Abstract:
Cation, anion (including halogens), stable isotope (O, H, Cl, Li, B), and 3He/4He geochemical data of fluids from Costa Rica outer forearc, forearc, and arc springs. Spring fluids are from cold and hot springs. Fluid chemistry reflects contributions from differing subducting slab sources, with some late modification (e.g., fluid-rock interaction, kinetic fractionation due to phase separation). Data can be used to evaluate volatile recycling through the forearc and potential changes in fluid source from the dehydrating subducting slab.
