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 ...

A collaboration of researchers based in Kumamoto University, Japan have discovered microdiamonds in the Nishisonogi metamorphic rock formation in Nagasaki Prefecture, Japan. Microdiamonds in ...

Metamorphic rock is the result of the transformation of a pre-existing rock type, the protolith, in a process called metamorphism, which means "change in form". The protolith is subjected to heat and ...

Igneous and metamorphic petrology represent two fundamental branches of geological science that elucidate the formation, transformation, and evolution of Earth’s solid materials. Igneous petrology ...

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 ...

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 ...

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 ...
