| 摘 要： | 根据不同比例尺的区域地质调查成果以及综合研究资料,吉林省中部早中生代火山事件地层可初步作如下划分:晚三叠大酱缸组沉积期自早而晚有:星星哨火山事件(229.5～227.5 Ma),官马火山事件(222±10)Ma,西土山火山事件(210±19)Ma;早侏罗世板石顶子组沉积期有:双丫子东山火山事件(195.04±5.01)Ma,官马金矿火山事件(193.6 Ma);早侏罗世太阳岭组沉积期有:未命名火山事件1(188.0±19.0)Ma,未命名火山事件2(184.0±1.1)Ma,北大湖火山事件(179.4±1.1)Ma,二道沟火山事件(174.0±34)Ma。

| Abstract: | According to the different scale regional geological survey and comprehensive research data,the middle part of Jilin Province in early Mesozoic volcano event stratigraphy can be preliminarily divided as follows: Late Triassic epoch Dajianggang Formation depositional stage since the early and late are as follows: Xingxingshao volcanic event(229.5-227.5)Ma,the Guanma volcanic event(222±10) Ma,Xitushan volcanic event(210±19)Ma.Early Jurassic Banshidingzi depositional period are as follows: the Shuangyazi Dongshan volcanic event(195.04 ±5.01)Ma,the Guanma gold mine volcanic event(193.6Ma),the Early Jurassic Taiyangling deposition period are as follows: the unnamed volcanic event 1(188.0 ±19.0) Ma,unnamed volcanic event 2(184.0±1.1) Ma,North Lake volcanic event(179,4 ±1,1) Ma,Erdaogou volcanic event(174.0 ±34)Ma. |
