| 内容記述 | The Ok Tedi ore deposit is an epicontinental porphyry copper system in Papua New Guinea. The behavior of halogen elements in the mineralization was considered based on the chemical compositions of biotite and apatite. The Si and Mg/(Mg+Fe) of biotite increased, and Ti decreased with advancing hydrothermal activity. The change of chemical composition of biotite suggested a decrease of temperature and/or an increase of oxygen fugacity. Biotite and apatite were characterized by an enrichment of F, as well as an enrichment of other incompatible elements (apatite), compared to those in the island arc regions in Papua New Guinea. The magmatism in this field might originate in the continental crust, or might be strongly contaminated with crustal materials. The fHF/fH_2O ratios on isothermal projection suggested further concentration of F in the residual magma during solidification of originally F-rich magma. The fHCl/fH_2O ratio in magma in the Ok Tedi mining district was similar to those in island arc region. The ratio has a tendency not to concentrate in the ordinary acidic magmatism of the continental region, that is, the Ok Tedi mining district should be regarded as an abnormal Cl enriched field. The fHCl/fH_2O ratio on isothermal projection has increased at the veining stages. The effective transportation mechanism of base metals in the Ok Tedi mining district was suggested by HOLLAND's simulation (1972). |
