Subduction The movement downward and sideways of a plate of the earths crust beneath another plate is called subduction.
How do diamonds form. Inclusions used for dating are around 100 microns in diameter 01 mm. Between 100 km and 200 km. The critical temperature-pressure balance required for carbon to form diamonds is not present worldwide.
While coal forms from the decay of plant matter and the subsequent burial and solidification of leftover carbon the most common way diamonds are formed is through eruptions shooting upward from the mantle in vertical kimberlite pipes. If playback doesnt begin shortly try restarting your device. Diamonds have been coveted for thousands of years.

Diamonds occur naturally in the earths mantle 150 kms below the surface and require extremely high temperature and pressure. Contrary to popular belief diamonds do not come from coal although they may be similar in chemical composition. Diamonds are formed deep within the Earth.
You see when diamonds are formed under extreme temperature and pressure atoms in their crystalline structure become tetrahedrally bonded each carbon atom links to 3 other carbon atoms to create a strong and stable lattice. The idea that diamonds take millions of years to form is an assumption based on a naturalistic worldview that assumes slow and gradual processes. They are the hardest natural substance and one of the most precious stones.
Diamonds begin to form when these conditions are met. Diamonds Are Formed in the Earths Mantle. They bond together to start growing crystals.
Lab-made diamonds are often called synthetic but that doesnt mean theyre fake. They just didnt come from the. Diamond is a metasomatic mineral that forms during migration of carbon-bearing fluids which means that it forms from fluids and melts that move through the mantle.
In fact there is evidence that diamonds have been collected and traded in India as early as the fourth ce. The diamond crystallizes and matures within six to 10 weeks. The diamond is then polished and graded.
Where do diamonds come from. Videos you watch may be added to the TVs watch history and influence TV recommendations. Only works for very young carbon.
But theres great evidence that diamonds are actually young. The secret of how diamonds are made. Diamond formation could occur this way as little as 50 miles below the surface at a temperature as low as 390 degrees Fahrenheit.
When growing diamonds in a lab technicians place acid into a heat and pressure chamber replicating the natural growth process. Discover how they are made and much more in our infographic. How Are Diamonds Formed by Deep Source Volcanic Eruptions.
You need to use other radioactive decay schemes eg uranium-lead to date inclusions in diamonds.
