Mineralogical, petrographic and fluid inclusions studies
Information on the characteristics of the reservoir rocks and on the
physical-chemical evolution of the fluid migrating in geothermal
systems
Past fluid migration at Larderello
“early-stage”
“late-stage”
Contact-metamorphism
Hydrothermal alteration
Evidence of fluid evolution from fluid inclusions
“contact-metamorphic” and “magmatic derived” fluids
“hydrothermal” fluids
