Summary of Activities/Interests

Dr. Simonetti’s research focuses on the combined geochemical, petrological and radiogenic isotope investigation of igneous and mantle-derived rocks and their constituent minerals using both ICP-MS and laser ablation-MC-ICP-MS instrumentation. This involves major and trace element, Nd-Sr-Pb-Hf and oxygen isotope and in-situ Sr and U-Pb investigations of subduction-related calc-alkaline rock suites (Saar-Nahe basin, Germany), kimberlite-hosted peridotite mantle xenoliths (Somerset Island, Canadian Arctic) and mantle eclogite xenoliths from diamond-bearing kimberlites (Northern Canada). Xenolith results are used to characterize composition and origin of the subcontinental mantle beneath North America.
