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.
Do all volcanoes have kimberlite?
No. Most volcanoes do not have kilberlite. Kimberlite is a rather unusual form of igneous rock found primarily in kimberlite pipes.
How do trucks get to the bottom of a kimberlite pipe?
Kimberlite pipes are typically quarried using open pit mines.
Why are diamonds most commonly found in Africa?
Diamonds are brought to the surface from the lower mantle by means of kimberlite pipes. Kimberlite pipes are only found within old cratonic crust, such as Africa.
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.

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.
Do all volcanoes have kimberlite?
No. Most volcanoes do not have kilberlite. Kimberlite is a rather unusual form of igneous rock found primarily in kimberlite pipes.
How do trucks get to the bottom of a kimberlite pipe?
Kimberlite pipes are typically quarried using open pit mines.
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.
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.

Is kimberlite intrusive or extrusive?
They are Intrusive forming unique vertical pipes in the earth's crust.
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.
How do kimberlite carry diamonds?
Kimberlite pipes, the best source of mined diamonds today, erupt to the earth's surface like any volcano. You can read more about this morphology and volcanology, below.
