Understanding the timing of formation and the processes of differentiation and volatile depletion of terrestrial planets. To reach these goals I develop and use high precision isotopic measurements.
During my PhD, I used Cr which is a very well suited element as in includes stable isotopes (to study the processes), radiogenic daughter of 53Mn (to study the timing) and nucleosynthetic anomalies 54Cr (to study the origin). I combine these three approaches by using both TIMS and MCICPMS, unspiked (radiogenic and nucleosynthetic anomalies) and double spiked (stable isotopes).
1. Cr isotopic anomalies in meteorites.
I have measured by both TIMS and MCICPMS the mass-independent Cr isotope variations produced by both radiogenic ingrowths to study the timing (e.g. 53Mn-53Cr chronometry) and nucleosynthetic anomalies to study the origin (54Cr) of primitive meteorites, their main components (chondrules) and planetary bodies (including Mars, Angrite, Ureilite, and Aubrite parent bodies).
2. Cr stable isotopic compositions (mass-dependent fractionation) in meteorites.
I use an original approach by measuring Cr stable isotope variations (using double spike approach coupled with a MCICPMS) to study the volatile loss, magmatic evolution, and core-mantle differentiation of terrestrial planets (Mars, Vesta, Angrite, Ureilite, and Aubrite parent bodies).
