Seismic imaging of the Yellowstone system has also identified a deeper magma body, likely composed of basalt — Earth’s most ...
likely composed of basalt — Earth’s most primitive magma type and the heat engine that helps to generate and sustain the shallower rhyolite magma chamber. Magnetotelluric imaging also reveals ...
A map of the magma reservoirs under Yellowstone. Yellow represents basalt, red rhyolite, and orange basalt-to-rhyolite transition zones. The purple triangles are the magnetotelluric monitoring ...

Where the Yellowstone Volcano Will Erupt Nextchannels of magma connect the northeast rhyolite melt pockets to deeper reservoirs of molten basalt. Magma made of rhyolite produces characteristic volcanic ash, but basalt is the real driver of ...
Detailed price information for Hercules Metals Corp (BIG-X) from The Globe and Mail including charting and trades.
That movement has now left one pool of molten material on the west of the caldera disconnected from any heat sources, which will likely allow it to cool. Meanwhile, the largest pool of near-surface ...
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 ...
