Resumen:
The first d34S values on galena,
sphalerite and various sulfides obtained at INGEIS laboratory, from the
Gonzalito and Vicentito mines, are presented.
The d34S values range from 0 to 4.5?
vs. CDT in Gonzalito and from 1.5? to 7.5? vs. CDT in Vicentito.
The isotopic geothermometer pyrite/galena (py/gn) yield temperatures
around 621K (348°C), higher than
those obtained by other method.
A magmatic hydrothermal origin of mesothermal type is suggested by
isotopic ratios and temperatures obtained.
