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 ...

A trio of researchers from James Cook University, working with a colleague from the University of Adelaide, has found metamorphic diamonds in rocks near Australia's northeast coast. In their paper ...

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 ...

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 ...

Sedimentary rocks are made up of pieces of older rocks (igneous, metamorphic, and sedimentary) and organic remains (shells, bone, etc.). When rocks break apart from erosion they are transported by ...

Diamond formation has typically been attributed to redox reactions during precipitation from fluids or magmas. Either the oxidation of methane or the reduction of carbon dioxide has been suggested, ...

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 ...
