Phenocryst or not? Using a stratovolcano’s crystal cargo to explore crustal-scale magmatic systems through time Open
Phenocrysts in magmas are often assumed to be the product of crystallization directly from a host magma. However, decades of research suggests that crystals carried in magmas (crystal cargo) are far more complex. We test the hypothesis tha…

An appraisal of the observed crystallinities of volcanic materials Open
There is a broad consensus that magma eruptibility—the ability of magma stored in the subsurface to erupt onto Earth's surface—is strongly controlled by viscosity. Related to this, a critical parameter that controls viscosity is crystallin…

Magma mingling and ascent in the minutes to hours before an explosive eruption as recorded by banded pumice Open
High-threat explosive silicic eruptions commonly contain banded pumice, reflecting magma mingling in the conduit prior to or during eruption. Heterogeneities in tuffs have been attributed to the draw-up of compositionally distinct magmas, …

Coexisting Discrete Bodies of Rhyolite and Punctuated Volcanism Characterize Yellowstone's Post‐Lava Creek Tuff Caldera Evolution Open
Ion‐microprobe 206 Pb/ 238 U geochronology and trace element geochemistry of the unpolished rims and sectioned interiors of zircons from Yellowstone caldera's oldest post‐caldera lavas provide insight into the magmatic system during the pr…
