An interpretative view of open-vent volcanoes
Open-vent volcanoes are special systems where the dynamics of sustained magmatic processes can be thoroughly investigated and where new monitoring tools can be tested and applied. However, various aspects rema...

Footprints and conditions of multistep alkali enrichment in basaltic melts at Piton de la Fournaise (La Réunion Island, Indian Ocean)
Deciphering magma evolution below ocean basaltic volcanoes is all the more challenging because magma mixing is a common process tending to modify the pristine geochemical diversity during magma ascent. On the ...

Boron in the Bolivian tin belt
Tourmaline alteration and high boron contents are typical features of the magmatic-hydrothermal systems of the Bolivian tin province. The average boron content in melt inclusions of quartz phenocrysts from ti...

Mafic magma batches at Vesuvius: a glass inclusion approach to the modalities of feeding stratovolcanoes
Glass inclusions in olivine and diopside phenocrysts from pyroclasts of various eruptions of Vesuvius are representative of the magmas that supplied the volcano in the last 4–5000 years. During this interval t...

Sulphur output and magma degassing budget of Stromboli volcano
STROMBOLI volcano in the Aeolian islands has been erupting continuously for more than 2,000 years1, and probably as many as 5,000, following a major flank collapse2,3. Here we describe air-borne measurements of t...

Optimation of fluorine detection for biological and geological applications with a nuclear microprobe
A review of the nuclear reactions used to determine fluorine is presented. In order to optimize the detection of fluorine in biological or in geological samples, a comparison of the performances obtained with ...

Geochemical constraints on source region of Cretaceous/Tertiary impact glasses
THE 50-cm-thick Cretaceous/Tertiary boundary layer at Beloc in Haiti contains spherules of silicic black glass, 1–8 mm in diameter, which have been attributed to impact fusion of continental crust1. Calcic yellow...

Melt inclusion investigation of the volatile behaviour in historic alkali basaltic magmas of Etna
Crystallization paths of basaltic (1763 eruption) and hawaiitic (1865 and 1329 eruptions) scoria from Etna were deduced from mineralogy and melt inclusion chemistry. The volatile behaviour was investigated thr...

The somma-vesuvius magma chamber: a petrological and volcanological approach
The volcanic history of Somma-Vesuvius indicates that salic products compatible with an origin by fractionation within a shallow magma chamber have been repeatedly erupted («Plinian» pumice deposits). The last...
