Diamonds are formed deep within the earth's mantle, under very high temperatures and very high pressures: generally more than 90 miles below the earth's surface, and hotter than 2,000 degrees F. The formation process takes millions of years to complete.
Kimberlite is the igneous rock type that is formed in the same environment as diamonds -- formed from liquid core material.
The incubator for all these formation phenomenon reveals itself in the kimberlite pipes that can contain diamonds -- not all do.
Since kimberlite pipes have been identified by scientists as a phenomenon, none has erupted to the earth's surface.
What else can I help you with?
What geological material are diamonds found in?
Diamonds are typically found in kimberlite pipes, which are vertical volcanic structures that bring diamonds to the Earth's surface. Diamonds can also be found in alluvial deposits, where they have been transported by rivers and streams from their original source.
How do diamonds fit into the rock cycle?
Diamonds are formed deep within the Earth's mantle through high pressure and temperature conditions. They are brought to the surface through volcanic eruptions in rocks called kimberlites. Over time, diamonds can be carried into sedimentary deposits and eventually returned to the Earth's mantle through tectonic processes, completing the rock cycle.
What type of ultramafic rock sometimes contains diamond?
Kimberlites are the rock type that diamonds are usually found in. They are formed when a magma from deep in the mantle drills its way to the surface in a fast gaseous explosive event. Diamonds typically occur as xenocrysts within the Kimberlite matrix. the volcanic deposits are called Lamproite igneous volcanic pipes. Please see the related links.
What natural resource do diamonds come from?
Diamonds come from the Earth's mantle, where high pressure and temperature cause carbon atoms to form the crystal structure of a diamond. These diamonds are brought to the surface through volcanic eruptions in rocks called kimberlites and lamproites.
What is the type of magma that carried most diamonds to the surfaces?
Diamonds are brought to the surface in two main magma types with fairly extreme compositions. These are: Kimberlites and Lamproites. You can read more about them, below. Volcanic pipes that blast diamonds to the earth's surface, also erupt garnet xenoliths onto earth's surface. Only about one in every 200 such pipes contain diamonds. You can read more about the exploratory geology, below.
What type of ultramafic rock contains diamonds?
Diamonds are found in rayer types of igneous rocks known as "Kimberlites"credit to Alberto Vacca
Diamond falls under which category of rocks?
Igneous rocks are the category of rocks that contain diamonds. The two types of igneous rocks that form diamonds are kimberlites and lamproites.
What geological material are diamonds found in?
Diamonds are typically found in kimberlite pipes, which are vertical volcanic structures that bring diamonds to the Earth's surface. Diamonds can also be found in alluvial deposits, where they have been transported by rivers and streams from their original source.
Why do scientists theorize that kimberlites originate deep within the earth crust or mantle?
because diamond and other minerals found in kimberlites can form only under very high pressures
Diamonds are pure form from what element?
Diamonds are the crystaline form of Carbon.

What is the possessive form of the word diamonds?
The possessive form for the plural noun diamonds is diamonds'.Example: I had the diamonds' settings checked by a jeweler.

Do diamonds form from iron?
No, diamonds are formed from carbon.
Do diamonds grows in rocks?
Diamonds are formed deep within the earth's mantle and the rock, kimberlite, is available within the volcanic pipe that erupts these materials to the earth's surface. This may give the impression that diamonds grow in rocks, which is an incorrect impression.
