Aspects of Norilsk Cu-Ni ore crystallization according to the data of the experimental study of Cu-Fe-S system
A study of the Cu-Fe-S melts crystallization products synthesized at low (0,13 Pa) and at high (5 GPa) pressure has been conducted. The study has shown that in contrast to the crystallization products of the Cu-Fe-S melts synthesized at pressure 0,13 Pa where the chalcopyrite solid solution (Cu,Fe)S...

| description | A study of the Cu-Fe-S melts crystallization products synthesized at low (0,13 Pa) and at high (5 GPa) pressure has been conducted. The study has shown that in contrast to the crystallization products of the Cu-Fe-S melts synthesized at pressure 0,13 Pa where the chalcopyrite solid solution (Cu,Fe)S11_x (5 > х > 0 аТ%) was crystalized, in crystallization of the Norilsk Cu-Ni-Fe-S melt, pentlandite (Ni,Fe)9S8 is crystalized simultaneously with chalcopyrite CuFeS2, cubanite CuFe2S3 and pyrhotite Fe1_xS. The results correspond to the data about composition of Cu-Fe-S system (bornite Cu5FeS4 + new fase Fe4CuS5) at 1100 °C and 5 GPa and the published data about initial melt compositions for Cu-Ni-Fe sulphide associations from the inclusions in the minerals of kimberlite tubes. The obtained results indicate the formation of Norilsk Cu-Ni deposits at high pressure. |
