Abstract:
Gases and fluids from four geothermal fields of Central America were analyzed for nitrogen, methane, and helium concentrations, isotopic composition, and 129I/I ratios in order to determine the sources of volatiles in these systems. The magmatic flux of nitrogen and noble gases in Central America was then extrapolated to determine the degree of nitrogen recycling in island arc systems. Also contains gas data from Snyder et al 2001.
