Geothermal research

Piton des Neiges, the largest volcano of La Réunion, is inactive since at least 12000 years, and yet shows multiple signs of hydrothermal activity as thermal springs, fumaroles, and secondary mineralization. This hydrothermal activity suggests that the volcano has potential for geothermal exploitation, which may help La Réunion in its urgent need of renewable energy sources.

Our research aims at better understanding of the geology of Piton des Neiges in order to assess its geothermal potential. Of particular importance are the nature and location of the heat source, the fate of fluids circulating through the edifice as well as the temperature reached by these fluids. This research is highly related to the volcano-tectonics of basaltic volcanoes, which is also studied by our team.

The chosen methodology combines structural geology and field hydrogeology with rock and fluid geochemistry (elemental and isotopic) to track the transfert of fluids through the volcano.

Deformation and intrusive activity of basaltic volcanoes

Figure 15 in Chaput et al., JGR (2014)

Comparison of spreading processes for Hawaï and La Réunion (Fig. 15 in Chaput et al., JGR 2014). In Hawaï, the driving mechanism is the creep of a gigantic cumulate body alimented by vigorous magma supply. In La Réunion, spreading is due to the repeated injection of intrusions, mostly sills, in the edifice.

Most volcanoes undergo gravitational deformation, known as spreading. In the case of basaltic volcanoes spreading has puzzled scientists for decades, because the gentle slopes of the edifices (generally less than 10°) should guaranty their stability. Nevertheless, spreading is observed or inferred on many active basaltic volcanoes, and the driving mechanisms are still a matter of scientific debate.

Our work focuses on the study of internal deformation of basaltic volcanoes, and its relationship with intrusive activity. We take advantage of the unique situation of La Réunion Island that allows the comparison of two volcanoes: Piton de la Fournaise, one of the most active volcanoes on Earth and currently undergoing a deformation of its eastern flank during eruptions; provides insights on active spreading processes. Piton des Neiges, deeply incised by erosion, allows to understand how the internal architecture of the edifice impacts spreading.

Our research showed that spreading of the two volcanoes proceeds by sector collapse. Sector collapse is triggered or enhanced by the repeated injection of sills in the edifices. This mechanism is very different from the spreading of hawaiian volcanoes, thought to be related to the creep of hot cumulates.

Fluid/deformation interactions in accretionary prisms

Accretionary prisms are responsible for the greatest earthquakes on Earth, generally caused by the rupture of major faults in the overriding plate. Forecasting such earthquakes is a long reach, and for the time being it is important to understand the chemical mechanical response of accretionary prisms to the tectonic stress imposed by convergence.

Our research is focused on deciphering the mechano-chemical processes at stake in deformation zones of accretionary prisms. Particular attention is being paid to the budget of pore fluids because the pressure of these fluids potentially has dramatic effects on seismogenesis. We track processes of fluid production and consomption in deforming rocks, put quantitative constraints on these processes, and assess the effect of these fluids on the style of deformation. Our work is concentrated on the fossil accretionary prism of the eastern Japanese, where it is possible to study the nature and repartition of deformation from the accretion front to the most internal zones of the prism.
