RESEARCH INTERESTS
My research interests include petrogenetic processes at mid-ocean
ridges, oceanic islands and convergent margins. I am interested
in the physical and chemical conditions of partial melting, magma
extraction and segregation processes and the geochemical heterogeneity
of the Earth's mantle. Specifically my tools include:
(1) Melt inclusions trapped in the early phenocrysts of lavas, mostly
olivines. I use the major, volatile and trace element compositions
of melt inclusions and minerals to constrain petrogenetic processes
at the very early stages of magma formation and differentiation.
(2) Geochemical modeling of petrological processes for major and
trace elements (mantle melting, mixing, crystallization and transport)
(3) Experimental determination of melt/mineral trace element partition
coefficients between the minerals plagioclase, clinopyroxene, orthopyroxene,
olivine and basalt and basaltic andesite melts (in collaboration
with T.L. Grove at MIT). This data is fundamental to the modeling
of crystallization processes and the determination of the pressure
and temperature conditions of formation and equilibration of natural
samples.
