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.
