Halogen group elements, particularly fluorine and chlorine, are useful in tracing range of fluid that may be present during prograde metamorphisms associate to subduction. For example, recent result from LMV reported contrasting findings. (1) High pressure hydrothermal experiment determined... read more

Sulfide minerals are amongst the main constituents of meteorites, together with silicates and metal. The most abundant sulfide type is troilite, FeS. However, in meteorites condensed or equilibrated at very low oxygen fugacities a collection of more varied sulfides such as MgS , MnS... read more

Changes of topography with time at active volcanoes are the result of endogenic processes (ground deformation related to magmatic intrusions, hydrothermal activity) and exogenic processes (eruptive products: dome growth, pyroclastic flows, lava flows, etc.). Different methods allow... read more

Understanding how lava flowing in a channel cools, crystallizes and vesiculates with distance from the vent is imperative if we are to track down flow changes in the flow rheology (viscosity and yield strength). These factors, in turn, will control the ability of the lava to move, and... read more

Cerium is a rare earth element (REE). REE cations are all trivalent except two of them that present two different oxidation states. Amongst them cerium may be present under both the Ce3+ and Ce4+ forms. The coexistence of these two cations has important implications... read more

Pyroclastic flows are mixtures of gas and particles generated by explosive volcanic eruptions and that can propagate at high velocity over distances of several kilometres. Field studies and recent experimental works suggest that the deposit of individual flows of small volume form incrementally,... read more
