Latest Magma Stories
Scientists from the Smithsonian and the University of Rhode Island have found unsuspected linkages between the oxidation state of iron in volcanic rocks and variations in the chemistry of the deep Earth.
Scientists from the University of California, San Diego’s Scripps Institution of Oceanography (SIO) have discovered a liquefied layer of molten rock in the planet’s mantle – a substance which could be acting as a lubricant of the sliding motions of the Earth’s tectonic plates.
A new analysis shows that the impact event that formed the Orientale basin on the Moon's western edge and far side created a sea of molten rock 220 miles across and at least six miles deep.
Scientists analyzing data from NASA's MESSENGER spacecraft say that Mercury once harbored an ancient magma ocean.
Researchers for the first time have discovered evidence supporting the theory that the processes that act as catalysts for volcanic activity today are similar to those that occurred nearly four billion years ago.
According to a new study, the Earth's mantle magma melts far hotter and deeper in the Earth's core than previously thought, a discovery that will have lasting implications for geologists.
Even though two-thirds of the Earth's solid surface is covered with oceanic crust, scientists still don't entirely understand the process by which it is made.
From Pompeii to Mount St. Helens, we humans have watched in awe, and sometimes horror, the magnificence of volcanic eruptions.
Scientists have identified a trigger for the largest explosive volcanic eruptions on Earth, according to a report published in the journal Scientific Reports.
How often have you wished you could safely see a lava flow, like the one that destroyed Pompeii? Did you ever wish you could see it in Syracuse, New York?
Scoria is a term used by geologists to describe an igneous rock containing many gas bubbles, or vesicules. Scoria forms when magma rich in dissolved gases is vented. As the magma encounters lower pressures, the gasses are able to escape and form bubbles. These bubbles are trapped when the magma cools and solidifies. Volcanic cones of scoria can be left behind after eruptions, usually forming mountains with a crater at the summit. An example is Mount Wellington, Auckland in New Zealand....
- The act of burning, scorching, or heating to dryness; the state or being thus heated or dried.
- In medicine, cauterization.
