What are cratons?
Cratons are the stable interior parts of continents that have not been affected by significant tectonic activity for prolonged periods. They are typically composed of ancient and hard rocks, providing a stable foundation for the continent. Cratons are important for understanding the geological history and evolution of continents.
Why are diamonds only found in certain regions of the world?
Diamonds are typically found in regions with specific geological conditions, such as old volcanic pipes or cratons where the high pressure and temperature necessary for diamond formation can occur. These conditions are not common worldwide, so diamonds are only found in certain areas where these geological processes have taken place.
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 do the sequences of sedimentary rocks in cratons differ from those in mountain belts?
The sequences of sedimentary rocks in cratons are typically thin and are relatively undeformed or gently warped. The sequences in mountain belts, meanwhile, are thick and extensively folded and faulted.
Can craton rift shift apart?
Cratons are stable, rigid blocks of the Earth's crust that are not typically prone to rift or shifting apart. However, under certain tectonic forces or geological processes, cratons can experience minor deformation or fragmentation, resulting in rifts or shifts along their edges. Overall, cratons are known for their stability and strength in the Earth's crust.
What do cratons do?
Cratons contain the ancient crust of igneous rocks.
Where on earth are diamonds normally found?
In old areas of continental crust called "cratons" in volcanic structures called "kimberlite pipes".
What is found in diamonds?
Nothing... diamonds are just one base: carbon.Another AnswerThere are diamonds that contain trace elements that can render colour in the stone. Most diamonds contain at least trace amounts of nitrogen, which gives diamonds a yellow cast: fancy yellow diamonds contain more nitrogen. Boron gives diamonds a blue, or blue-gray cast. And so on.Trace elements that give diamonds colour are not separable from the diamond lattice.
What metals do diamonds have in them?
Diamonds are formed from carbon. Some brown diamonds may contain trace amounts of nickel -- otherwise diamonds do not contain metals.
Does chocolate contain diamonds?
No form of chocolate contains diamonds.
Does jewelry have real diamonds?
Jewelery can contain real diamonds, and jewelery can contain other gems, including stones meant to look like diamonds.
Can diamonds form without kimberlike pipes?
Since diamonds are most rare, indicator minerals are the only way to predict -- sometimes unsuccessfully -- where a miner might locate diamonds.The pipes are always required, since that's how diamonds are pushed up to the surface from earth's upper mantle, and kimberlite is not the only indicator mineral. (Link, below.)Diamond formation does not occur in the pipes: it occurs in cratons. From Wikipedia:"The correct combination of temperature and pressure is only found in the thick, ancient, and stable parts of continental plates where regions of lithosphere known as cratons exist. Long residence in the cratonic lithosphere allows diamond crystals to grow larger."You can read more about cratons, below.

Carbonate minerals contain?
Some minerals contain carbon, such as graphite and diamonds, however while they both contain carbon, the diamonds density is far greater.
What is at least one thing in nature that contains diamonds?
Kimberlite can contain diamonds.
What named carbon do diamonds and coal contain?
Both diamonds and coal contain carbon atoms in their crystal structure. Diamonds have a tetrahedral lattice structure, while coal has an amorphous structure.
What ores do diamond contain?
Diamonds are formed from carbon and contain no ores.
