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 ...

So, another way to produce rhyolite magma is to start melting the crust that all the basalt intrudes. Basalt is hot, usually over 1200ºC, so when it rises into the crust, ...

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 ...

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 ...

Although rhyolite magma has fuelled some of the Earth's largest explosive volcanic eruptions, our understanding of these events is incomplete due to the previous lack of direct observation of ...

Hoping to better understand the properties of covert magma, Rooyakkers took samples of the magma serendipitously drilled in 2009—a goopy type known as a rhyolite—and forensically compared them ...

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 ...

New research published recently in Geology reports on the discovery of shallow pools of magma lying just beneath the Earth’s crust that are too small to be seen with traditional volcano measuring ...
