Volcanic activity bubbling away beneath the Yellowstone National Park in the US appears to be on the move. New research shows that the reservoirs of magma that fuel the supervolcano's wild ...

The biggest reservoir of rhyolitic magma found by the team is located in the northeastern area of Yellowstone. Below it, basaltic magma is migrating up from the lower crust, providing heat to the ...

Rhyolitic Each form has its own mineral composition, but magma is also made of "small amounts of dissolved gases such as water vapor, carbon dioxide, and sulfur," according to National Geographic ...

Based on the volume of rhyolitic magma storage beneath the northeast Yellowstone Caldera, and the region's direct connection to a heat source in the lower crust, the researchers concluded that the ...

Rhyolitic magma, on the other hand, is much thicker and more resistant to flow. Underneath Yellowstone, basaltic magma heats the surrounding rock to help create this kind of magma in the Earth ...

The magma storage areas imaged by the magnetotelluric study are not completely molten, however, and instead consist of a mush of packed crystals interspersed with liquid rhyolitic magma.

Yellowstone National Park's geological history is one of the most intensely studied in North America. A new geologic unit ...

Rhyolite is a thick, silica rich magma that flows relatively slowly and can lead to explosive eruptions. In contrast, it is basalt—a more runny and iron/magnesium rich magma type—that wells up ...

Rhyolitic magma, on the other hand, is much thicker and more resistant to flow. Underneath Yellowstone, basaltic magma heats the surrounding rock to help create this kind of magma in the Earth ...

Be glad other types of lava aren’t as common. Both andesitic and rhyolitic magma have higher gas content and erupt much more explosively than basaltic. The supervolcano beneath Yellowstone has ...
