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 ...

When we look at the solid ground beneath our feet, it’s easy to assume Earth has always been this way. But our planet tells a story so extraordinary, so filled with dramatic transformations and ...

From ecosystem change and soil quality to hydrology and natural hazards, Earth studies have never been so important. But in a crowded field of concerns, how can researchers prioritise the most ...

Previous models of Earth's recent (100 million years) geomorphology have been patchy at best. For the first time a detailed continuous model of the Earth's landscape evolution is presented, with ...

Working closely with geologists, he greatly improved our ability to reconstruct past geological events. His high standards of sample collection and lab processing are admired internationally. A ...

Reston, VA – The U.S. Geological Survey (USGS) and the Association of American State Geologists (AASG) announced that they have developed an updated geologic time scale and color scheme for use in ...

Earth’s surface is the “living skin” of our planet—it connects the physical, chemical, and biological systems. Over geological time, landscapes change as this surface evolves, regulating the carbon ...

A thin slice of the ancient rocks collected from Gakkel Ridge near the North Pole, photographed under a microscope and seen under cross-polarized light. Field width ~ 14mm. Analyzing rocks in thin ...

Climate, tectonics and time combine to create powerful forces that craft the face of our planet. Add the gradual sculpting of the Earth’s surface by rivers and what to us seems solid as rock is ...
