The effect of iron content and iron nanolites on Raman spectra of hydrous geologically-
relevant glasses is presented. Current procedures to estimate the water content using …

Porcelain stoneware traditionally contains low Fe 2 O 3 (< 1 wt.%), limiting research on iron's
effects beyond coloration to date. However, recent changes in the supply chain induced a …

Iron and water content substantially affect the physical properties of natural silicate melts
and may, therefore, influence magmatic and volcanic processes such as crystallization …

The iron coordination, its oxidation state (Fe 2+/Fe tot.), and alkali ratio [Na/(Na+ K)] greatly
influence the structure and thus the viscosity of volcanic melts, which is known to play a key …

The state and properties of magma are crucial controls on the eruptive behaviour of volcanic
systems. Nowhere is the importance of the link between the state and properties more …

In this work, glass-ceramics in the xBeO–20Fe 2 O 3–(80-x) TeO 2 system with x= 0–25
mol% were synthesized by the traditional melt quenching route and studied by inductively …

Iron oxidation state and environment in magmas affect their phase diagram and their
properties, including viscosity and density, which determine magma mobility and eruptive …

In iron-containing silicate melts such as gasification slags and geological slags, iron can
play a different role in the melt properties because of its varying valence states. In this paper …

Résumé The eruptive history of Pantelleria has been marked by the eruption of nine
peralkaline ignimbrites, with inter-ignimbrite episodes from small, local volcanic centres …

Re-use of neglected and frequently landfilled wastes, including earthquake-generated
rubble, can reduce the environmental impact of such waste materials, avoiding georesource …
