| 摘 要： | A symplectite of pyrite and magnetite in the massive sulphide ore of the Mashan mine,Anhui Province,is interpreted to have been formed by their replacing earlier pyrrhotite.The compositions of pyrrhotite,pyrite and magnetite related to this texture are given by electron microprobe analysis.Such a texture is likely to be formed when the ore-forming system reaches the three-phase point of pyrrhotite,pyrite and magnetite from the pyrrhotite stability field.The very small probability for the system to reach this point could be used to account for the rare occurrence of such symplectite in natural ores.

| Abstract: | A symplectite of pyrite and magnetite in the massive sulphide ore of the Mashan mine, Anhui Province, is interpreted to have
been formed by their replacing earlier pyrrhotite. The compositions of pyrrhotite, pyrite and magnetite related to this texture
are given by electron microprobe analysis. Such a texture is likely to be formed when the ore-forming system reaches the three-phase
point of pyrrhotite, pyrite and magnetite from the pyrrhotite stability field. The very small probability for the system to
reach this point could be used to account for the rare occurrence of such sympletite in natural ores. |
