Dr. Clive R. Neal. Dr. Neal uses petrology and geochemistry to investigate the environment from planetary differentiation to heavy metal pollution. Dr. Neal has been Director of the Notre Dame ICP-MS Facility since 1992 when our VG PlasmaQuad II ICP-MS was purchased. Installed in 1993, the PQII has been the workhorse for trace (ppm-ppb) and ultra-trace (<ppb) work for more than a decade. In 2004 our Finnigan Element 2 high-resolution magnetic sector ICP-MS was purchased and installed. The Element 2 significantly enhances our capability to analyze samples with complex matrices and low elemental abundances.
Research Associate Professor (& Concurrent Associate Professor)/Lab Manager:
Dr. Antonio Simonetti. Dr. Simonetti recently joined the Department of Civil Engineering & Geological Sciences as a Research Associate Professor and manager of the ICP-MS facility. Tony's ICP-MS-based research interests and publications are varied and these cover many disciplines within the Earth Sciences, and also include recent collaborations with anthropologists and medical doctors. In recent years, he has also been involved with the development of innovative laser ablation-ICP-MS techniques, such as the recent chapter contribution in the Mineralogical Association of Canada-sponsored short course entitled, "Laser Ablation ICP-MS in the Earth Sciences: Current Practices and Outstanding Issues", held at the 2008 V.M. Goldschmidt Conference in Vancouver, Canada. However, his research 'passion' remains deeply rooted with investigating the chemical nature of subcontinental mantle through the isotopic and chemical investigations of alkaline igneous rocks, such as carbonatites, nephelinites, and kimberlites. He recently accepted an invitation as a guest editor for a special issue of the journal Mineralogy and Petrology dealing with flood basaltic volcanism and associated alkaline magmatism dedicated to Dr. Keith Bell. Publication of this special issue is anticipated for late 2009-early 2010.

Former Students (Ph.D):
Georgianna Kramer. Graduated in 2007. Her dissertation is titled: On the Petrogenesis and Distribution of the High-Alumina Mare Basalts: An Integrated Approach Using Geochemical And Remote Sensing Data.
William Kinman. Graduated in 2007. Dissertation titled: Textural and Microanalysis of Igneous Rocks: Tools for Understanding Igneous Processes. Dr. Kinman is now at Oak Ridge National Laboratories.
William Chazey. Graduated in 2004. Dissertation titled: A Comparision of LIP Magmatism: Examples from the Earth and the Moon. Bill focused on the geochemistry of the Ontong Java Plateau and the Kergeulen Plateau, discovering that the platinum group element abundances of the Ontong Java Plateau require an origin of the plume at the core-mantle boundary.
Cathleen McGinnis. Graduated in 2001. Dissertation titled: The Nature of the Sub-Continental Lithospheric Mantle Beneath Northern Venezuela: Implications for Plate Collision and Magmagenesis.
Amy Birkhold-Van Dyke. Graduated in 2000. Dissertation titled: A Geochemical Investigation of the Ontong Java Plateau.
James Ely. Graduated in 1999. Dissertation titled: Analysis of Platinum-Group Elements (PGEs) and Au in Geological Materials at Ultra-Trace Levels: Techinique Development and Applications. Jim helped develop the protocol for platinum group element analysis. His work led to the precise determination of sub-ppb platinum group elements in milligram sized samples. Previously, platinum group element determinations were done by fire assays and required grams of sample.
