Although dolomite is relatively plentiful in rocks older than 100 million years, scientists have been unable to replicate the geologic process in the lab—until now. Using a transmission electron ...

Gold has always been a hot commodity. But these days, finding a nugget isn’t too tricky: Much of the world’s gold is mined from natural veins of quartz, a glassy mineral that streaks through large ...

Boulder, Colo., USA: Marine and coastal geoscience play a critical role in understanding ancient and modern geological history, offshore and coastal hazards, and climate change. Deep-water ...

A new analysis of rocks thought to be at least 2.5 billion years old helps clarify the chemical history of Earth's mantle -- the geologic layer beneath the planet's crust. The findings hone scientists ...
