Skarn development in calcareous-pelitic succession affected by thermal metamorphism and fluid flow at Acquarilli beach (Elba Island, Italy)

Skarn deposits represent one of the most significant ore types occurring throughout the world (Meinert et al. 2005 and references therein). Their importance derives from the variety of elements that could be enriched during their formation (Meinert et al. 2005 and references therein; Zharikov et al. 2007). Skarn mineralization is formed as a consequence of the emplacement of magmatic bodies at relatively shallow depth which trigger metamorphic and metasomatic reaction involving both intrusive host rocks in the presence of magmatic- and/or metamorphic-derived fluid. In the Elba Island (Tuscan Archipelago, Italy), two magmatic bodies intruded into the upper crust (c. 6 km depth): the Monte Capanne (western side) and the Porto Azzurro (eastern side) monzogranite plutons, dated at c. 7.2 and 6.5 Ma, respectively (Gagnevin et al. 2011). Their emplacement occurred during the extensional tectonics that, since early Miocene, affected the inner Northern Apennines giving rise to the northern...
