Constraints on the ore fluids in the Sando Alcalde Ausingle bondAg epithermal deposit, southwestern Peru: fluid inclusions and stable isotope data ----- Contraintes sur les fluides minéralisateurs du gisement Ausingle bondAg de Sando Alcalde, Sud-Ouest du Pérou : données des inclusions fluides et des isotopes stables

The Sando Alcalde ore deposit (southwestern Peru) has been studied in order to characterize the physicochemical parameters of the ore fluids and to determine the fluid process (mixing or boiling) which involves the precious metal mineralization. Mineralogy, δ18Oquartz isotopic values and fluid inclusion data give arguments in favour of a boiling phenomenon. This conclusion corroborates fluid inclusion studies previously performed in this area on the low-sulphidation epithermal deposits of Arcata, Orcopampa and Apacheta, where boiling has been described as the main factor for ore deposition
