GNGTS 2021 - Atti del 39° Convegno Nazionale

119 GNGTS 2021 S essione 1.2 Fig.1 - Selected major elements plotted against SiO 2 (wt.%) measured in MIs found in products erupted from 2013-2018 Mt. Etna activity; grey symbols represent Type 1 MIs, whereas type 2 MIs are red; squares represent the February 19, 2013 eruption at NSEC (NSEC 2013); circles represent the paroxysmof December 3, 2015 at VOR (VOR 2015); triangles represent the flank eruption occurred on December 24-27, 2018 (DEC 2018); 2001-2017 whole-rock compositions (grey asterisks), FS whole-rock and MI compositions erupted during the 3930 B.P. (dark grey squares and light grey diamonds) are reported for comparison. The dark grey area represents the rhyolite-MELTS simulation starting from the FS composition.
