Il datadase include i rapporti isotopici di 87Sr/86Sr e 143Nd/144Nd, misurati su rocce totali di lave e piroclastiti campionati all'Etna nel 2013-2017 durante l’attività di monitoraggio dell’INGV-OE. The chemical treatment of the samples was carried out in the clean laboratory of the INGV-OV. Before chemical dissolution whole rock have been dissolved with high-purity HF–HNO3–HCl mixtures. Sr and Nd have been separated from the matrix through conventional ion-exchange chromatographic procedures, described in detail in Arienzo et al. (2013, 2014). Isotopic ratios have been measured by thermal ionization mass spectrometry (TIMS), using a Triton Plus® (Thermo Scientific) solid-source multicollector mass spectrometer in static mode. The blank was negligible considering the average Sr content of the samples; no determinations for Nd blanks was performed. Measured 87Sr/86Sr and 143Nd/144Nd ratios have been normalized for within-run isotopic fractionation to 88Sr/86Sr =8.375209 and 146Nd/144Nd =0.7219 respectively, using an exponential law for correction. During collection of isotopic data, replicate analyses of NIST-SRM 987 and JNdi-1 international reference standards have been performed to check for external reproducibility. During the period of analysis, the mean measured value (Goldstein et al., 2003) of 87Sr/86Sr 265 Sr for NIST-SRM 987 was 0.710242±0.000013 (2σ, where σ is the standard deviation of the values; n=48); that of 143Nd/144Nd for JNdi-1 was 0.512105±0.000007 (2σ, n=20) at Osservatorio Vesuviano. Sr and Nd isotope ratios of the samples have been normalized to the recommended values of NIST-SRM 987 and JNdi-1 (87Sr/86Sr 269 =0.710248; 143Nd/144Nd =0.512107; Zhang and Hu, 2020), respectively.
