Dear colleagues,
I would like to draw your attention on the following session at the AGU Fall meeting:
Sulfur (Bio)geodynamic Cycles on Earth and Terrestrial Planets (session #13340)
Sulfur is exchanged between the Earth?s surface and the mantle via subduction zones, magmatism, volcanic degassing, hydrothermalism, biological sulfate reductions and continental weathering. It also plays important roles in geological processes on other terrestrial planets. Yet, its transport and storage from the oceans and continents into the deep Earth, and secular changes in the mode of S-exchange between different igneous and surficial reservoirs remain discussed. Sulfur behavior is also related to its multiple valence states, implying complex interplays with redox state, and affecting sulfur partitioning between minerals, melts and fluids. This session seeks contributions from geochemistry, petrology, laboratory experiments, and field geology addressing the fate of sulfur in various geodynamic settings on terrestrial planets. We will also address the role of sulfur in the redox evolution and biochemical cycles, volcanic degassing, the distribution of chalcophile elements and ore-deposit formation, and coupling with other key volatiles such as carbon and halogens.
