A hunk of stone 100 million years old could be a piece of the real geological lost continent.
A team of geologists have studied earthquakes to find out how they produce gold deposits.
When it comes to creating a picture of the Earth's magnetic history, scientists have pretty good data on the strength and direction of magnetic fields in the Northern Hemisphere, thanks to the study of ancient pottery. But, for researchers looking to make a truly complete model, the problem has been the gaps in information in the southwest Pacific.
Geologists will try and tell you that it's easier to explore the moon and Mars than it is to explore the Earth's mantle. As a geologist myself, I think they're full of it, but they do have a point that we don't know a whole heck of a lot about what's going on beneath our feet. To find out, an international team wants to drill into Earth's mantle, 3.7 miles below the ocean.
The moon may be more or less dead on the inside, but that's not stopping some serious old-school rock 'n' roll from happening on its surface.
Quasicrystals are a weird type of asymmetrical crystalline mineral that was only discovered a few decades ago, and it's only ever been produced in a laboratory under very carefully controlled conditions. At least, that's what we thought, until outer space chucked a meteor full of the stuff right at us.
All it takes to simulate the electromagnetic field of our planet is about 15 tons of liquid sodium in a giant spinning globe. Cool!
55 million years ago, a giant island burst out of the ocean off the northern coast of what is now Scotland. It existed quite happily for a million years or so, and then disappeared, only to be discovered again, now buried a mile beneath the ocean floor.
NASA scientists have discovered a previously unknown type of mineral hiding inside a 4.5 billion year old meteorite. It's a crystalline form of titanium and sulfur, and we've never seen anything like it on Earth.
See this big pile of rocks? It's actually a fully functional nuclear reactor. Or, it was, about two billion years ago.
