Research Direction

My research focuses on the geochemical and mechanical effects of fluids/rock interaction in active tectonic settings. Areas of particular emphasis include: Metamorphic core complexes and shear zones (Cyclades, Greece; D'entrecasteaux, Papua New Guinea); active seismogenic faults (Nojima, Japan); Fourier transform imaging (FTIR) of fluids in rocks; oxygen isotopes; fluid and melt inclusions, volcanoes (Piton de la Fournaise and Piton des Neiges, Réunion hotspot).

Recent works



MAGMA INJECTIONS IN A VOLCANIC DETACHMENT

 

This work reports the discovery of a detachment within reach of structural investigation in a basaltic volcano (Piton des Neiges, La Réunion hotspot). The detachment is a slip zone between the top of a gabbroic magma chamber and a debris avalanche. Our structural description of this unique exposure shows that the detachment was active during the shield building stag. The fault was repeateadly intruded by basic sills, allowing furter slip during and between eruptions (Famin and Michon, in press).

 


  PLUMBING SYSTEM OF A HOTSPOT VOLCANO

 
 

 Combined analysis of whole rocks, melt inclusions and matrix glasses of Piton de la Fournaise products unravel three stages of magmatic differentiation. The deepest (> 7.5 km depth) is dominated by clinopyroxene crystallization (Line 1). Above (2.5 km), fractionation is dominated by olivine, yielding steady state basalts at the top of the chamber and picrites at its bottom (Line 2). In shallow cooling dykes and subsurface pockets of magma, melts become more differentiated by clinopyroxene+plagioclase fractionation (Line 3). The shift from one differentiation line to the next is pressure dependent (Famin et al., 2009).


 

CO2 DEGASSING IN ACTIVE FAULTS

 

Fourier Transform Infrared microscopy (FTIR) allows to map water and carbon concentrations in natural glasses at the micro-scale. FTIR mapping of two generations of pseudotachylytes (i.e. friction melts) from the Nojima fault (Japan) reveals that 90 wt% of the CO2 is exsolved during fault slip, due to the low solubility of carbon in melts. Earthquakes are therefore a significant source of CO2 (Famin et al., 2008).
