Welcome to Celia Dalou's personal website
My research focuses in the understanding the behavior of volatile elements (H, C and N) during planetary formation combining experimental petrology, vibrational spectroscopy and state of the art analytical techniques.

ABOUT ME
I am an experimental petrologist. My research focuses on the physio-chemical effects of volatile elements (H2O, CO2, F, Cl and N) on mantle processes and their fractionation (elemental and isotopic) during core formation, mantle melting and mantle-fluid interactions.

RESEARCH PROJECTS
F and Cl fractionation during mantle melting at high P-T conditions:
Quantifying the influence of H2O and CO2 on F and Cl solubility and solution mechanisms in magmas, and the partition coefficients between mantle minerals and melts. The aim of this project is to determine if F and Cl can be used as tracers of the primary H2O and CO2 content in the mantle.
Started in 2007

Isotopic fractionation of stable elements at high pressure and temperature in silicate melts:
In-situ measurement of D/H, 13C/12C and 15N/14N fractionation between silicate melts and aqueous fluids at high P-T conditions (in a hydrothermal diamond anvil cell apparatus) constrains the stable isotopic signatures of melt inclusions as tracers of volatile cycling in the Earth’s mantle.

POSITIONS
Carbon and Nitrogen partitioning between silicate melt and Fe metal as a function of fO2, melt composition, pressure:
The partitioning of C and N can improve our understanding of the delivery and processing of C and N in growing terrestrial planets, from the distribution of these species in circumstellar disks to their partitioning during magma ocean/core formation stages of planetary differentiation.
EDUCATION
Nitrogen isotopes fractionation during mantle processes (metal/silicate melt segregation, mantle melting, fluid exsolution and degassing) as a function of fO2 and melt composition:
The present-day isotope distribution between terrestrial reservoirs shows a strongly heterogeneous distribution between the 15N-depleted mantle, and the 15N-enriched surface. As mantle degassing should preferentially remove 14N, the mantle is expected to be enriched in 15N compared to the atmosphere (Boyd et al., 1994). This expectation is contradictory to present-day observations, making the N isotope apparent disequilibrium paradoxical (Cartigny and Marty, 2013). This project should help clarify these issues.
