Diamonds: Telling the Tale of an Epic Journey

Physics Central reported scientists are using diamonds to support the theory of tectonic plates.

The market news is quoted as saying,

Scientists have known for decades that our planet’s crust — the part we stand on — is formed in mid-ocean ridges. The crustal plates move toward other plates and are eventually forced underneath, or subducted. The subduction explains earthquakes and volcanoes, and where the continents sit. The subducted material slides down toward the center of the earth where it is eventually recycled. No one is quite sure how deep it goes and what happens to it. The diamonds tell the story.

“Diamonds can exist for half the life of the earth,” said Steven B. Shirey of the Carnegie Institution for Science in Washington, in D.C., one of the researchers. “That’s part of their charm.”
