Il database contiene le composizioni delle rocce totali (elementi maggiori ed in tracce) di lave e piroclastiti campionati all'Etna nel 2021 durante l’attività di monitoraggio petrologico dell’INGV-OE. The preparation and analyses of the sample have been performed at INGV laboratories. After archiving, the samples were reduced to powder, the LOI was determined and finally they were melted (Miraglia, 2012 ). The beads were analyzed for X-ray fluorescence. The bulk rock compositions have been analyzed at INGV-OE with the Rigaku Primus II XRF. The accuracy of our measurements has been checked through replicate analyses of the international standard (Jarosewich et al., 1980). The precision, expressed as relative standard deviation, is less than 1% for SiO2, Al2O3, FeO, MgO and CaO and less than 3% for TiO2, MnO, Na2O, K2O and P2O5 (Miraglia, 2013), <5% for Ba, Ce, La, Nb, Nd, Rb, Sm, Sr, V, Y, Yb, Zn e Zr, e <10% for Cr, Ni e Th (Miraglia, 2017). Each measure is the average of 3 analyses. Dataset legend Sample Label: name identificative of the sample, Date of sample's eruption: (DD/MM/YYYY); Eruptive vent/Fissure: the Acronyms used for Etna summit craters are VOR= Voragine Crater, BN=Bocca Nuova Crater, NEC=North-East Crater, SEC=South-East Crater, NSEC=New South-East Crater; Activity type: description of the eruption activity (eg: effusive, spattering, Strombolian explosions, paroxysm, ash emission, other) Sample type/size: lava, bomb or lapilli).
