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 ...

When two of Earth's tectonic plates collide, the heavier plate is forced underneath and back into the mantle in a process called subduction. During the early stages of newly initiated subduction zones ...

Ultrahigh-temperature (UHT; T max ≥ 900 °C) metamorphism requires unusually high heat in continental crust at depths of 15–55 km, but how such extreme thermal conditions are achieved is enigmatic. In ...

Arc magmatism is thought to have played a central role in creating continental crust because magmatic rocks — erupted as andesitic lavas and intruded to form plutons — found in subduction-related ...

Last week, Professor of Earth & Oceanographic Science Rachel Beane, with help from students, gave a talk on the craggy coast of Bailey Island, inviting the public to come learn about the unusual rock ...
