Duchi V., Minissale A., Manganelli M. Chemical composition of natural deep and shallow hydrothermal fluids in the Larderello geothermal field. In: Journal of Volcanology and Geothermal Research, vol. 49 (3-4) pp. 313 - 328. Elsevier, 1992.
The chemical composition of the shallow and deep natural hydrothermal fluids discharged from the Larderello geothermal field (central Italy) is related to the main hydrological and lithological characteristics of the rock formations present in the reservoir as well as to the chemico-physical changes that have occurred in the geothermal field since exploitation for the production of electric energy started. The chemico-physical modifications caused by exploitation reveal that the fluids feeding the field may be partly derived from meteoric waters directly infiltrating through formations once considered cap rocks. Finally, the persistence of some of the field production parameters and the permanence of some natural manifestations seems to suggest that the reservoir is still at a stage where its resources are not yet fully assessed.
