International group of researchers involving geologists from Wits University (Prof. Rais Latypov and Dr. Sofya Chistyakova) in Johannesburg have come up with an unexpected conclusion that basaltic ...

Researchers have discovered that some seemingly "monotonous" volcanoes with reliable patterns of low-level activity may be hiding a secret deep below the surface—magma which has the potential to erupt ...

EUGENE, Ore. - July 17, 2020 - Uplifting of Columbia River basalts has allowed University of Oregon researchers to better understand of how magma 14-16 million years ago shaped the region and why ...

Scientists examine a large dike, formed from a sheet of magma that came to Earth’s surface millions of years ago during the Columbia River Basalt eruptions. These dikes fed magma to massive eruptions.

In addition to shaping the interior of rocky planets, molten rock located deep within these planets may also contribute to ...

Billions of years ago, parts of Greenland were a molten sea, a sharp contrast to the pale-blue ice seen there today. Researchers have now found isotope signatures of that burbling, primordial Earth in ...

United States Geological Survey (USGS) scientist Mark Stelton (left) and Kenneth Sims, a UW professor of geology and geophysics and a member of the USGS Yellowstone Volcano Observatory, examine a ...

Basaltic magma chambers may develop as large bodies of crystal-free melts in the Earth's crust. This study challenges a recently-emerged paradigm that magma chambers are huge masses of crystal-rich ...

Information drawn from analyses of oxygen and hydrogen isotopes of materials from exposed Columbia River basalts has provided insights about how magma from volcanic eruptions millions of years ago ...
