The studies will focus on various processes (e.g., alteration of planetary surfaces, hydrthermalism, phase stbility under different thermodynamical conditions).

They interact with rocks (including ices) in terms of composition (magmatism, metamorphism, metasomatism, weathering) and shape (deformation, erosion, sedimentation).

In the region, the end of the Rigolet orogeny, at 0.95 Ga, is accompanied by the Lesueur alkaline intrusion and sodic-calcic hydrothermal activities associated with extension faults.

We are working on spectral criteria (infrared absorption), which can be used to differentiate between certain minerals (phyllosilicates and opals) formed as a result of hydrothermal circulation and those formed as a result of supergene deterioration.

This is important, because the presence of molecular hydrogen indicates the water is reacting with rocks at the bottom of Enceladus’ ocean via hydrothermal processes (such as a hydrothermal vent).
