Radiogenic isotope compositions of eruption products from the 2019 paroxysmal eruptions at Stromboli Volcano

The periodic volcanic activity of Stromboli Volcano, Aeolian Islands, Italy, is interrupted by paroxysmal eruptions on a decadal interval. In 2019, two strong paroxysms on July 3rd and August 28th, ended a more than a decade long period of regular strombolian activity. During normal strombolian activity the volcano erupts highly porphyritic scoria and lava (HP) with a shoshonitic basalt composition. In paroxysmal eruptions the HP material is mingled with low porphyritic (LP) pumices. This dataset includes the first radiogenic isotope data on the bulk compositions of the LP and HP components erupted on July 3rd 2019, and a HP sample from the lava flow that followed the paroxysm, and a LP sample from the paroxysm on August 28th 2019. The analyzed radiogenic isotope ratios include Sr, Nd, Hf, and Pb. This dataset further includes in-situ EPMA and LA-ICP_MS measurements of major and trace elements in the glass, olivine, plagioclase and clinopyroxene phases.
