摘　　要：凡口铅锌矿是粤北地区超大型铅锌矿床,发育独特的覆盖区复杂地质环境。本文以凡口铅锌矿为例,在前人研究的基础上,应用高精度磁法、可控源音频大地电磁法、土壤电吸附、氡气、吸附烃-汞气体测量、及导电率等多种物化探勘查技术。通过对凡口矿床及外围进行对比分析和研究,建立凡口矿区有效探测技术集成,优选方法组合为高精度磁法、CSAMT、土壤吸附烃-汞气体及氡气测量,CSAMT中低阻异常、烃-汞正异常重叠区域、在构造有利部位是矿体的主要赋矿部位。结合矿区资料,预测在212剖面线（120～140）号间,宽度约700～800m,62剖面线（60～80）号间,宽度约800m 存在两处有利的赋矿异常,为凡口铅锌矿深部找矿预测研究提供切实可行的勘查技术与方法。Fankou Pb-Zn ore deposit is a superscale lead-zinc deposit in northern area of Guangdong with cov-erage soil and unique complex geological environment.Taking Fankou Lead-zinc deposit for an example,it is based on the previous research for application of high precision magnetic method,controlled source audio fre-quency magnetotelluric method,soil electric adsorption,radon,adsorption hydrocarbon-mercury gas meas-urement,and the conductivity and other geophysical and geochemical exploration technology.The compara-tive analysis and research of Fankou lead-zinc ore deposit and its periphery area are carried out to establish ef-fective detection technology integration,optimization method for high precision magnetic method,CSAMT, soil adsorption hydrocarbon-mercury gas and radon measurement,CSAMT low resistance anomaly,hydro-carbon and mercury anomaly overlap region for that the construction site is the main advantage of orebody mine site.Based on these data,ore forecast along No.212 profile （120 ～ 140 dots）are carried out in the width of about 700～800 meters,while ore forecast along No.62 profile （60～80 dots）are also carried out in the width of about 800 meters.There are two favorable ore anomalies to provide practical exploration tech-nology and method for Fankou lead-zinc deposit for deep exploration study on ore prediction in the mine.
