This provides further support for the lunar magma ocean hypothesis.” One surprise, however, was the presence of a relatively large amount of olivine, a relatively heavy magnesium-based mineral.

After an eruption sends these special olivine crystals to Earth’s surface, the magma inside them cools and becomes glass. By analyzing the chemical composition of these miniscule pieces of cooled ...

Scientists created a simulation showing that early Earth still retained chemical traces of its igneous youth, 4.5 billion years ago.

Like fortune tellers who peer into a crystal ball for insight, volcanologists at the USGS Hawaiian Volcano Observatory peer into the tiny crystals contained in lava flows to learn about the magma ...

Soil studied by India’s Chandrayaan-3 mission near the lunar south pole adds support to the theory that the moon once had a magma ocean billions of years ago. CNN values your feedback 1.

Hawaii's Kilauea volcano has been fiercely erupting for well over a month. Now, residents are finding little green gems that have fallen out of the sky during Kilauea's eruption.

The magma ocean, likely hundreds to thousands of kilometers deep, persisted for about 100 million years, the space agency says. As the magma ocean cooled, crystals formed within it.

Olivine is the earliest mineral to crystallize from basaltic magma, and accurate knowledge of olivine/melt partition coefficients (DOl-melt ) for first-transition row elements (FTREs) Ga and Ge ...
