Thèmes de recherche

Research Interests : Low temperature thermochronology, isotope geology, long term landscape evolution, plate tectonics, structural geology, geomorphology.

My current research focusses on developing apatite fission track and (U-Th)/He thermochronology techniques with particular focus on passive continental margins and slowly cooled cratonic interiors. The project will implement LA-ICP-MS fission track analysis and establish the analytical capability to measure He concentration and diffusion profiles for (U-Th)/He and 4He/3He analysis. In order to advance apatite thermochronology two main questions will be addressed :

  • To what extent does chemical composition in apatite (e.g. REEs, Cl, F, OH) influence fission track and radiation damage defect annealing in apatite
  • Can multiple single-grain AHe analysis of fragmented crystals (Frag-AHe) rival the thermal history information obtained from 4He/3He analysis ?

In collaboration with colleagues at University of Paris Sud and Trinity College Dublin, new apatite fission track, (U-Th-Sm)/He and 4He/3He data will be acquired and interpreted alongside compositional data and electron microscope imagery to better understand the role of chemical and structural heterogeneity in apatite. New insights will then be incorporated into a Bayesian numerical modelling approach to extract more robust predictions of the samples thermal history.

In addition to the above, I am still actively involved in thermochronology research projects in West and South Africa.
