My research, as PhD student and MAGNET trainee, focuses on the isotopic composition of layered intrusions. Large layered intrusions are natural laboratories for studying differentiation and crystallization. Minerals coexisting in cumulates within a single mafic layered intrusion have long been considered to have crystallized from the same magma and thus should share the same radiogenic isotopic compositions. Yet, significant radiogenic isotopic differences, at the time of formation, are increasingly documented between coexisting minerals from mafic layered intrusions. These differences are not related to secondary alteration, thus either the minerals crystallized from magmas of different isotopic compositions or concomitant magmatic processes disturbed their primary isotopic signatures. To investigate the extent and cause of these isotopic variability, I am analyzing lead, strontium, hafnium, and neodymium isotopic compositions of coexisting minerals in the Kiglapait intrusion, Labrador (Canada), considered to represent crystallization from a single injection of magma under closed system conditions.

Lab work

Preparation of samples in clean-lab, Pb-Sr-Nf-Hf extraction column chemistry. Use of  ICP-MS (ElementII and Attom) and MC-ICP-MS (NP21, NP214 and NP1700).

Internship at the Nu Instrument Ltd, UK, April 2014

Test of different sample introduction methods on the NPII to define the origin of the mass bias during the analysis of Fe isotopes.

Master Research Project

Institut des Sciences de la Terre, Grenoble (France).

Supervisors: Dr. Catherine Chauvel and Dr. Shasa Labanieh.

Summary: Study of major, trace element behavior and Pb-Sr-Nd-Hf isotopic compositions to constrain the nature, alteration processes and the source of the crust of the Shikoku basin.
