Overview
Boudreau's expertise lies in origins of igneous layering: Numerical modeling of postcumulus processes such as crystal aging and compaction and how they can give rise to the variety of features observed in igneous layering. Petrogenesis of platinum-group element (PGE) deposits in layered intrusions and associated work on degassing of crystal assemblages and evidence for the mixing of igneous fluids with liquid + crystal assemblages.

A Comment on ‘Postcumulus Processes Recorded in Whole Rock Geochemistry: A Case Study from the Mirabela Layered Intrusion, Brazil’ by S.J. Barnes and M. Williams
Journal Article Journal of Petrology · April 1, 2025 In their analysis of whole-rock data from the ultramafic section of the Mirabela Layered Intrusion, Barnes and Williams suggest that the rocks formed as a closed system of crystals + trapped liquid and that compaction played essentially no role in the form ...

Journal Article Mineralium Deposita · March 1, 2025 Several lines of evidence, including hydrous melt inclusions and unusually Cl-rich apatite, have been used to suggest that the reappearance of olivine and PGE-sulfide of the J-M Reef in the Stillwater Complex, Montana, is due to fluid infiltration and hydr ...

Journal Article Journal of Petrology · April 1, 2024 The presence of pegmatoid bodies in the Stillwater Complex is poorly understood, but they have been suggested to have resulted from the presence of fluids in the complex. To better understand the origin of the pegmatoids and to trace the possible influence ... Full text CiteRecent Grants
