Abstract
  • Pantelleria,? a? small? volcanic? island? located? in? the? Sicily? channel,? contains? a? water? dominated? geothermal? field? in? its? southern? part.? The? reservoir,? characterized? by? temperature?of?about?250?°C,?was?tapped?by?a?990?m?deep?well,?which?highlighted?the? existence? of? deep? fluids? of? marine? origin? significantly? depleted? in? Ca? and? Mg? and? enriched?in?Si?and?K?due?to?the?interaction?with?trachytic?rocks?hosting?the?geothermal? reservoir.?Significant?temperature?inversions?with?depth?are?observed?between?20?and? 100? m? b.s.l? in? five? shallow? exploratory? wells? drilled? throughout? the? island.? These? inversions?are?due?to?hot?waters?which,?with?temperature?up?to?110?°C?and?represented? by?variable?mixtures?of?meteoric?recharge?and?sea?water,?flow?over?a?denser?and?colder? sea? water? from? the? inner? to? the? external? parts? of? the? island.? The? hydrogeological? conceptual?model?foresees?a?groundwater?circulation?characterized?by?convective?flows? whose?main?engine?is?represented?by?the?geothermal?system.? (literal)
