Live Wilderness Adventure

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\
