The causes of diamond production
Diamond is commonly known as "diamond". That is to say, the original body of diamond, which is a kind of mineral composed of carbon element and an allotrope of carbon element. Diamond is a hard substance in nature. Diamond has a wide range of uses, such as crafts, cutting tools in industry. Graphite can form synthetic diamond at high temperature and high pressure. It's also a precious gem.
The primary diamond is crystallized at high temperature (900-1300 ℃) and high pressure (45-60) & 215; 108pa (130-180km) deep underground. They are mainly stored in kimberlite or K-Mg lamprophyre, and their formation age is quite long.
The origin of Kimberley rock diamond, such as South Africa Kimberley ore, dates back to 3 billion 300 million years ago. It is almost the same age as the earth. It is 1 billion 580 million years and 990 million years ago that the source of the potassium magnesium magnesia type diamond, such as the Australian Argyll mine and the Botswana olive deposit, is young. If the diamond crystal hidden in such a large underground depth for hundreds of millions of years can be seen again, it must help volcano eruption, lava flow will bring the magma containing diamonds to the earth near the surface, or long-distance migration and sedimentation in the river sand. The former formed primary tubular ore, while the latter formed alluvial ore. Another kind of diamond is produced in outer space. The impact of space on "nano diamond" is also a pure single "carbon single substance" characteristic.
If any two different minerals are characterized with each other, one of them will be damaged. There is a mineral that can scratch all other minerals, but no mineral can scratch it. This is diamond. From this we can see that diamond is very hard and is a good material for use.
