Alan BoudreauAlan Boudreau is Professor of Geology at Duke University, North Carolina and an expert on the origins of layered intrusions. He has worked on numerical modeling of crystallization processes such as crystal aging and compaction, and how they give riseto the variety of features observed in these intrusions. He is also interested in the role of igneous fluids in the petrogenesis of platinum-group element (PGE) deposits in layered intrusions, including the understanding of interaction of igneous fluids with liquid-crystal assemblages to produce the observed features.
