GCA: Sulfur extraction via carbonated melts from sulfide-bearing mantle lithologies – Implications for deep sulfur cycle and mantle redox

/0 Comments/in /by

Proteek Chowdhury and Rajdeep Dasgupta Abstract Transport of sulfur via mantle-derived partial melts from deep Earth to the surface reservoirs is a critical step in the deep global sulfur cycle. Given that sulfur is stored mostly in sulfide phases in mantle lithologies, the critical parameter is sulfur concentration at sulfide saturation (SCSS) of mantle-derived magmas. […]

Effect of sulfate on the basaltic liquidus and Sulfur Concentration at Anhydrite Saturation (SCAS) of hydrous basalts- Implications for sulfur cycle in subduction zones Proteek Chowdhury, Rajdeep Dasgupta To add to our understanding of sulfur cycle in subduction zones in general and constrain the effects of slab-released sulfate (SO42−) on the magma genesis and sulfur […]
