“…In the Tharsis and Rio Tinto deposits of the Iberian Pyrite Belt, pyrite rich samples show Re and Os contents that range from 0.3 to 66 ppb and from 51 to 669 ppt Os (Mathur et al, 1999). Rhenium and Os concentrations for the Wanibuchi Kuroko-type deposit, Japan range from 3.52 to 50.6 ppb and from 20.1 to 92.9 ppt, respectively (Terakado, 2001), whereas the Iimori Besshi-type VMS in Japan shows higher Re and Os concentrations (24.28 to 300.4 ppb Re, 224.9 to 660.5 ppt Os; Nozaki et al, 2010). Higher…”

A C C E P T E D M A N U S C R I P T Chilean IOCGs is the result of different events with metals derived from diverse sources i.e., the magmatic-hydrothermal system and basement/host rocks. A C C E P T E D M A N U S C R I P T ACCEPTED MANUSCRIPTRhenium and Os concentrations for the various studied deposits vary over a wide range of values at the ppb and ppt level, respectively, with many sulfides and magnetite bearing appreciable no common Os. The Re and Os contents in sulfides (pyrite, IOCGs in China and Australia argue for the involvement of a much more radiogenic crustal source possibly related to non-magmatic oxidized saline brines that leached basement rocks. A C C E P T E D M A N U S C R I P T ACCEPTED MANUSCRIPTWe conclude that Andean IOCG (and IOA) deposits in northern Chile were formed mainly by magmatic-hydrothermal processes related to the formation and emplacement of plutonic rocks with moderate contribution from leaching of basement and/or volcanic host rocks. Surface or basin-derived brines as well as sediments appear to play only a minor role in the formation of the Chilean IOCG clan.
