I study patterns of episodic continental arc magmatism at many scales to build on our understanding of: 1) the spatial and temporal record of magmatism in arcs, and how magma sources evolve; 2) the ...

This process can occur either below the Earth’s surface, forming intrusive or plutonic igneous rocks like granite, or at the ...

There is a time-dependent chemical variation in the volcanic and plutonic rocks at Cerro Chirripó National Park. The thickened arc crust contributes to magma stalling at deeper conditions, leading to ...

At Wyoming, my students and I use such an integrated approach to shed light on the petrogenesis of a diverse range of volcanic and plutonic rocks. A fully automated electron microprobe is used to ...
