It can be divided into three stages - 230-180Ma, 180-130Ma, 130-100Ma and six substages;2. The 180Ma±, 130MaC,and 100Ma±, are main metallogenetic stages, they are all in the new transform period of the early closed basins and a new open basins. 3. The three metallogenetic stages show evolution from the old and the new, from molybdenum to gold （silver）, they are controlled by the regional structure and magmatism in these stages. |
