Hydrothermal Minerals Record Variations in CO2 Flux of the Mid-Atlantic Ridge: Reykjanes Geothermal System, Iceland
Abstract/Contents
- Abstract
- The Mid-Atlantic Ridge spreading center is exposed on land at the Reykjanes geothermal system in southwest Iceland. Seawater that penetrates this coastal geothermal system at depth reacts with the host rock basalt to form secondary geothermal minerals in progressively higher-grade mineral alteration zones with depth at temperatures over 300C. Within several alteration zones, epidote, prehnite, calcite and quartz form a trivariant assemblage that, under conditions of specified temperature and pressure, allows predictions of geothermal fluid pCO2 to be made as a function of the composition of the solid solution minerals epidote and prehnite.
