Metallogenic Series and Model of the Zijinshan Mining Field

The Zijinshan Mining Field, which is dominated by the Zijin copper-gold deposit, is the first high- sulfide epithermal deposit discovered in China. The porphyry copper (molydenum) deposit,the meso-low-temperature hydrothermal copper deposit,the lower- sulfide epithermal silver(gold-copper) deposit,the volcanic uranium deposit and the high-temperature hydrothermal tungsten(tin) geochemistry abnormity were discovered in the depth and vicinity of the deposit. From late Jurassic,it had gone through multiphase-tectonic movement, magmation and hydrothermal alteration, which had resulted in multiphase-mineralization. This paper points out that the mineralization system of the Zijinshan Mining Field is characterized by tectonic structure,body within body,altered alteration,mineralized mineralization, and by a vertical zonation of minerlization: U、Ag→Au→Au、Cu→Cu→Cu、Mo→W、Sn from top to bottom, and a multi-storey metallogenic model. The different deposit types show laterally-distributed patterns spatially, forming a unique Zijin-typed metallogenic series and minerization. Compared with other deposits, it is likely that the porphyry copper (molydenum) deposit and the high-temperature hydrothermal tungsten(tin) may exist at the depth of the porphyry copper (molydenum) deposit and its vicinity respectively. The research shows that there will be a new exploration field in the mining field and provides a scientific base for further exploration.
