Kimberlite pipes are typically quarried using open pit mines.
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.
No. Most volcanoes do not have kilberlite. Kimberlite is a rather unusual form of igneous rock found primarily in kimberlite pipes.
Nonoxizied Kimberlite is called Blue Ground, due to the blue color..Oxizdized Kimberlite is called Yellow ground due to the yellow color. It is a deep Tawny Yellow.
This is impossible to answer with a finite number, because there may be undiscovered Kimberlite pipes in Botswana.
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.
Visually, there are trace minerals that indicate a volcanic pipe, which might contain diamonds. The trace minerals include kimberlite, and only one kimberlite pipe in 200 yields gem-quality diamonds. You can read more, below.
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.
Diamonds are found as loose stones, or can be embedded in other materials, including kimberlite. See the linked photo, below.
potassic volcanic rock best known for sometimes containing diamonds
Kimberlite is a volcanic rock that is commonly associated with the formation of diamonds. It is formed deep within the Earth's mantle and is brought to the surface through volcanic activity. Kimberlite magma is rich in carbon, which is necessary for diamond formation. As the magma rises to the surface, it cools and solidifies, capturing and preserving the diamonds that formed within it.
Natural diamonds from the Earth originate in kimberlite pipes, and can be swept away by water or glaciers. This means that some diamonds are found in river beds and at the mouths of rivers as they empty into salt water.

Diamonds are generally found near kimberlite and other trace minerals that indicate a volcanic pipe where diamonds have erupted to the earth's surface.
Yes. Kimberlite will dissolve in acid.
Kimberlite rocks are typically found in regions with ancient cratons, such as Africa, Canada, Russia, and Australia. These rocks are known for their diamond-bearing potential and are often associated with volcanic activity. Mining companies often search for kimberlite deposits as they can indicate the presence of diamonds.
Not quite. The invert elevation of a pipe is measured at the flow line which is the bottom inside of the pipe. The bottom of pipe elevation should be the bottom outside of the pipe. The difference betwen the two measurements is the thickness of the pipe wall.
