An international team of volcanologists working on remote islands in the Galápagos Archipelago has found that volcanoes which reliably produce small basaltic lava eruptions hide chemically diverse ...

Along the course are narrow basalt gorges and towering basalt columnar joints formed from lava that erupted around 500,000 to ...

One way to find water worlds beyond our solar system could be to look for minerals — or more specifically, to study minerals mixed with cool lava on exoplanet surfaces. This is because if water ...
