Abstract:
The Zijinshan Mining Field, which is dominated by the Zijin copper-gold deposit, is the first highsulfide epithermal deposit discovered in China. The porphyry copper (molydenum) deposit,the meso-lowtemperature 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 multiphasemineralization. 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.wSn" 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.
