The role of deformation in fluid-mediated mass transfer during subduction

One of my projects concerns the distribution of major and trace elements in Alpine and Franciscan eclogites. We apply electron microprobe analysis and LA-ICP-MS to constrain the roles of deformation and fluid flow in subduction zones. Above is an SEM image of an eclogite from the Voltri Massif, showing some of the complex mineral transformations we deal with. This image was used as a map of the sample during LA-ICP-MS analysis.

This research was partly carried out under a Smithsonian Postdoctoral Fellowship, funded by the Smithsonian's Office of Fellowships and Grants, but continues today.
In collaboration with Sorena Sorensen, National Museum of Natural History, Smithsonian Institution, Washington DC, USA.
