“…This depth range is in line with both estimates of major storage regions within the Ischia magmatic plumbing system based on geophysical modeling Paoletti et al 2009;, and recent MI data (Sbrana et al 2009;Moretti et al 2013). It also corresponds to the depths of magmas feeding the adjacent Campi Flegrei caldera (e.g., Mangiacapra et al 2008;Arienzo et al 2010, and references therein).…”

The deep-sourced latitic to trachytic magmas stalled at shallow depths (4-6 km depth), differentiated to phonolite through crystal fractionation and assimilation of a feldspar-rich mush, or ascended directly to the surface and erupted.

“…The boundaries of this caldera were defined by the authors based on the distribution of structures belonging to the older than 55 ka BP volcanic complex. The analysis of recently acquired high-resolution aeromagnetic data (Paoletti et al, 2009) showed a correspondence between the ancient rocks located along the coastline and the horizontal gradient maxima of the magnetic field (Fig. 7).…”

“…These magma-derived volatiles are possibly sourced by the degassing of a 1000°C trachytic magma at around a 2 km depth [42]. The presence of high temperatures below the island is also confirmed by the lack of a clear magnetic signature over the central sector of Ischia [31,32]. This is possibly due to the hydrothermal alteration phenomena of the igneous materials and/or the presence of partially molten areas inside the island's magmatic basement.…”

h i g h l i g h t sA method to evaluate the potential for electric power production at geothermal sites. It evaluates geofluid's flow rate, pressure, temperature and non-condensable gases. It defines the best plant option and finally returns the actual available power. a r t i c l e i n f o b s t r a c tThe paper proposes a method to evaluate the potential for electric power production at any site of possible geothermal interest. Accounting for geological data of the reservoirs, the method allows the computation of the available electrical power of the investigated site. Electrical energy production from geothermal sources is realized through different techniques, such as single flash and double flash, dry steam, and binary ORC plants. The technique chosen to be the most productive is determined by analyzing a specific range of geofluid properties, mainly temperature and pressure. Moreover, each plant typology has a global efficiency that may be correlated to geofluid enthalpy by empiric relations available in literature. The proposed evaluation method brings together all these correlations, yielding the power availability from a geosource, once its temperature and pressure are known. The method takes as input the geofluid available flow rate, its pressure, temperature and non-condensable gas content. It defines the best plant option from these parameters, calculates its global efficiency and finally returns the actual available power. For sites of geothermic interest, such as the volcanic island of Ischia in Southern Italy, the results of the application of this new method clearly highlight the most suitable zones for power plants installations.
