There's a billion-year gap in Earth's geological history. A new study seeks to explain the mystery.

A layer of rock just 520 million years old sat directly on top of ancient rock dating back 1.4 to 1.8 billion years.

Researchers have made a new discovery that changes our understanding of Earth's early geological history, challenging beliefs about how our continents formed and when plate tectonics began. A study ...

New research sheds light on the earliest days of the earth's formation and potentially calls into question some earlier assumptions in planetary science about the early years of rocky planets.

The history of Earth's continents might be different from what we first thought. The most popular theory of how the continents formed billions of years ago may not be right, according to a paper in ...

Earth history, as a scientific topic, encompasses the reconstruction and analysis of the planet’s physical, chemical, and biological evolution from its formation ~4.54 billion years ago to the present ...

About 4.5 billion years ago, the most momentous event in the history of Earth occurred: a huge celestial body called Theia collided with the young Earth. How the collision unfolded and what exactly ...

The solar system formed about 4.6 billion years ago from a condensed nebula, and with it our planet Earth, which was a ball ...

Modern continental rocks carry chemical signatures from the very start of our planet's history, challenging current theories about plate tectonics. Researchers have made a new discovery that changes ...
