dc.description.abstractThe Salamon gold prospect constitutes an example o f carbonate-hosted gold deposit formed during the last events of the Hercynian orogeny. It is formed by a complex paragenetic sequence o f Au-As-Sb-Hg-Cu-NI-Co-Pb-Zn-U minerals in jasperoid and quartz-dolomite host rock. Au correlated positively with As at single crystal scale in pyrite and arsenopyrite, of fluid inclusion study and arsenopyrite geothermometry show temperatures in the range 140-280°C at 350-400 bars. Stable isotope data suggest reduction of sulfur from marine evaporites and buffer of carbon in the fluid by the host carbonates.The age of the deposit is 269 ± 5 m. y., U-Pb determination on uranite grains gires and which is consistent with on uranite age from Villamarin and with age determinations of intrusive rocks spatially associated to several ore deposits in the areaen_US
