Los Angeles may be a city obsessed with youth, but it is also home to the world’s largest collection of Hadean zircons — the oldest known material on Earth. Hadean zircons are tiny — about the same ...

Conditions on Earth during its first 500 million years may have been cool enough to form oceans of water instead of being too hot for life to form. This alternate view of Earth's first geologic eon, ...

Knowing when the geodynamo started is important for understanding the evolution of the core, the atmosphere, and life on Earth. We report full-vector paleointensity measurements of Archean to Hadean ...

The oldest known material on Earth is a tiny bit of zircon crystal that has remained intact for an incredible 4.4 billion years, a study confirms. The ancient remnant of the early Earth may change the ...

There are many open questions about how our planet formed 4.55 billion years ago: When did plate tectonics start? When did the Earth's mantle begin to vigorously circulate in a process called ...

A handful of ancient zircon crystals found in South Africa hold the oldest evidence of subduction, a key element of plate tectonics, according to a new study published today in AGU Advances. These ...

Scientists used to think that when Earth first formed, it was an uninhabitable wasteland, covered with molten lava and without a solid crust or ocean. They thought it was, literally, Hell on Earth.

Although zircon crystals from Jack Hills, Australia are some of the oldest minerals on Earth, dating to the early Hadean Eon, researchers report that magnetite within the zircons, which could preserve ...

Conditions on Earth for the first 500 million years after it formed may have been surprisingly similar to the present day, complete with oceans, continents and active crustal plates. This alternate ...
