Sulfur partitioning between aqueous fluids and felsic melts at high pressures: Implications for sulfur migration in subduction zones

Scientific Reports
Sulfur (S), an essential volatile in subduction zone magmatism, exhibits higher solubility in aqueous fluids compared to silicate melts. Despite its importance, the partitioning of S between aqueous fluids and silicate melts under the conditions of ...

Geochemistry of trace metals in the Scheldt estuary [PDF]

, 1999
The distribution of trace metals has been studied in abiotic compartments of the ScheIdt estuary (water column and sediments). Seasonal surveys, carried out in 1987-1988, indicate that the geochemistry of dissolved trace metals (Cd, Cu, Zn) is ...

Pegmatite lithium deposits formed within low-temperature country rocks

Nature Communications
The global climate crisis is likely to lead to a potential supply risk of lithium (Li) over the coming decades. More than half of the world’s production of Li is derived from Li-bearing pegmatites.

Chlorine isotopic compositions of deep saline fluids in Ibusuki coastal geothermal region, Japan: using B–Cl isotopes to interpret fluid sources [PDF]

, 2015
We report chlorine stable isotopic compositions (δ37Cl, expressed in ‰ relative to the standard mean ocean chloride) as well as δ2H and δ18O values of deep saline fluids taken at eight drill-holes reaching from 73 to 780 m below sea level in the Ibusuki ...

Oxidation state of Cu in silicate melts at upper mantle conditions

Scientific Reports
Beyond its economic value, copper (Cu) serves as a valuable tracer of deep magmatic processes due to its close relationship with magmatic sulfide evolution and sensitivity to oxygen fugacity (fO2).
