Diamonds ascend to the Earth's surface in rare molten rock, or magma that originates at great depths. Carrying diamonds and other samples from Earth's mantle, this magma rises and erupts in small but violent volcanoes.
Just beneath such volcanoes is a carrot-shaped "pipe" filled with volcanic rock, mantle fragments, and some embedded diamonds. The rock is called kimberlite after the city of Kimberley, South Africa, where the pipes were first discovered in the 1870s.
Another rock that provides diamonds is lamproite.
The extraction process can take place at the mine site, where the excavated material is washed and tumbled. Because diamond is heaviest of all the materials mined, it falls to the bottom and is otherwise sorted from the mined materials.
What else can I help you with?
Are most most diamonds formed inside kimberlite?
All diamonds are formed from carbon. Kimberlite and diamonds are both erupted to the earth's surface via volcanic pipes. Kimberlite is an indicator mineral, increasing odds for geologists that a volcanic pipe includes diamonds: not all pipes erupt diamonds with kimberlite. Kimberlite can be considered a 'neighbor' or 'kin' of diamond, but not a source.
What is Kimberlite Magma?
Kimberlite magma is a rare type of volcanic rock that is known for containing diamonds. It is derived from the Earth's mantle and is typically generated during deep-source volcanic eruptions. Kimberlite deposits are important for diamond mining, as they carry diamonds to the surface from deep within the Earth.
Are most diamonds mined directly from Kimberlite?
Kimberlite is an indicator mineral, formed deep within the earth's mantle where diamonds are also formed. Often, they are found together, but not always. Kimberlite is not diamond: they are different minerals.
What rocks have diamonds inside of them?
Diamonds are found in kimberlite and lamproite rocks, which are formed deep within the Earth's mantle and brought to the surface through volcanic activity. These rocks can sometimes contain diamonds as inclusions or as separate crystals.
Where is kimberlite found?
Kimberlite is typically found in regions with ancient volcanic activity, such as cratons and continental lithosphere. Some common locations include southern Africa, Canada, Australia, and Russia. These regions have preserved the deep mantle source rocks that give rise to kimberlite.
Which valuable mineral is often found in the rock called kimberlite?
The valuable mineral often found in kimberlite is diamond. Kimberlite is an igneous rock that forms deep within the Earth's mantle and is known for transporting diamonds to the surface during volcanic eruptions. Diamonds extracted from kimberlite deposits are highly sought after for their beauty and industrial applications.
How is diamond extracted from the ground?
Raw diamonds are mined from the earth around kimberlite pipes that erupt this material to the earth's surface.
African diamonds are contained in what?
All diamonds are erupted to the earth surface together with indicator minerals, including kimberlite. Other minerals are present in fertile kimberlite -- containing diamonds -- and absent in sterile kimberlite.
Why are diamonds found in kimberlite rock?
Apparently kimberlite pipes -- that can contain diamonds -- are volcanic formations that begin deep within the earth's mantle. Because diamonds and kimberlite -- and other semi-precious gems -- are formed in similar locations, some kimberlite rock contains diamonds. You can read more, below.
Are most most diamonds formed inside kimberlite?
All diamonds are formed from carbon. Kimberlite and diamonds are both erupted to the earth's surface via volcanic pipes. Kimberlite is an indicator mineral, increasing odds for geologists that a volcanic pipe includes diamonds: not all pipes erupt diamonds with kimberlite. Kimberlite can be considered a 'neighbor' or 'kin' of diamond, but not a source.
What is at least one thing in nature that contains diamonds?
Kimberlite can contain diamonds.
When diamonds are in the ground what is the rock around it?
Some diamonds may be included in kimberlite.
Why kimberlite might be found in diamonds?
Kimberlite is the natural structure within which diamonds are found (kimberlite "pipe"). A Kimberlite pipe is the normal underground site(s) of a diamond bearing geologic formation.Another AnswerKimberlite is a mineral, called a trace mineral, because in one out of 200 cases, when kimberlite is found, diamonds are also found. Why? Because the geological processes required to form diamonds also forms kimberlite, which is a 'potassic volcanic rock' according to Wikipedia.
What is the name for igneous rock that contains diamonds?
kimberlite
Are kimberlite rocks used for human purpose?
Kimberlite is the main ore of diamonds, but otherwise has little use to humans.
What mineral do diamonds come from?
Diamonds are made from carbon, which is an element. They are made within "kimberlite" rock - I do not know if kimberlite is a mineral, or not. Sometimes, diamonds are washed out of kimberlite by the weather, and can be found in placer (PLASS-uhr) deposits, that is, at or near the surface of the ground. There are also diamonds found in meteorites that fell to Earth perhaps 3.5 billion years ago.
Why haven't there been reports of diamonds in kimberlite pipe rocks?
Diamonds are found as loose stones, or can be embedded in other materials, including kimberlite. See the linked photo, below.
