Natural nanodiamonds in oceanic rocks

Natural diamonds can form through low pressure and temperature geological processes on Earth, as stated in an article published in the journal Geochemical Perspectives Letters. The newfound mechanism, far from the classic ...

New insights into the formation of Earth's crust

New research from Mauricio Ibanez-Mejia, an assistant professor of Earth and environmental sciences at the University of Rochester, and Francois Tissot, an assistant professor of geochemistry at the California Institute of ...

Plankton as a climate driver instead of the sun?

Fluctuations in the orbital parameters of the Earth are considered to be the trigger for long-term climatic fluctuations such as ice ages. This includes the variation of the inclination angle of the Earth's axis with a cycle ...

Tibetan plateau rose later than we thought

The Tibetan Plateau today is on average 4,500 meters above sea level. It is the biggest mountain-building zone on Earth. Most analyses to date indicated that, back in the Eocene period some 40 million years ago, the plateau ...

Understanding the glacial history of the western Arctic

To interpret what we see today both on land and at the seabed, we need to understand how the landscape was different in the past. When we say "past," we mean on a geologic timeframe—specifically, about 10,000 to 20,000 ...

The worms that changed the world

In the shallow waters of a sea in northern China 500 million years ago, a dazzling new array of creatures was swimming: part of an explosion of animal diversity that would forever change the course of life on Earth.
