Chapter 787 Run

Blue smoke curled up.

The newly laid planks suffered seedlings like this.

A fist-sized, irregularly shaped black stone was stuck on the board with a dark glow, and in the center, a transparent block at least the size of a thumb shone brightly in the sunlight.

Bi Fang knelt on the platform, bent down, and wanted to punch it with his hands, but when he was close at hand, he was forced back by the heat emitted by it.

The high temperature interacted with the wood, turning the surrounding area into black charcoal gray, and the black hole continued to expand. Then Bi Fang saw the transparent matter in the center of the black stone shrinking at a speed visible to the naked eye!

Before he had time to do any remedial measures, the wooden plank that had been smashed through most of it was directly scalded with a big hole under the high temperature.

With a plop, the stone fell straight into the ocean, followed by a sound similar to that of high-temperature metal colliding with cold water. This sound made his ears callous in the Banna rainforest.

The white bubbles rolled violently, and Bi Fang directly reached out to grab 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 exaggerated. At least there was no hole burned on the wooden board, and the translucent stone on it did not burn.

Bi Fang scooped up some seawater and poured it on the stone to speed up its cooling. When there was no problem, he took it into his hand and placed it in the sun to examine it carefully.

Is this thing a diamond?

The audience couldn't forget the sentence that Bi Fang yelled just now, if it is true, then this star is too big.

Even if it's just a little smaller, it's still half the size of a finger, which is outrageously exaggerated.

And why are diamonds falling from the sky?

[Is this really a diamond? 】

【Why doesn't it look like it?】

[Because it hasn't been cut yet, right? 】

[Purity, too low! 】

[When will Fang Shen come to pinch a diamond with his bare hands]

After looking at it for a while, Bi Fang finally decided that it was really a diamond!

If one survives, there will be future fortunes?

Anyway, let's get a better one.

Bi Fang stroked the diamond which seemed to have many impurities in it, and was speechless.

"Volcanic eruptions do bring some precious metals to the surface, diamonds are mostly carbon, and carbon is not uncommon on Earth."

"The formation of diamonds is different from the high-pressure and low-temperature environment of emerald I mentioned before. It takes place under high-temperature and high-pressure environments. This condition is rare on the earth's surface, but the mantle layer is everywhere, which is very suitable for the formation of diamonds. So many diamonds form in the mantle."

[The volcanic eruption seems to be in the mantle layer? 】

[To be honest, I don't remember these anymore]

[If I were a high school student, I would have to say a few words now, but I am already a senior, and I only know that I eat three meals a day]

"Yes."

Bi Fang 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 5000 ℃, but also the pressure is very high. , so it will press the molten object into a solid."

"Outside the core is the mantle, and above that is a ring of rock, which is the crust."

"Among these substances, the temperature of the lithosphere and the crust is low, while the temperature of the core layer is high, so the mantle layer will form heat convection. The rock ring and crust inside the mantle are affected by heat convection, causing earthquakes, etc. Disasters occur."

"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 limitation of the lithosphere and crust, but where the earth's crust is weak, the mantle material will be erupted to the surface due to the pressure. That's how volcanoes are formed."

"Diamonds are formed in the mantle, and magma is also in the mantle, so after diamonds are formed, they will be brought to the volcanic pipeline along with the magma. When the magma condenses, it will form Kimberlite containing diamonds."

"When a volcano erupts, the matrix containing the diamonds is brought out, and due to the flow of water, the matrix of diamonds breaks up, creating sedimentary sand deposits of diamonds, and most diamond mines have been the site of volcanic eruptions in the past. "

After listening to Fang's explanation and the possible origin of the diamond, the audience was dumbfounded.

[Hiss, quickly tell me the location, I'm going to pick up diamonds now! 】

[Diamonds are just a hype, worthless at all, now we can even artificially produce natural diamonds, not artificial diamonds, but artificially produced "natural diamonds"]

[We all know about this, I have swiped Xiao Li's blood diamond three times]

[One thing to say, to be honest, don't talk so much, just ask if you want to pick it up? 】

[Pick up! Quick report address! I'm crazy! 】

The bullet screens were all asking for the address, while Bi Fang kept looking at it and muttering.

"I didn't expect to be so lucky that I could run into a flying diamond. To be honest, the probability of this is actually very small."

It just happened to hit me so I won’t say anything.

The essence of diamond is carbon, and it will burn directly when it encounters a high temperature of more than 900 degrees. The temperature of magma is usually between 700 and 1200. If it is mixed together, it is easy to burn directly.

If it doesn't mix, it's not in the middle of the eruption, and it can't fly that far.

Unless it happened to be wrapped in rocks and flew out before being fully heated.

In fact, it was almost sublimated just now, but it just happened to burn a hole in the wooden board, and it fell into the sea to accelerate cooling.

The combustion of diamond at high temperature and with oxygen is different from the combustion of carbon. The combustion of carbon is that the whole carbon is burned red, and then the outside is in contact with oxygen and burns.

The burning process of diamond is: no matter how high the temperature is, it is still colorless and transparent, and the external carbon atomic structure slowly disappears when exposed to oxygen.

As a consequence of heating in the absence of oxygen: the already unstable diamond structure transforms into graphite.

So the diamond may have been bigger at first and not completely encased in stone, or it would be a piece of graphite now.

It’s just that the size of the diamond is big. After burning some, it still has the size of the first knuckle of a little finger. However, the color is not very good, the clarity is quite bad, and it is full of impurities. At first glance, you don’t even think it’s a diamond, but a diamond. Stone with high transparency.

In fact, the degree of value is relatively limited. It's not bad as a collectible, but it can't be sold at a high price.

[One thing to say, this is the first time I have heard that volcanoes will erupt diamonds]

[Why I'm not so lucky]

[Come to a volcano surfing, if you survive, you can too! 】

[Bring my surfboard, let's go! 】

Gray snow fell from the sky.

The surface of the sea was covered with a thin layer of gray mist, as if a layer of lime had been sprinkled on the clean water.

Regardless of the audience's teasing and incitement to return to pick up diamonds, Bi Fang pulled the sails, picked up the oars and headed in the opposite direction.

He is not Contra, he does not have three lives.
