Next time you walk the Marginal Way or gaze out at Nubble Light, take a moment to look down. You may find yourself standing ...

The Rock Cycle is Earth's great recycling process where igneous, metamorphic, and sedimentary rocks can all be derived from and form one another. Analogous to recycling a Coke can, where an old can ...

Researchers have discovered microdiamonds in the Nishisonogi metamorphic rock formation in Nagasaki Prefecture, Japan. Microdiamonds in metamorphic rocks are important minerals because they form in ...

Some rocks are very common on earth. Large portions of the continents consist for example of granite and basalt covers almost all of the oceanic crust. Other rocks are formed only when very specific ...

A new study of rocks that formed billions of years ago lends fresh insight into how Earth's plate tectonics—the movement of large pieces of Earth's outer shell—evolved over the planet's ...

High-pressure metamorphic rocks form during subduction of Earth’s crust to mantle depths at convergent plate margins. Their exposure at the surface of Earth today provides a record of the subduction ...

Researchers have produced a new estimate for the origin of Earth's plate tectonics—the movement of large chunks of the planet's outer layer, or crust. Although there is broad consensus that plate ...

We often talk about climate change, melting glaciers, or strange landforms. But we rarely think about something that’s always around us– rocks. They don’t make the news, but they’re everywhere. We ...

Feldspar is the name of a group of rock-forming minerals which make up as much as 60% of the Earth's crust. Feldspars crystallize from magma in both intrusive and extrusive rocks, and they can also ...
