| 摘 要： | 本文论述了分布于吉林省九台市土们岭－八台岭－马大山一带原划归晚二叠世马达屯组的一套火山岩的特征、年代、以实际材料为依据废弃马达屯组。将该套火山岩与双阳地区的晚三叠世小蜂蜜顶子组对比。讨论了这套火山岩的岩石学，岩石化学及地球化学特征。反映这期火山岩为造山带火山岩，火山岩浆为深源岩浆，该火山喷发带受北东向深断裂控制。对新发现的冷冻厂，头道沟火山机构进行了描述，阐述了该期火山岩与成矿的关系。

| Abstract: | In this paper,a set of the former volcanic rock characteristics of the late Permian Madashan Formation are discussed for the Tumenling-Batailing-Madashan areas,Jilin province. On the basis of the practical geologic data, the Madatun Formation is discarded;the volcanic rock is contrasted with the late Triassic Xiaofengmi Dingzi Formation in the Shuangyang area,Jilin province,and their petrography,petrochemistry and geochemical characteristics are discussed ,showing that the volcanic rocks are orogenic rocks;volcanic magma came from the deep;the volcanic eruptive belt is controlled by the EN deep fault;and the Lengdongchang-Toudaogou volcanic apparatus discovered recently is described,meanwhile, the relation bstween volcanic rock and ore-forming is discussed. |
