下载Rocks and minerals are known for being tough.
They’re the hard stuff that makes up the planet, and without them…well, we wouldn’t have much of a planet at all.
Lots of the minerals on Earth started out life as liquids, either dissolved in water or heated above their melting point.
But occasionally, the minerals can form in such a way that preserves a few drops of fluid inside of them.
This primeval liquid isn’t likely to replace your water bottle any time soon, but it is more than just a curiosity.
It’s a window into the workings of the ancient Earth.
So let’s talk about the forbidden mineral water in these crystals, and why you should not drink it.
[♪ INTRO]
The majority of minerals on our planet crystallize from fluids beneath the Earth’s surface, and this crystallisation happens when the pressure, temperature, or saturation of the liquid reaches the Goldilocks point for mineral formation.
And that perfect combo of temperature and pressure is different for each mineral.
For instance, igneous minerals freeze out of molten lava when the temperature dips below their melting point.
Meanwhile, sedimentary minerals crystallize when the concentrations of their component molecules gets high enough.
Crystals can begin to grow in a lattice within that fluid, building up a scaffold of atoms and bonds.
But if there’s anything else floating around inside that fluid, it can interfere with the growing crystal, and cause imperfections in the 3D lattice.
