摘　　要：坪宝地区位于南岭成矿带中段,是湘南有色金属重要矿田之一,成矿地质条件优越。自20世纪50年代开始,许多科研和生产单位在坪宝区内开展大量的地质物化探工作,积累了丰富的区带地质物化探资料和科研成果,但由于各种原因,近年来区内找矿工作尚未取得重大突破。为了取得找矿突破,寻找盲矿体,在认真总结和综合研究已有资料基础上,通过不断提取深层次找矿信息,获取区域成矿规律,对矿床和矿体的定位求得模式化和实效性,针对地质物化探异常特征进行综合研究,得到了五个找矿重点预测靶区,根据五个靶区进行分级,得出了大坊北区和宝山竹子岭区是寻找大中型铅锌银等多金属矿的有望地段,马鞍岭区是寻找中小型铅锌银矿床的有利地段,博石岭区是寻找金银矿床的潜力区。Pingbao area is located in the middle part of Nanling Mountains metallogenic belt,one of the most important non-ferrous metal fields in Southern Hunan.Since the 1950 s,many scientific research and production units carry out a lot of geophysical and geochemical prospecting work in Pingbao area.It has accumulated a wealth of regional geophysical and geochemical exploration data and scientific achievements.But for various reasons,in recent years,no great breakthrough has been made in the prospecting work in the area.In order to achieve a breakthrough in prospecting,and look for blind ore bodies,in this paper,on the basis of the previous data carefully summarized and comprehensive researched,by constantly extracting deep-seated prospecting information,to obtain regional metallogenic regularity,to obtain the model and the actual effect to the deposit and the ore body localization,the characteristics of geophysical and geochemical anomalies are comprehensively studied.Five key prospecting target areas have been obtained.According to the five target areas,it is concluded that the north district of Dafang and Zhuziling district of Baoshan district are promising areas for the exploration of large and medium-sized polymetallic deposits such as lead,zinc and silver.Maanling area is a favorable area for the exploration of medium and small scale Pb-Zn-Ag deposits,and Boshiling area is a potential area for searching for gold and silver deposits.
