摘　　要：千子岭铅锌矿是江西省近10年在空白区勘查发现的一处中型铅锌矿床,提交铅锌金属量23万余t。产于萍乡-广丰深断裂带中,伴生有铜、银和萤石,属于破碎带蚀变岩型铅锌矿床。文章归纳矿床地质特征,介绍了勘查过程,总结了千字岭矿区勘查突破的经验。从搜集老资料和调研炉古岭铅锌矿点入手,抓住成矿地质作用留下的微弱化探异常和无矿"硅帽",对物探测量和异常解译,先找地质体,进而布置工程验证,实现了找矿突破。The Qianziling lead-zinc deposit is a medium-sized lead-zinc deposit produced in the Pingxiang-Guangfeng deep fault zone,accompanied by copper ore and fluorite deposits,and belongs to the altered rock type lead-zinc deposit in the fracture zone.The article briefly summarized the geological characteristics of the deposit,focused on reviewing the exploration process,and summed up the experience and inspiration of breakthroughs in the exploration of Qianziling mining area. The project team started by collecting old data and investigating the Luguling lead-zinc deposit,and firmly grasped the weak geochemical anomalies and non-ore "silicon caps"left by the ore-forming geology,and the geologists and geophysical personnel jointly participated in the detection and anomalies Interpretation,first find the body in prospecting,unremittingly explore and verify,and arrange project verification step by step;investors’ outstanding sense of district selection and continuous and patient input make prospecting successful.
