Finally, micro-scale interactions between these phases regulate an ascending magma's capability to outgas, determining the eruption's explosivity. The sample in this article presents a basalt-rhyolite ...

So it’s unlikely to erupt. Rhyolitic magma, on the other hand, is much thicker and more resistant to flow. Underneath ...

The Yellowstone Caldera is often referred to as the Yellowstone Supervolcano due to its colossal size; it's one of the ...

Although the USGS identified pockets of melted rhyolite rock under all of Yellowstone, channels of magma connect the northeast rhyolite melt pockets to deeper reservoirs of molten basalt.

What scientific question(s) does your research address and what motivates this work? How did eruption tempo evolve in the Jemez Mountains Volcanic Field (JMVF) leading up to the last caldera-forming ...

These thermal features are caused by the magma reservoir underneath the park, and magma still flows to this day. According to the USGS, the new feature sits at the foot of a rhyolite lava flow about ...

Lava domes are rounded, steep-sided mounds built by magma that is highly resistant to flow, usually either dacite or rhyolite. Such magmas are typically too viscous to move far from the vent ...
