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.
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.
How many kimberlite pipes are in botswana?
This is impossible to answer with a finite number, because there may be undiscovered Kimberlite pipes in Botswana.
How do kimberlite carry diamonds?
Kimberlite magma originates in the Earth's mantle and can transport diamonds to the surface during explosive volcanic eruptions. These eruptions are fast and violent, creating an environment where diamonds can retain their structure and resist degradation during their journey to the surface within the kimberlite magma.
Does kimberlite react to acid?
Yes, kimberlite does react to acid. The carbonate minerals in kimberlite can fizz or effervesce when they come into contact with acid, indicating a chemical reaction. This reaction is due to the dissolution of the carbonate minerals in the kimberlite by the acid.
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.
How much kimberlite ore does it take to make 1 carat diamond?
Kimberlite is an indicator mineral for diamond, not the genesis of diamond, which is carbon. Individual diamond mines have varying ratios of kimberlite to diamond.
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.
Are kimberlite rocks used for human purpose?
Kimberlite is the main ore of diamonds, but otherwise has little use to humans.
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.
What rock starts with the letter k?
· Kimberlite - a volcanic rock · Kenyte - a volcanic rock found on Mount Kenya
What is the Specific gravity of kimberlite?
The specific gravity of kimberlite typically ranges from 2.25 to 3.3, depending on the composition and density of the minerals present in the rock. This range is due to the varying amounts of minerals like olivine, pyroxene, and garnet found in kimberlite.
Where is kimberlite locations?
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.
Which countries is kimberlite found in?
Australia
