Etna. These magmatic products were investigated within the framework of the 'Progetto di ricerca libera' entitled: 'The Cyclopean Islands (Acitrezza, Catania): a key point to investigate the transition between tholeiitic and alkaline magmatism at Etna'. The project was funded by INGV Dipartimento Vulcani (Prot. N. 3876 del 25/03/2020); Principal Investigator: Rosa Anna Corsaro (INGV, sezione Osservatorio Etneo). Major and trace element concentrations were determined at ALS company (Spain) via ICP-AES (Inductively Coupled Plasma Atomic Emission Spectroscopy) and ICP-MS (Inductively Coupled Plasma Mass Spectrometry), following lithium borate fusion and subsequent acid dissolution. Analytical uncertainty (1sigma) for the reported compositional ranges is 2% for major elements and 10% for trace elements. LEGEND Sample ID: the unique alphanumeric identifier assigned to each sample. Lat (°N) / Long (°E): geographic coordinates of the sample’s collection site in decimal degrees, referenced to the WGS84 datum. Sample description: a summary of the sample’s characteristics, including lithology and structural features. CIPW minerals: theoretical minerals, known as normative minerals, which are calculated from the bulk chemical analysis of a rock. The CIPW Norm calculation (named after its creators Cross, Iddings, Pirsson, and Washington) is based on the original paper: Cross, W. et al (1989) Notes: b.d.l. = below detection limit; b.s.l. = below sea level; wt% = weight percent; ppm = parts per million; LOI = loss on ignition; Ne = nepheline; Hy = hyperstene Mt.
