Are kimberlite lamproite and serpentinite volcanic pipes common in California?
There are no known kimberlite or lamproite volcanic pipes in California. There are many serpentinite bodies present, but these are generally not volcanic pipes and are not of deep seated origin.
Where do diamonds erupt to the surface?
Diamonds erupt to the surface through volcanic pipes called kimberlite pipes. These pipes are formed deep in the Earth's mantle and bring diamonds closer to the surface during volcanic eruptions. Once on the surface, the diamonds can be found in countries like South Africa, Botswana, Russia, and Canada.
What is a craton and what is a kimberlite pipe and how are they linked to the discovery of the diamond?
A craton is 'an old and stable part of the lithosphere' -- the earth's crust. One class of inclusions in the formation of the earth's crust when subductions of crust were folded into the deep, kimberlite diamond areas that lie about 150-450 K below the surface. Diamonds as we know them are exploded to the earth's surface through kimberlite pipes, which are carrot shaped and widest at the surface. Although not all kimberlite pipes are sources for diamonds, most diamonds are found in areas where kimberlite pipes occur.
Do all volcanoes have kimberlite?
No, not all volcanoes have kimberlite. Kimberlite is a type of volcanic rock that often contains diamonds, but it is only found in specific geological settings. Other types of volcanoes can be composed of different types of magma and erupt different types of rocks.
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.
Where are the world's most kimberlite pipes?
South Africa has the most kimberlite pipes. The link below has more inforamtion you might be interested in.
Where can you find kimberlite rock?
in kimberlite pipes. these happen in many parts of the world (including the U.S.) but they seem to be most concentrated in southern africa.
Are kimberlite lamproite and serpentinite volcanic pipes common in California?
There are no known kimberlite or lamproite volcanic pipes in California. There are many serpentinite bodies present, but these are generally not volcanic pipes and are not of deep seated origin.
Where can I find a map of kimberlite pipes in the USA?
You can find a map of kimberlite pipes in the USA through geological surveys or research institutions that specialize in diamond exploration and mining. These organizations may have publicly available maps or data on kimberlite pipe locations.
Where can you find Raw diamonds?
In 'kimberlite pipes' which are volcanic vents deep underground in South Africa, Brazil, Canada, Australia and India. Also in river sediments the flow over these pipes, and kimberlite pipes in other parts of Africa.
Where is a diamond mostly found?
Diamonds are mostly found in kimberlite pipes, which are vertical shafts formed by ancient volcanic eruptions. They are also found in alluvial deposits, which are sedimentary deposits of eroded material from the kimberlite pipes. Diamond mining is concentrated in countries like South Africa, Russia, Botswana, Canada, and Australia.
What countries can kimberlite be found in?
Kimberlite can be found in various countries around the world, including South Africa, Russia, Canada, Australia, and Botswana. These countries are known for their diamond mining operations that are associated with kimberlite deposits.
Where do diamonds erupt to the surface?

Where can I find a detailed kimberlite pipes map for diamond exploration purposes?
You can find detailed kimberlite pipes maps for diamond exploration purposes from geological surveys, mining companies, and academic research institutions specializing in diamond exploration. These maps typically show the locations of known kimberlite pipes, which are the primary source of diamonds, and can help guide exploration efforts.
Is kimberlite intrusive or extrusive?
They are Intrusive forming unique vertical pipes in the earth's crust.
How do kimberlite pipes and diamonds form?
Kimberlite pipes form when magma rises from deep within the Earth's mantle and rapidly reaches the surface, carrying diamonds and other minerals with it. The extreme pressure and temperature inside the mantle crystalize carbon atoms into diamonds within the kimberlite magma. When the kimberlite erupts onto the surface, it brings diamonds along, creating diamond deposits.
