A correct description and quantification of the geochemical behaviour of REE+ Y (rare earth
elements and Y) and HFSE (high field strength elements) is a key requirement for modeling …

Plagioclase is the most common phenocryst in all Etnean magmatic suites (~ 50% in
volume), as well as in most lavas erupted worldwide. Its stability field is strongly dependent …

We have refined the clinopyroxene-based hygrometer published by for a better quantitative
understanding of the role of H2O in the differentiation of Etnean magmas. The original …

Petrological investigations of active volcanoes are often supported by mass balance,
thermodynamic calculations and/or experiments performed at key conditions. Conversely …

Mafic enclaves preserve a record of deep differentiation of primitive magmas in arc settings.
We analyze the petrology and geochemistry of mafic enclaves from Shiveluch volcano in the …

Basaltic magmas can transport and release large amounts of volatiles into the atmosphere,
especially in subduction zones, where slab-derived fluids enrich the mantle wedge …

A 4-year geochemical survey of some fumaroles at the Voragine summit crater of Mt Etna
was performed in combination with synchronous monitoring of peripheral gas emissions at …

Coupled textural and in situ geochemical studies of clinopyroxene (cpx) phenocrysts, from
both historical and recent eruptions of Mt. Etna volcano, provide a means to investigate the …

Seven rock samples were systematically collected from innermost to the outermost portion of
a dike outcropping at Mt. Etna volcano. Results show that, from dike core-to-rim, plagioclase …

The solidified surface of a lava flow reflects the viscosity of its molten fraction and the crystal
content during flow; crystal-poor basaltic lavas produce pahoehoe fields, whereas crystal …
