摘要

Despite 130 years of very detailed study,many aspects of the generation of the 1850 Ma Sudbury Igneous Complex (SIC) and associated Ni-Cu-PGE ores are not clear.Recent developments include suggestions of 1) oblique impact,explaining how a ≥200 km diameter impact structure could have a melt sheet with a dominantly upper-middle crustal composition,2) larger than appreciated post-impact contributions from locally thermomechanically eroded footwall rocks and mineralization,explaining large heterogeneities in S and Pb isotopes between different ore deposits and parts of the melt sheet,3) reactions between sulfide melts and footwall rocks,providing a mechanism to cross the thermal divide in the Fe-Ni-Cu-S system and generate bornite-millerite-rich ores,and 4) more complicated deformation histories involving multi-directional thrusting of ore bodies during buckling and rotation of the southern contact of the SIC.
