Furthermore, the researchers compared this measurement to data collected from comparable crystals created around 2,000 ...

The weakened magnetic field may have led to increased oxygen concentrations in our atmosphere and oceans, triggering an ...

Earth's magnetic field could have led to increased hydrogen escape and subsequent oxygen rise in the atmosphere. This surge ...

An unusual reduction in the strength of Earth's magnetic field between 591 and 565 million years ago coincided with a ...

Recent research brings a surprising twist to our understanding of planetary science. This new study indicates that a significant weakening of Earth’s magnetic field around 590 million years ago might ...

The glassy material maskelynite is created when the mineral plagioclase is exposed to extreme pressure like those caused by giant impacts. That means finding maskelynite within the rock can hint ...

As this ocean cooled and crystallized, it formed the distinct layers we recognize today: a mafic mantle and a ...

Analytical and high-resolution transmission electron microscopy of weathered plagioclase and K-feldspar provided microtextural and chemical data that suggest a sequential formation of weathering ...

Gardner and Abbott currently are using various microscopy techniques to analyze eight lunar simulants — faux moon soil that is designed to mimic the real thing — and synthetic plagioclase, a brittle, ...
