Over the last several hundred years, Stromboli has been characterized by steady-state Strombolian activity. The volcanic products are dominated by degassed and highly porphyritic (HP-magma) black scoria bombs, lapilli and lava flows of basaltic shoshonitic composition. Periodically (about one to three events per year), more energetic explosive eruptions also eject light coloured volatile-rich p...

Integrated spectroscopic analyses and synchrotron X-ray microdiffraction investigations provide insights into the long-term reactivity of volcanic aggregate components calcium-aluminum-silicate-hydrate (C-A-S-H) binder in mortar samples from robust concrete sepulchral corridor Tomb Caecilia Metella, 1st C BCE, Rome. The results innovative micrometer-scale analytical maps indicate that Pozzolane...

This study reports the first measurements of sulphur and boron isotopic compositions in olivine-hosted melt inclusions (MI) from basaltic lava scoria deposits 1941 Tolbachik eruption, Kamchatka, Russia. The primary aim present is to constrain origin relation silicate-sulphide immiscibility that occurred mafic magmas. Melt fall into two compositionally distinct groups based on their S- B-isotope...
