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.

Petrogenesis of the Merensky Reef: The hydromagmatic (“Uppers”) model
Journal Article South African Journal of Geology · September 1, 2025 This work presents a review of the evidence for volatile fluids and models that illustrate how such fluid can give rise to the Merensky Reef and associated stratigraphic features. The unusually Cl-rich nature of the rocks below the Merensky are consistent ...

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 ...
