Résumé des Résultats Majeurs (en anglais) :
Bulk composition of the Earth: (i) We refined the “Enstatite Chondrite” (EH) model of the Earth (Javoy et al. 2010). The aim was to make the chemical model compatible with as many available geophysical and geochemical constraints as possible. This led to a reevaluation, compared to previous models, of the primordial fractions of silicate, metal and sulfur initially present in the accreted meteoritic material. (ii) A few years later, my PhD student and I evaluated the potential role of collisional erosion on the bulk composition of the Earth at the end of the accretion (Boujibar et al., 2015). We found that some major problems of the EH model can be overcome by the erosion of a proto-crust by meteoritic impacts, especially if the collisional erosion is less efficient for the most refractory chemical components.
Early core-mantle interactions: (i) Based on experimental determination of the metal-silicate partitioning, we demonstrated that the hydrogen is much less siderophile (iron loving) than previously reported (Clesi et al., 2018). Our results suggest a level of ~60 ppm in the core and water preferentially segregated into the planetary mantles. When comparing the present-day H-content in the mantle and the amount of H present in the meteoritic material, our results suggest that 90% of the water was lost during the early accretion processes. (ii) The partition coefficients of K, Pb and U between metal and silicate indicates that these elements are not highly siderophile in conditions of the core-mantle segregation, especially if the S-content in the core is moderate (Bouhifd et al., 2007, 2013). Consequently, the radiogenic sources should play a minor role in the heat budget of the Earth’s core along its history.
Crystallization of the magma ocean and secular cooling of the deep Earth: (i) We refined melting curves, solidus and liquidus, of the primitive chondritic-type mantle relevant to the deep Earth’s mantle (Andrault et al. 2012). Major implications arises, in particular the present-day temperature of the core-mantle boundary at ~4000 K (Andrault et al., 2016). (ii) We also refined the thermal state of our planet during the crystallization of the magma ocean (Monteux et al., 2016) and demonstrated that the temperature of the young Earth’s core, several M-years after the giant Moon forming impact, can hardly be hotter than ~300 K more than it is today (Andrault, 2019). (iii) We refined the Fe partition coefficient between the melt and the mantle residue in the conditions of the very deep mantle (Andrault et al., 2012). We show that even though Fe is an incompatible element, it does not concentrate strongly into the melt. Therefore, it is unlikely that the major lower mantle phase, bridgmanite, becomes buoyant at the early stages of the magma ocean crystallization. This makes unlikely the early formation of a basal magma ocean.
A geodynamo favored by the presence of the Moon: It is an opened paradox that the core temperature at the core-mantle boundary only changed by ~300 K along the Earth’s history (Andrault et al., 2016; Monteux et al. 2016), while classical models of core cooling require a temperature change 5 to 10 times larger to power the geodynamo by thermal convection in the outer core. We proposed a model to overcome this paradox based on the mechanical forcing (solid tides, precession and libration) on the Earth due to the presence of the Moon. In this model, the core cooling would be slow and the inner core would have appeared 2-3 Ga ago.
Final mantle crystallization at the Archaean to Proterozoic transition: Our new determination of the solidus profile in the upper mantle provides a potential explanation for the change of mantle dynamics, from regimes of “stagnant lid” to “plate tectonics”, about 2.5 Ga ago around the Archaean to Proterozoic transition (Andrault et al., 2018). During the Archaean, a mantle layer could have remained partially molten at mantle depths between 100 and 300 km, due to a mantle potential temperature 200-300 K higher than today. Then, the molten layer progressively disappeared with secular mantle cooling, possibly favoring the change of mantle-dynamic regime. A residual trace of this molten layer could be the low-velocity seismic zones observed today at a mantle depth of around 80 km.
Impact of the redox state of the deep mantle on the Great Oxygen Event: We developed the proposal that the Great Oxygen Event (GOE), which had a major impact on the development of life on Earth, could be linked to the large amount of ferric iron (Fe3+) that can be stored in (Mg,Fe)(Si,Al)O3 bridgmanite, the major phase of the deep mantle (Andrault et al., 2018). The primordial mantle could have maintain an excess Fe3+ during the Archaean, when the deep mantle material remained more insulated from the Earth’s crust. Then, an improved mantle mixing favored by deep subduction of slabs could have mantle induced the release of a large amount of oxygen at the Earth’s surface about 2.5 Ga ago.
Thermal state of the deep Earth: We performed an accurate determination of melting curves (solidus and liquidus) of the primitive chondritic-type mantle (Andrault et al., 2011) and of various Fe-alloys (e.g. Morard et al., 2014). Based on the seismic observation of partially molten ultra-low velocity zones in the lowermost mantle and the well-defined size of the inner core, we could refine a most accurate temperature profile in the deep Earth. Temperatures of ~4100 K and ~5600K are likely to prevail at the core-mantle boundary and surface of the inner core, respectively. It results a temperature change of 1250-1500 K in the first few hundred kilometers of the lowermost mantle. Such temperature change can induce the melting of the subducted basaltic crust at the core vicinity, possibly explaining the ultra-low velocity zones detected by seismology (Andrault et al., 2014).
Petrological interpretations of the low-velocity seismic regions: (i) We compared experimental measurements of Vp and Vs sound velocities for various mixtures of melt and olivine with the seismic signature of the low-velocity layer atop the mineralogical discontinuity at 410 km depth in the upper mantle (Chantel et al., 2016; Freitas et al., 2017). Our results show that a low-degree of partial mantle melting, less than 1%, is very compatible with the seismic anomalies. (ii) We proposed that the ultra-low velocity zones evidenced by seismology in the lowermost mantle could be explained by the partial melting of the basaltic component of the subducted slabs (Andrault et al., 2014). Indeed, basalt presents a solidus ~350K lower than the mean mantle at the pressure of ~135 GPa.
Crystal chemistry of the lower mantle: (i) The diversity of stable minerals decreases rapidly with increasing mantle depth; however, it does not make the mineralogy much simpler. Indeed, the crystal chemistry of each phase is complicated by the effects of pressure, temperature and the presence of a number of atomic defects. For many years, I investigated the effect of Al and Fe3+ and other atomic defects on the properties of high-pressure minerals, such as bridgmanite, stishovite and CaSiO3-perovskite. (ii) We showed that pressure favors largely the coupled substitution of different atomic defects together in a same structure. This is particularly the case for Fe3+ and Al3+ in bridgmanite (Andrault et al. 2007). Concerning bridgmanite in the lower mantle, up to 40% of its iron adopt the valence Fe3+ at the highest pressures (Andrault et al., 2018). Such a high Fe3+ content can only be associated with the presence of metallic Fe0 for a typical mantle composition. Many other elements can be inserted in the structure of bridgmanite following the same mechanism (Andrault, 2003), however, the very large elements such as U4+ adopt the lattice of the CaSiO3 perovskite-type phase (Gréaux et al., 2009). (iii) The insertion of Al in the lattice induces a significant distortion of the unit cell lattice. In stishovite, it favors the phase transformation to the CaCl2-type polymorph at much lower pressure than for the Al-free sample (Bolfan-Casanova et al., 2009). In addition, it favors the coexistence of (Fe,Al)-bearing bridgmanite and post-bridgmanite phases in a large range of depth in the lowermost mantle (Andrault et al., 2010).
Elastic properties of deep mantle Minerals: (i) After studying carefully the response of various minerals to increasing pressures and temperatures (e.g. Andrault et al. 1991, 1995, 2001), I participated to the first structural refinement (Andrault et al., 1998) and determination of PVT equation of state (Fiquet et al., 1998) at experimental conditions relevant to the deep mantle. This information was subsequently used to model the deep mantle mineralogy, based on seismic records. For example, we proposed that the lowermost mantle could be relatively depleted in MgO compared to the peridotitic upper mantle (Samuel et al., 2005). (ii) We showed that Al-defects do not have a large impact on the PVT equation of state of stishovite (Bolfan-Casanova et al., 2009) and bridgmanite (Andrault et al., 2007). (iii) We determined the compression behavior of hollandite and the associated phases typical of the basaltic composition in the lower mantle (Guignot et al. 2007). Our results show that the basaltic fraction of the subducted oceanic lithosphere remains denser than the peridotitic mantle at all mantle depths. It could therefore sink down to the lowermost mantle.
Solid-state chemistry: Based on our experimental developments, we invited applications from solid-state chemistry to our experimental and analytical tools. The published works in the domain of new B-C-N based hard materials received a high number of citations. It concerns in particular the first mixed compound between diamond and cubic-BN (Solozhenko et al., 2001), which composition BC2N and its structure was obtained based on Rietveld refinements. We also synthesized diamonds with very high boron content (Solozhenko et al., 2009) and new low-compressibility carbon nitride polymorphs (Goglio et al., 2009).

Développements Instrumentaux Majeurs :
Amélioration de la ligne de lumière ID27: la nouvelle ligne de lumière est en cours de conception, en même temps que tout l’anneau de l’ESRF est reconstruit pour aboutir à la Source Extrêmement Brillante de l’ESRF. Les gains attendus sont un flux de rayons X ~100 fois plus intense et une taille de faisceau ~10 fois plus petite sur l’échantillon, comparés à l’ancienne ligne ID27. Environ 70 chercheurs de 34 institutions scientifiques européennes contribuent à ce projet.
Acquisition d’un appareil à double faisceau (SEM-FIB) au LMV, dans le cadre de la création de la plateforme CarMa pour la caractérisation avancée des matériaux géologiques. Nous travaillons activement à la mise en place d’un ensemble d’outils analytiques à la pointe de la technologie permettant de réaliser des tomographies physiques et chimiques en 3 dimensions pour différents types d’échantillons: échantillons synthétiques préparés en cellule à enclumes de diamant et en presse à multi-enclumes, échantillons naturels tels que des inclusions vitreuses et des échantillons d’intérêt industriel. Cela implique l’acquisition d’un microscope électronique couplé à un faisceau focalisé d’ions, ainsi que d’un nano-tomographe à rayons X.
Chauffage laser dans la cellule à enclume de diamant au LMV: Nous avons mis en place et développé ce nouvel outil de 2015 à 2018. Actuellement, nous effectuons régulièrement des expériences pour (i) déterminer les propriétés de fusion de matériaux géologiques à grandes profondeurs, (ii) le recuit d’inclusions vitreuses à diverses conditions de pression et de température et (iii) nous préparons des outils pour la détermination in situ de la conductivité thermique.
Diffraction des rayons X dans la presse à grand volume: Entre 2013 et 2016, la LMV a dirigé le développement et l’installation d’une presse à multi-enclumes sur la ligne de lumière haute pression PSICHE du synchrotron SOLEIL. Le module de compression et le système de chauffage ont été conçus et mis en place par le LMV-OPGC. La presse est ouverte au programme général d’utilisateurs de SOLEIL depuis 2016.
Mesures in situ dans la presse à grand volume: Après l’installation de la nouvelle presse à gros volume au LMV en ~2010, nous avons développé un ensemble de mesures in situ des propriétés des échantillons mantelliques: conductivités électrique et thermique et vitesse de propagation des ondes acoustiques.
Nouvelle presse à gros volume de 1500 tonnes: Une nouvelle presse à gros volume a été achetée par le LMV en 2009. Nous avons opté pour une presse de pointe de 1500T associée à un système de chauffage original conçu pour minimiser le bruit électrique lors des expériences in situ. Cette presse est un Instrument National de l’INSU-CNRS
Chauffage au laser en cellule à enclumes de diamant à l’ESRF: Il y a plusieurs années, j’ai activement participé à la mise en place de l’une des premières expériences de chauffage au laser dans la cellule à enclumes de diamant couplée à la diffraction des rayons X sur anneau synchrotron. Cet outil fournit des informations uniques sur les propriétés des matériaux dans des conditions extrêmes de pression et de température. Aujourd’hui, des systèmes comparables sont développés sur la plupart des installations synchrotrons de 3ième génération, couplés à différents types de techniques analytiques.
