Project Abstract 

Project investigate chemical changes and rock alteration in vicinity to magma near the roots of active geothermal systems with the aim of improving the understanding of the interaction between the magmatic and hydrothermal system. The project is taking outset in two active geothermal systems; Krafla and Þeistareykir, in N-Iceland. The objective is to compare through analyses of hydrothermal alteration and chemical analysis of fluid inclusions (major, trace, gasses and isotopes) of cuttings from wells that have reached parts of a geothermal reservoir impacted by magmatic gasses. It constrains the chemical processes and model the magmatic fluxes at the transition zone between the magmatic and hydrothermal system.
