A two-component mantle source feeding Mt. Etna magmatism: Insights from the geochemistry of primitive magmas
The major elements, trace elements and Sr and Nd isotopes of selected Etnean primitive
rocks (< 15 ky BP) were studied in order to characterize their mantle source. The noble-gas …

New mafic magma refilling a quiescent volcano: Evidence from He‐Ne‐Ar isotopes during the 2011–2012 unrest at Santorini, Greece
Abstract In 2011–2012, Santorini was characterized by seismic‐geodetic‐geochemical
unrest, which was unprecedented since the most‐recent eruption occurred in 1950 and led …

The low primordial heavy noble gas and 244Pu-derived Xe contents of Earth's convecting mantle
Clues to unraveling the origin and history of terrestrial volatiles lie in the noble gas record of
Earth's mantle. However, the low abundance of heavy noble gases (Ar-Kr-Xe) in mantle …

Cycles and trends in the recent eruptive behaviour of Mount Etna (Italy)
B Behncke, M Neri - Canadian Journal of Earth Sciences, 2003 - pubs.geoscienceworld.org
Mount Etna is among the few volcanoes on Earth that erupt nearly continuously, but its
activity (in terms of output rate and flank eruption frequency) undergoes significant …
