摘　　要：笔者通过近年来在吉林省洮南金蟾一带的地质勘查工作,大致查明了本区的地层、构造、岩浆岩分布特征,分别圈定综合异常10处、圈定5条北东向视极化率异常带、高磁异常8处、断裂构造5条,并且新发现矿(化)体16条。结合成果实际材料,综合研究发现本区的矿(化)体与物化探异常形态相吻合,物化探异常形态与本区北东向断裂构造、北西向次级构造方向大致吻合,进一步验证了该地区找矿远景及潜力。通过成果实际材料研究比对,初步认为矿(化)体的存在与区域内发育的火山岩、断裂构造有着密切的因果关系。Through the recent geological exploration work in Jinchan area of Taonan,Jilin Province,the strata,structure and magmatic rock distribution characteristics of this area are roughly identified,and 10 comprehensive anomalies,5 northeast apparent polarization anomaly zone,8 high magnetic anomalies,5 fault structures are delineated,and 16 new ore(chemical)bodies are discovered.Based on the actual materials,through comprehensive research,the authors found that the mineral(chemical)bodies in the area ara consistent with the abnormal forms of geophysical and geochemical exploration.The abnormal forms of geophysical and geochemical exploration are roughly consistent with the northeast fault structure and northwest secondary structure in the area,which further verified the prospecting prospect and potential of this area.Through the actual material research and comparison of the results,it is preliminarily concluded that the existence of mineralization(chemical)bodies has a close causal relationship with the volcanic rocks and fault structures developed in the region.
