Yaoshangkeng area in eastern Yuhuashan volcanic basin lies in the northeastern part of the Qinzhou-Hangzhou metallogenic belt. The complex tectonic setting of the study area is favorable for mineralization. According to the result of mathematical analysis and single element anomalies, Cu has a close affinity with Mo, so do Pb and Zn. The copper anomaly area and molybdenum anomaly area, characterized by large size and high intensity, are distributed on both sides of the contact zones between magmatic rocks and metamorphic rocks, show good consistency with each other, and may be related to the medium-high temperature mineralized hydrothermal filling metasomatism on the lithologic interfaces. Four areas were selected as targets for further exploration, and anomaly verification for target area Ⅱ shows that the strongest anomalies usually appear around the fractured quartz veins caused by extension fractures. In order to determine the major factors (NE-trending faults or different lithological contact zones) that are responsible for element anomalies, the authors suggest the performance of relevant anomaly verification in the other three target areas.
