Chapter 784 Run

Green smoke is curling up.
The newly laid wooden boards were damaged like this.
A fist-sized, irregularly shaped black stone with a dim glow was stuck on the wooden board. In the center of the stone, a transparent object at least the size of a thumb was gleaming in the sunlight.
Bifang knelt on the platform, leaned down, and tried to grab it with his hands, but when he was close to it, he was forced back by the heat it emitted.
Due to the interaction between the high temperature and the wooden board, the surrounding area turned into charcoal gray, and the black hole was still expanding. Then Bifang saw that the transparent substance in the center of the black stone was shrinking at a speed visible to the naked eye!
Before any remedial measures could be taken, a large hole was burned into the wooden board, which had already been mostly broken through, due to the high temperature.
With a splash, the stone fell straight into the ocean, followed by a sound similar to that of hot metal colliding with cold water. Bifang's ears were callused from hearing this sound in the Xishuangbanna rain forest.
The white bubbles rolled violently, and Bifang reached out and grabbed the sinking stone, quickly picked it up and threw it on the wooden board.
The remaining water stains evaporated quickly, but the temperature of the stone was no longer so extreme. At least it did not burn a hole in the wooden board, and the translucent stone on top was gone.
Bifang scooped some sea water and poured it on the stone to speed up its cooling. After it was okay, he took it in his hand and examined it carefully in the sun.
Is this thing... a diamond?
The audience couldn't forget the words Bifang had just shouted. If it was true, then this one was too big.
Even though it has just shrunk a bit, it is still as big as half a finger, which is ridiculously exaggerated.
And why do diamonds fall from the sky?
[Is this thing really a diamond? ]
[Why doesn’t it look like that?]
[Because it hasn't been cut yet? ]
[Purity is too low! ]
[When will Fang Shen show me how to pinch a diamond with his bare hands?]
Bifang looked at it for a long time and finally confirmed that it was actually a diamond!
Will there be good fortune in the future if you survive a great disaster?
At least get one with higher quality.
Bifang was speechless as he stroked the diamond that seemed to have many impurities in it.
"Volcanic eruptions do bring some precious metals to the surface, and diamonds are mainly composed of carbon, which is not uncommon on Earth."
"The formation of diamonds is different from the high pressure and low temperature of jade that I mentioned earlier. It takes place under high temperature and high pressure. Such conditions are rare on the surface of the earth, but they are everywhere in the mantle layer, which is very suitable for the formation of diamonds. Therefore, many diamonds are formed in the mantle layer."
[It seems that volcanic eruptions occur in the mantle layer? 】
[To be honest, I don’t remember this anymore]
[If I were a high school student, I would have to say something about this now, but I’m already a senior and I only know how to eat three meals a day]
"Yes."
Bifang nodded.
"The formation of craters is related to the structure of the earth. According to our current understanding of the earth, the earth is like an onion, with several layers inside. The core is the core. The temperature of the core is not only above 5,000 degrees Celsius, but also very high pressure, so it will compress molten objects into solids."
"Outside the core is the mantle, and above that is a ring of rock, and the rock is the crust."
"Among these materials, the temperature of the lithosphere and crust is lower, while the temperature of the core layer is higher, so thermal convection will form in the mantle layer. The rock ring and crust inside the mantle are affected by thermal convection, leading to disasters such as earthquakes."
"In addition to the extremely high temperature, the pressure of the mantle material is also relatively high. Generally, it is difficult for the mantle material to break through the restrictions of the lithosphere and crust. However, in places where the crust is weak, the mantle material will erupt to the surface due to the pressure. This is how volcanic eruptions are formed."
"Diamonds are formed in the mantle, and magma is also in the mantle, so after diamonds are formed, they are carried into the volcanic pipe with the magma. When the magma condenses, kimberlite containing diamonds is formed."
"When a volcano erupts, the host rock containing diamonds will be brought out, and due to the action of water flow, the host rock of diamonds will be broken up, thus forming the sedimentary placer of diamonds. Most diamond mines were once the site of volcanic eruptions."
After hearing Fang’s explanation and the possible origin of the diamond , the audience was stunned.
[Hiss, tell me the location quickly, I want to pick up diamonds now! ]
[Diamonds are just a hype and are not worth anything at all. Now we can even artificially create natural diamonds. They are not artificial diamonds, but artificially created "natural diamonds"]
[We all know about this. I have used Brother Li’s blood diamond three times.]
[Let's be honest, don't talk too much, I just want to ask you whether you will pick it up or not? 】
[Pick it up! Report the address quickly! I’m picking it up like crazy! ]
The comments were all asking for the address, while Bifang kept staring at it and muttering to himself.
"I didn't expect to be so lucky that I could actually encounter a flying diamond. To be honest, the probability of this happening is actually very small..."
I won't say anything because it just happened to hit me.
Diamonds are essentially carbon, and they will burn directly when exposed to temperatures over 900 degrees. The temperature of magma is usually between 700 and 1200. If the two are mixed together, they will be easily burned directly.
If it doesn't mix, it won't be in the center of the eruption and won't be able to fly that far.
Unless it happens to be wrapped in rock and flies out before it is thoroughly heated.
In fact, it almost sublimated just now, but it just burned a hole in the wooden board, and fell into the sea, cooling down faster.
The combustion of diamonds in high temperature and in the presence of oxygen is different from that of carbon. The combustion of carbon is that the entire carbon is burned red, and then the outside comes into contact with oxygen and burns.
The burning process of diamond is: no matter how high the temperature is, it remains colorless and transparent, and the external carbon atomic structure slowly disappears when it comes into contact with oxygen.
As for the result of heating in the absence of oxygen, the inherently unstable diamond structure transforms into graphite.
So the diamond may have been larger initially and not completely encased in stone, otherwise it would have become a piece of graphite by now.
The diamond is big, and after some burning it is still the size of the first joint of the little finger, but the quality is not very good, the clarity is quite bad, and it is full of impurities. At first glance, you won’t even think it is a diamond, but a stone with relatively high transparency.
The value is actually quite limited. It's good as a collectible, but it can't be sold at a high price.
[To be honest, this is the first time I’ve heard of a volcano spewing diamonds]
Why I don’t have such good luck
【Come on a volcano surfing trip, if you survive, you can do it too! 】
【Take my surfboard and go! 】
Gray snow fell from the sky.
There was a thin layer of gray fog on the sea, as if a layer of lime had been sprinkled on the clean water.
Bifang ignored the audience's teasing and urging to go back and pick up the diamonds, pulled the sail, picked up the oars and headed in the opposite direction.
He is not Contra and does not have three lives.
