Chapter 784 Run

Blue smoke bird.

The newly-laid planks were slaughtered like this.

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

Bi Fang knelt on the platform, leaned down, and tried to buckle, but when he was close to Chi Chi, he was forced back by the heat radiating from it.

The high temperature interacted with the wooden board, and the surrounding area became black carbon ash, and the black hole was still expanding. Then Bi Fang saw that the transparent material in the center of the black stone was shrinking at a speed visible to the naked eye!

Before there was time to do any remedial measures, the plank that had been smashed through most of it was burnt out of a large hole under the high temperature.

With a thud, the stone fell straight into the ocean, followed by a sound similar to that of high-temperature metal hitting cold water. This sound made Bi Fang’s ears cocooned in the Banna rainforest.

The white bubbles tumbled violently, and Bi Fang directly reached out and dragged the sinking stone, picked it up quickly, and threw it on the board.

The remaining water stains evaporated quickly, but the temperature of the stone is no longer so exaggerated, at least there is no more hole burned on the wooden board, and the translucent stone above is not in the heat.

Bi Fang scooped up some sea water and poured it on the stones to speed up their cooling. When there was no problem, he took them and put them in the sun to examine them carefully.

Is this thing… a diamond?

The audience was obsessed with the words that Bi Fang had just shouted, without him, if it is true, then this one is too big.

Even if it was just a small circle, it was the size of half a finger, which was ridiculously exaggerated.

And why do diamonds fall from the sky?

[This thing is 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 squeeze a diamond with his bare hands]

Bi Fang watched for a while, and finally determined that this was actually a diamond!

If one survives, there will be future fortunes?

Anyway, come to a higher quality.

Bi Fang was speechless as he rubbed the diamond which seemed to have many impurities in it.

“Volcanic eruptions do bring some precious metals to the surface, and diamonds are mostly 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 before. It is carried out in a high temperature and high pressure environment. This condition is rare on the earth’s surface, but the mantle layer is everywhere, which is in line with the formation conditions of diamonds. So many diamonds form in the mantle layer.”

[The volcanic eruption seems to be 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 a few words now, but I am already a senior and only know to eat three meals a day]

“Yes.”

Bi Fang nodded.

“The formation of craters is related to the structure of the earth. According to what we know about the earth, the earth is like an onion with several layers in it. The core is the core. The temperature of the core is not only above 5000℃, but also the pressure is very high. , so the molten object is pressed into a solid.”

“Outside the core is the mantle, and above it is a ring of rock, and the rock is the crust.”

“Among these materials, the temperature of the lithosphere and the crust is lower, while the temperature of the core layer is higher, so the mantle layer will form thermal convection. The rock ring and crust inside the mantle are affected by heat convection, causing earthquakes, etc. disaster occurs.”

“In addition to the extremely high temperature, the pressure of the material in the mantle layer is also relatively large. Generally, it is difficult for the material in the mantle layer to break through the limitations of the lithosphere and crust, but where the crust is weak, the material in the mantle layer will erupt to the surface due to the action of pressure. That’s how volcanic eruptions are formed.”

“Diamonds are formed in the mantle, and magma is also in the mantle, so after the diamonds are formed, they will be brought into the volcanic pipeline with the magma. When the magma condenses, kimberlites containing diamonds are formed.”

“When a volcano erupts, the parent rock containing the diamonds is brought out, and the parent rock of the diamonds is broken due to the action of the water flow, creating the sedimentary sand deposits of diamonds, most of which have been the site of eruptions in the past. ”

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

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

[Diamonds are just a hype, they are worthless at all, and now we can even make natural diamonds artificially, not artificial diamonds, but artificial “natural diamonds”]

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

[One thing to say, come on, don’t talk too much, just ask if you pick it up? 】

【Pick up! Quick address! I’m picking it up! 】

The barrage was all asking for the address, but Bi Fang kept looking at it and murmured.

“I didn’t expect that luck would be so good, to be able to encounter a flying diamond. To be honest, the probability of this is actually very small…”

Just smashed over and didn’t say it.

The essence of diamond is carbon, and it will burn directly when it encounters a high temperature of more than nine hundred degrees.

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

Unless it happened to be wrapped in rock and flew out before it was thoroughly heated.

In fact, it almost sublimated just now, but it happened to burn a hole in the wooden board, and it was cooled down quickly when dropped into the sea.

When diamonds are at high temperature and there is oxygen, it is different from the combustion of carbon. The combustion of carbon is that the entire carbon is burned red, and then the outside is burned in contact with oxygen.

The combustion 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 for the result of heating in the absence of oxygen: the already unstable diamond structure is transformed into graphite.

So the diamond may have been larger initially and not completely encased in stone, otherwise it would now be a piece of graphite.

It’s just that the diamond is big or big. After burning some, it still has the size of the first joint of the little finger, but the color is not very good, the clarity is quite bad, and it’s all impurities. A stone with high transparency.

The degree of value is actually relatively limited. UU reading www.uukanshu.com is not bad as a collectible, but it can’t sell for a high price.

[One thing to say, this is the first time I heard that a volcano will spew diamonds]

【Why I am not so lucky】

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

【Take my surfboard and let’s go! 】

Grey snow fell from the sky.

The sea was covered with a thin layer of gray fog, like a layer of lime sprinkled on clean water.

Bi Fang ignored the ridicule and scolding of the audience when they returned to pick up the diamonds, pulled the sail, picked up the oars and headed in the opposite direction.

He is not a Soul Douluo and does not have three lives.
