    Abstract
  • Several mafic-ultramafic intrusions hosting economic Ni-Cu-(PGE) sulfide deposits and sub-economic sulfide mineralization occur in the central zone of the Emeishan large igneous province (LIP). These magmatic sulfide deposits can be divided into the Ni-Cu type (e.g. Limahe and Qingshuihe), Ni-Cu-PGE type (e.g. Qingkuangshan and Huangcaoping) and PGE type (e.g. Jinbaoshan and Yanghewu), according to the variations in the content of platinum-group elements (PGE). Electron microprobe analyses of olivine show that almost all olivine crystals are chrysolite (Fo76.8-Fo89.6), with an exception of some grains from the Qingkuangshan intrusion which are forsterite (Fo90.1-Fo93.1). The compositions of olivine are distinct between intrusions containing different types of sulfides. For the Ni-Cu sulfide-bearing intrusions, the Fo and Ni contents of olivine range from 77 to 87 and from 976×10-6 to 2 176×10-6, respectively. Olivine crystals in the Ni-Cu-PGE sulfide-bearing intrusions have Fo numbers varying from 80 to 86 and (1 024-2 543)×10-6 Ni. The PGE sulfide-bearing intrusions contain olivine crystals with Fo numbers ranging from 78 to 84 and Ni contents of 776×10-6 to 1 755×10-6. The olivine from the Qingkuangshan intrusion, which contains economic Ni-Cu-PGE sulfides, is distinct from others by its high Fo numbers (up to 93.1) and CaO content (0.24%-1.14%) and extremely low Ni (266×10-6). The Ni concentrations and Mg# of parental magma have been estimated by using the compositions of most Fo-rich olivine crystals and the results show a high-MgO picritic-basaltic magma. Modeling of olivine fractional crystallization and sulfide segregation show that the parental magma for the Ni-Cu type mineralized intrusions has experienced the most extensive sulfide segregation (~0.1%). For the Ni-Cu-PGE type intrusions, it is ~0.06%, and for the PGE type intrusions it is ~0.02%. Re-equilibration of the early formed olivine crystals with the trapped liquid can account for the variations of olivine compositions.
