By Laura Paddison, CNN (CNN) — A mysterious type of magma found within extinct volcanoes scattered around the world could contain an abundant supply of rare earth elements, crucial ingredients ...

July 29 (UPI) -- New research suggests a surprising diversity of magma types, including potentially explosive magma, can be found hiding within the pipes of seemingly reliable volcanoes. Some ...

When magma erupts or flows from the Earth, it is then called lava. There are three types of magma, according to National Geographic: Basaltic Andesitic Rhyolitic Each form has its own mineral ...

Two distinct magma types lie under Yellowstone, with basaltic magma being the primary driver of Earth's volcanic activity. Due to its lower resistance to flow, it tends to erupt more readily.

A detailed look at rocks and minerals, the essential building blocks of Earth’s crust. Rocks are naturally occurring solids ...

It is so rare, no eruptions featuring this type of magma have happened in recorded history. Instead, it is only known from extinct volcanoes that were active many millions of years ago.

Specifically, changes in the ratio of argon-40 and helium-3 can indicate how frothy the magma is, which signals the risk of different types of eruption.

A study shows how CO2 deep underground helps magma avoid being trapped deep in the Earth and allows it to reach and pool at the surface. The study “expands our understanding of the sources and ...

Scientists have spied a vast reservoir of hot, partly molten rock beneath the supervolcano at Yellowstone National Park that’s big enough to fill the Grand Canyon 11 times over.

Specifically, changes in the ratio of argon-40 and helium-3 can indicate how frothy the magma is, which signals the risk of different types of eruption.

Denser types of rocks, like olivine rich in magnesium and iron and pyroxene, a mineral found in igneous rocks formed by the cooling of magma, sank in this global magma ocean and formed the Moon ...
