摘要

The Dujiadongwu Cu-Mo deposit is located in the Xialvqiao-Xiaoshan Puyang volcanic- structure sag northeast of the Qinghang metallogenic belt, Shoaxing, Zhejiang Province. Its mineralization is intimately related to the Qinghuashan caldera-Longjiaojian volcanic conduit structure. Based on the integrated analysis of geological setting, alteration, geophysical and geochemical characteristics, the regional metallogenic regularity and prospecting indicators are summarized as follows. The areas, including joint space of extension faults in the volcanic conduit, N-W faults, joints and crack belt, contact zone of low and moderate resistivity, zero-value aeromagnetic anomaly district, boundary district of negative and positive aemmagnetic anomalies, high gradient induced polarization district, are the potential places for finding high-concentration ore bodies or veins. Small porphyry intrusions and porphyry deposits likely exist at depth in the Longjiaojian volcanic conduit.
