Constraints on the sulfur subduction cycle in Central America from sulfur isotope compositions of volcanic gases
(European Association of Geochemistry, 2022-01-20)
The sulfur cycle at convergent margins remains poorly constrained yet is fundamentally important for understanding the redox state of Earth's reservoirs and the formation of ore deposits. In this study we investigate the ...
Poás volcano: Geophysical-Geochemical signatures and dynamics of its magmatic-hydrothermal system
(International Association of Volcanology and Chemistry of the Earth's Interior, 2014-09)
Poás volcanic complex hosts a hyper-acid lake where geochemical signatures are related to two major controlling processes: (a) The level of inux and dissolution-hydrolysis of magmatic volatiles in a sub-surface hydrothermal ...
Magmatic volatiles in ash leachates and environmental impact assessment of the 29-30 October 2014 phreatic eruptions of Turrialba Volcano, Costa Rica

Using the sulfide replacement petrology in lunar breccia 67915 to construct a thermodynamic model of S-bearing fluid in the lunar crust
(Elsevier, 2015-12-15)
In this work, we investigate the compositions and origin of metasomatic fluids responsible for the formation of sulfide replacement textures in Mg-Suite lithologies of lunar samples 67915-149 and 67915-150. We have constructed ...
