This paper provides new geochemical, petrographic, and isotopic data over a set of 39 samples representative of all different units present in the quaternary volcanism of Monti Cimini region (Provincia Magmatica Toscana) and Vico volcano (Provincia Magmatica Romana). Monte Cimini volcanics are older in age (around 0.94 Ma) includes trachytic and latitic rocks with isotopic ratios 87Sr/86Sr 0.713413„b14 a 0.715685„b5, and 143Nd/144Nd 0.512053„b3 to 0.5121339„b3. Vico volcano (0.4 Ma) products range between phonolitic and trachyandesitic compositions and shows 87Sr/86Sr values of 0.710923„b5 a 0.711264„b6 and 143Nd/144Nd 0.512092„b3 to 0.512122„b3. All these new data are in good agreement with their former attribution to the aforementioned magmatic provinces.

Abstract
This paper provides new geochemical, petrographic, and isotopic data over a set of 39 samples representative of all different units present in the quaternary volcanism of Monti Cimini region (Provincia Magmatica Toscana) and Vico volcano (Provincia Magmatica Romana). Monte Cimini volcanics are older in age (around 0.94 Ma) includes trachytic and latitic rocks with isotopic ratios 87Sr/86Sr 0.713413„b14 a 0.715685„b5, and 143Nd/144Nd 0.512053„b3 to 0.5121339„b3. Vico volcano (0.4 Ma) products range between phonolitic and trachyandesitic compositions and shows 87Sr/86Sr values of 0.710923„b5 a 0.711264„b6 and 143Nd/144Nd 0.512092„b3 to 0.512122„b3. All these new data are in good agreement with their former attribution to the aforementioned magmatic provinces.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
