Sulfur: A Unique Player for Redox Evolution, Volatile Degassing, and Metal Transport in Magmatic, Volcanic, and Hydrothermal Systems Posters

Session ID#: 46305

Session Description:
Sulfur is a remarkable element that plays a major role in a range of volcanic, magmatic, and hydrothermal processes. The presence of sulfur affects the partitioning of various elements between mineral, melt, and volatile phases. The polyvalent and multi-speciation nature of sulfur in these phases makes it a unique proxy for redox processes, but adds significant challenges to sulfur-related research.

Sulfur contents and species in volcanic gasses provide critical information on volcanic activity assessment. In this regard, our understanding of the temporal evolution of volcanic gas signatures is largely dependent on experimental and thermodynamic modeling approaches, combined with field observations.

In this session we aim to facilitate dialogues between the computational, experimental and field-based volcanology, petrology, and economic geology communities, to better understand the role and behavior of sulfur and associated elements in magmatic, volcanic, and hydrothermal systems. Contributions based on interdisciplinary observations and novel analytical techniques are encouraged.
