The Island of Pantelleria is a composite volcano located in the Sicily Channel. The composition of the rocks erupted, consistent with a continental extensional setting, range from pantellerite to trachyte with minor outcrops of alkalic basalts. Relative to a plinian event dated about 45ka, a large amount of ash-flow tuffs and pyroclastic fall related deposits has been erupted. These deposits, known as Green Tuff, cover nowadays about 50% of the island'surface and are characterized by severe rheomorphic deformation. The analysis of these rheomorphic structures shows that they are referable to both primary and secondary flow mechanisms.

Abstract
The Island of Pantelleria is a composite volcano located in the Sicily Channel. The composition of the rocks erupted, consistent with a continental extensional setting, range from pantellerite to trachyte with minor outcrops of alkalic basalts. Relative to a plinian event dated about 45ka, a large amount of ash-flow tuffs and pyroclastic fall related deposits has been erupted. These deposits, known as Green Tuff, cover nowadays about 50% of the island'surface and are characterized by severe rheomorphic deformation. The analysis of these rheomorphic structures shows that they are referable to both primary and secondary flow mechanisms.File in questo prodotto:
