Flow rates and reaction rates in the Galapagos Rise spreading center hydrothermal system as inferred from (228)Ra/(226)Ra in vesicomyid clam shells
The (228)Ra/(226)Ra ratios in a previously dated vesicomyid clam shell were used to determine that seawater was in contact with mid-oceanic-ridge basalt glass for 22-45 years prior to arrival to the surface at 350°C at the Galapagos Rise Spreading Center. The minimum rate of reaction for the 45-year...
