“…However, microbiostratigraphic and tectonic studies (Isozaki et al, 1990;Isozaki and Maruyama, 1991) suggested that the major deposits associated with chert and basalt are of oceanic origin and are allochthonous to the continental margin environment. The Besshi-type cupriferous sulfide deposit is now known to have been formed by basaltic volcanism at a midoceanic ridge (Sato and Kase, 1996;Okamoto et al, 2000;Isozaki and Nakayama, 2003;Terabayashi et al, 2005;Nozaki et al, 2006Nozaki et al, , 2010. In a recent study, we proposed a new concept on the genesis of the bedded manganese deposits (Nakagawa et al, 2009).…”

“…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.

“…In contrast, supported by the fossil Makimoto and Takeuchi (1992)). and geochronological data for Mikabu rocks in different regions (e.g., Isozaki and Itaya, 1990;Ozawa et al, 1997a,b;Nozaki et al, 2010), the Mikabu unit, including that occurs at the Kanto Mountains, is still considered to be part of the Sanbagawa metamorphic belt. Based on the available data, it is now concluded that the protoliths of the Sanbagawa metamorphic belt were formed as an accretionary complex in a trench at ca.…”
