摘　　要：湘东北醴陵地区是湖南重要的金矿田区。整个矿田金矿床受区域NNE向韧性剪切带和NW向劈理化带控制。团山背矿区土壤地球化学异常明显,显示多个异常中心,同时,其物探ΔT值异常分布显著。成矿类型为石英脉型和蚀变岩型两种金矿类型,通过分析其矿床成因及富集演化过程,认为团山背矿区东南部及深部具有较好的找矿前景。Liling area is an important gold ore field in Northeast Hunan.In the whole ore field gold deposits are controlled by the NNE-trending ductile shear zone and the NW-trending cleavage zone.The soil geochemical anomaly is obvious in Tuanshanbei mining area,showing multiple anomaly centers.At the same time,the geophysical prospectingΔT value anomaly distribution is obvious.There are two types of gold mineralization,quartz vein type and altered rock type.Through analysis of the genesis and enrichment evolution process of the deposit,it is considered that the southeast and deep parts of Tuanshanbei mining area have a good prospecting prospect.
