The Volcano That Erupts Diamonds

Diamonds are associated with a very strange and rare type of volcanic eruption. Volcanic pipes, aren't all that uncommon. What is, though, is the variant of them, which sources magma from close to 700km deep within the Earth. What this means, is this magma, passes through a transition zone known as the Diamond stability field. And as a result of this, it's able to bring diamonds up to the surface when it erupts.Show more

But it's not only this that makes Kimberlite so strange. It's also the fact that the type of magma that kimberlite is comprised of, is known as ultra-mafic. Mafic magma, is known for being relatively non-explosive and more effusive in the way it erupts. This is because of the very low silica levels that Mafic magma inhabits. As you can probably imagine, ultra-mafic magma contains even less silica. Yet, it's able to explode up from depths of over 600 kilometers and surface in a matter of hours.

Kimberlite eruptions also have no magma chamber. They literally just push their way to the surface, at a tremendous speed, propelled forth by a strange chemistry from deep within the Earth, only to surface is an extremely explosive manner. Thankfully, these eruptions aren't anything close to what one would witness with a supervolcanic eruption. They don't affect the entire Earth, but if one happened near you... trust me, you'd know about it.
