Fluid sources and evolution in the As (±Sb) epithermal Matra deposit (Alpine Corsica, France): Constraints from fluid inclusions, gas compositions, and stable isotopes (C–O)

Key Points

• Fluid inclusions indicate diverse fluid sources and evolutionary stages in the Matra deposit.
• Key evidence suggests that both gas compositions and stable isotopes reveal the influence of magmatic sources on mineralization.
• Analytical methods centered on fluid inclusions and isotopic analysis highlight the complexity of the hydrothermal system.
• These findings emphasize the importance of understanding fluid origins for future mineral exploration in similar regions.
