We modelled ground deformation at Soufrière Hills Volcano (SHV), using data collected by the Montserrat Volcano Observatory from 2010–2019. We investigate the combined use of Electronic Distance Measuring (EDM) and Global Positioning System (GPS) to ...

Thermomechanical modeling of magmatic systems
Magmatic systems and their volcanoes shape the lives of hundreds of millions of people around the globe. As these transcrustal systems cannot be directly observed, their structure and internal processes can only be inferred by modeling them and comparing the results to surface observations.

Magnetite solubility and iron transport in magmatic-hydrothermal environments [PDF]
-We have examined the effect of pressure on the apparent equilibrium constant, K=, for magnetite solubility (Fe 3 O 4 mt ϩ 6HCl fluid ϩ H 2 fluid ϭ 3FeCl 2 fluid ϩ 4H 2 O fluid ) and the relative iron-carrying capacities of magmatic vapor and brine by ...

Molybdenum isotope fractionation at upper-crustal magmatic-hydrothermal conditions [PDF]
Molybdenum isotopes are an established proxy for paleoredox conditions in low-temperature surface systems. However, the mechanisms behind demonstrated Mo isotope fractionation during igneous and hydrothermal processes at elevated temperatures are still ...

Exploring and Modeling the Magma–Hydrothermal Regime
This special issue comprises 12 papers from authors in 10 countries with new insights on the close coupling between magma as an energy and fluid source with hydrothermal systems as a primary control of magmatic behavior.

Sulfur and chlorine budgets control the ore fertility of arc magmas
Earth’s largest copper deposits form in continental arcs, yet it is not well understood what determines whether a magmatic system generates economic mineralization or not.

Magmatic inclusions in martian meteorites [PDF]
P(論文)Magmatic inclusions in martian meteorites occur mainly within olivine and pyroxene grains. They are a few hundreds of micrometers to less than 10 micrometers across in size and have various mineral assemblages.

The W–Sn Panasqueira ore deposit is a magmatic-hydrothermal system, which includes a high-grade quartz-vein type mineralization and a disseminated greisen-type mineralization occurring in the upper part of the Panasqueira two-mica granite.
