This work focuses on a rigorous analysis of the physical–chemical, compositional and
textural relationships of amphibole stability and the development of new thermobarometric …

Almost all magmas contain sulfide-or sulfate-bearing phases. In most natural samples the
sulfur-bearing phase is a sulfide, which typically is pyrrhotite (Fe1− xS) or pyrite (FeS2) …

Phenocryst zoning patterns are used to identify open-system magmatic processes in the
products of the 2001 eruption of Shiveluch Volcano, Kamchatka. The lavas and pumices …

Explosive volcanic eruptions are driven by exsolution of H2O-rich vapour from silicic
magma. Eruption dynamics involve a complex interplay between nucleation and growth of …

A method is described for estimating the activity of titania (TiO 2) in a magmatic liquid from
the compositions of coexisting cubic oxide (spinel) and rhombohedral oxide (ilmenite) …

Many lava dome building eruptions show periodic to complex non-periodic pulsatory activity.
Typical time-scales associated with this activity range from hours to decades. Previous …

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 …

Using a compilation of melt compositions, meltwater contents, temperatures, and phenocryst
contents, the preeruptive viscosities under magma reservoir conditions are calculated for 83 …

Abstract The~ 16-ka-long record of explosive eruptions from Shiveluch volcano (Kamchatka,
NW Pacific) is refined using geochemical fingerprinting of tephra and radiocarbon ages …

During an effusive–extrusive eruption, the capability of an active lava body (flow or dome) to
radiate thermal energy depends on how the lava discharge rate is accommodated by the …
