Did you know: scientists have discovered a vast reservoir of water trapped within the Earth's mantle?
scientists have discovered a vast reservoir of water trapped within the Earth's mantle, specifically within the mineral ringwoodite. This water is not in liquid form, but rather locked within the crystal structure of ringwoodite, a mineral found in the Earth's mantle transition zone, roughly 400 miles beneath the surface. This discovery suggests that the Earth's mantle may contain as much water as all the surface oceans combined. Here's a more detailed explanation: Ringwoodite: This mineral is a high-pressure form of olivine and is found in the Earth's mantle transition zone, which lies between the upper and lower mantle. Water Storage: Ringwoodite can trap water within its crystal structure, effectively acting like a sponge. Location: The water is located about 400 miles below the Earth's surface. Quantity: The amount of water in the mantle is estimated to be three times the volume of all the Earth's surface oceans. Implications: This discovery has significant implications for our understanding of Earth's water cycle, mantle dynamics, and the potential for water to play a role in volcanic activity. How it was found: Scientists used seismic wave data from earthquakes to map the Earth's interior and discovered that the waves slowed down when passing through the region containing ringwoodite, indicating the presence of water
We used Forsterite, a relative of the material, for spacer rings at Seagate in our disk formatting process that I named MDW. We noticed that if the rings got below freezing they could crack and water droplets were visible in the break so they had to be shipped at ambient temperature and pressure.
Ringwoodite and Forsterite are not the same thing, although they are closely related. Here's why: Polymorphs: Ringwoodite and Forsterite are polymorphs, meaning they have the same chemical formula (Mg₂SiO₄) but different crystal structures. Crystal Structure: Forsterite crystallizes in the orthorhombic system, while Ringwoodite has a spinel structure and crystallizes in the isometric system. Formation Conditions: Ringwoodite is a high-pressure polymorph of forsterite, stable in the Earth's upper mantle at depths of 520 to 660 km. Forsterite, on the other hand, is the magnesium-rich end-member of the olivine solid solution series and is most abundant in the upper mantle above 410 km. Density: The density of Ringwoodite is about 10% higher than that of forsterite. This higher density is a primary reason for its stability at higher pressures. In summary, while they share the same chemical formula, Ringwoodite and Forsterite are distinct minerals with different crystal structures and formation conditions, primarily found in different regions of the Earth's mantle.
The forsterite parts we got from Kyocera was made in the lab.
I already knew that. But you’re forgetting about how the nazis escaped down there and use living dinosaurs to build their fortresses. They eventually plan to retake the surface world.
