My main interest is to understand how mountains are formed and how they get destroyed through time. In dynamic orogenic systems, metamorphic rocks constitute exceptional chances to unravel deep geological processes using a great field of methods at all scales. My research generally combines field work and petrology with micro-analyses and currently aims at better understanding one of the most interesting, yet challenging goals in metamorphic geology: the evolution of mineral growth through time.
Insight into the tectonics and long-term evolution of the lithosphere requires reliable constrains on the link between minerals we can date and minerals that record part of the P–T evolution. Chrono-logical studies typically rely on in-situ dating of accessory minerals, such as zircon, monazite and xenotime. Nevertheless, limitations exist regarding our ability to link these age results to specific pressure and temperature information from petrogenetic indicators such as garnet.
The partitioning of specific trace elements among metamorphic minerals is generally used to link time with P–T evolution. My research focuses on trying to improve our understanding of this link, by performing multi-approach analyses that integrates trace-element geochemistry, phase equilibria modelling and multi-method chrono-logy (U-Pb in zircon, monazite and rutile; Lu-Hf in garnet). New insights into “petrochronology” will be obtained by directly comparing age results and trace element compositions from each of these minerals and systems.
