Research Topic: Sulfur transport and origin in the Icelandic crust
The focus of my project is fluid-rock-interaction in the oceanic crust. Iceland is the only place where a mid-ocean ridge lies above the sea surface, which makes Iceland the perfect research area for this study. The main focus of the project is to model changes in the sulfur content of altered rocks in active hydrothermal systems along rift zones in Iceland. A distinction is made between systems fed by seawater and systems fed by meteoric waters. The sulfur difference (delta S) is calculated using the mass balance. Mass balancing is used as a basis for sulfur fluxes to determine how much sulfur is stored in hydrothermal areas along rift zones and how much is released into the atmosphere and groundwater.
