WASHINGTON (Reuters) - To put it mildly, this is one gem of a gem. Scientists using two different age-determining techniques have shown that a tiny zircon crystal found on a sheep ranch in western ...

Ever heard this life advice? When solving a big problem seems impossible, break it into smaller steps. Well, scientists just took one of geology's biggest controversies and shrunk it down to atomic ...

A sample of rough zircon crystal on a white marble background from Khibiny, Kola Peninsula, Russia. It is humbling to think that the history of our planet can be locked inside something so small. The ...

The Earth is really old - about 4 1/2 billion years old. And when scientists want to learn about its earliest history, they turn to a mineral that serves as an almost perfect geologic clock. As part ...

Zircons studied by the research team, photographed using cathodoluminescence, a technique that allowed the team to visualize the interiors of the crystals using a specialized scanning electron ...

Scientists have confirmed that a tiny zircon crystal is the oldest piece of the Earth's crust, at 4.4 billion years old. The crystal was discovered on a sheep ranch in Perth, Australia in 2001, but ...

Anyone have extra birthday candles on hand? Because NASA’s about 40 million short. A new and in-depth atomic analysis of an Apollo-era Moon rock — a hunk of hardened magma and zircon crystal collected ...

A 4.4 billion-year-old zircon crystal is providing new insight into how the early Earth cooled from a ball of magma and formed continents just 160 million years after the formation of our solar system ...

The oldest known Earth stuff that remains on the surface of our planet is a mineral that's been called the "Time Lord" because it's so incredibly good at keeping geologic time. The mineral is zircon, ...
