摘要

The Hetai gold deposit is the largest gold mine in Western Guangdong and Southeastern Guangxi, which is related to the ductile shear zone. The anomalous belts of K, geo-electrochemical value and volumetric strain increment were used for prospecting in order to find more gold orebodies in the Hetai goldfield. The anomalous belts of K indicate the K alteration took place during mylonitization and hydrothermal alteration. Auriferous veins and mylonitized zones commonly occur within or nearby the anomalous high value belts of K. The anomalous belts of geo-electrochemieal value represent the vertical projection of allopelagic orebodies. The anomalous belts of volumetric strain increment and adjacent areas are possible auriferous mylonitized zone. The anomalous belts of K, geoelectrochemical value and volumetric strain increment correspond well with 9# mylonitized zone. These anomalous belts have been partially or locally proved to be closely related to gold mineralization. These demonstrate that the methods are feasible for prospecting of the deposit.
