The newly laid wooden boards were damaged like this.
A fist-sized, irregular-shaped black stone was stuck on the wooden board with a dark light. In the center, a transparent block at least the size of a thumb shone brightly in the sunlight.
Bi Fang knelt on the platform, leaned down, and wanted to use his hands to buckle, but when he got close to Chi Chi, he was forced back by the heat emanating from it.
The high temperature interacted with the wooden board, turning the surrounding area into black charcoal, and the black hole continued to expand. Then Bifang saw that the transparent material 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 directly burned out of the board that had been smashed through most of the board under the high temperature.
With a pop, the stone fell straight into the ocean, and then made a sound similar to that of high-temperature metal colliding with cold water. This sound made Bifang's ears tingle when he heard it in the Banna rainforest.
The white bubbles rolled violently, and Bifang stretched out his hand 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 so exaggerated. At least it did not burn a hole when placed on the wooden board, and the translucent stone on it did not burn out.
Bi Fang scooped some seawater and poured it on the stone to speed up its cooling. When it was no longer a problem, he took it into his hand and put it in the sun to examine it carefully.
Is this thing... a diamond?
The audience couldn't forget what Bi Fang just shouted, without him. If it is true, then this one is too big.
Even if 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 it?]
【Because it hasn’t been cut yet?】
【Purity, too low!】
[When will Fang Shen come and pinch a diamond with his bare hands]
Bi Fang looked at it for a long time and finally confirmed that this was really a diamond!
If one survives, there will be future fortunes?
Then at least get one with a higher quality.
Bi Fang was speechless as he rubbed the diamond that seemed to have many impurities in it.
"Volcanic eruptions do bring some precious metals to the surface. The main component of diamonds is carbon, and carbon is not uncommon on the earth."
"The formation of diamonds is different from the high pressure and low temperature of jade I mentioned before. It takes place in a high temperature and high pressure environment. This condition is very rare on the surface of the earth, but the mantle layer is everywhere, which is very consistent with the formation conditions of diamonds.
So many diamonds form in the mantle."
[Volcanic eruptions seem to occur in the mantle layer? 】
[To be honest, I don’t remember this anymore]
[If I were a high school student, I would still have to say a few words now, but I am already a senior and I only know how to eat three meals a day]
"Yes."
Bi Fang nodded.
"The formation of volcanic 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. Not only is the temperature of the core above 5,000 degrees Celsius, but the pressure is also very high.
, so the molten object will be pressed into a solid state."
"Outside the earth's core is the mantle, above it is the ring-shaped structure of rocks, and the rocks are 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 shell inside the mantle are affected by thermal convection, causing earthquakes, etc.
The occurrence of disasters.”
"In addition to the extremely high temperature, the pressure of the mantle layer materials is also high. Generally, it is difficult for the mantle layer materials to break through the limitations of the lithosphere and crust. However, in places where the earth's crust is weak, the mantle layer materials will erupt to the surface due to the pressure.
This is what makes a volcanic eruption happen."
"Diamonds are formed in the mantle, and magma is also in the mantle. So after diamonds are formed, they are carried along with the magma to the volcanic pipes. When the magma condenses, kimberlite containing diamonds is formed."
“When a volcano erupts, the parent rock containing diamonds will be brought out, and due to the action of water flow, the parent rock of diamonds will be broken, thus forming diamond sedimentary sand deposits. 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 confused.
[Hiss, tell me the location quickly, I’m going to pick up diamonds now!]
[Diamonds are just a hype, not valuable at all. Now we can even artificially produce natural diamonds, not artificial diamonds, but artificially produced "natural diamonds"]
[We all know this, I have brushed Brother Li’s blood diamond three times]
[I have something to say. Seriously, don’t talk so much. I’m just asking you if you want to pick it up?]
[Pick it up! Report the address quickly! I’ll pick it up like crazy!]
The barrage was all about asking for the address, while Bi Fang kept looking at it and murmuring.
"I didn't expect to be so lucky that I could encounter a flying diamond. To be honest, the probability of this is actually very small..."
I won't mention it if it happens to hit me.
Diamonds are essentially carbon and will burn directly when encountering high temperatures above 900 degrees. The temperature of magma is usually between 700 and 1,200 degrees. If they 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 happened to be wrapped in rocks and flew out before being completely heated.
In fact, it almost sublimated just now, but it happened to burn a hole in the wooden board, and it cooled down faster when it fell into the sea.
The burning of diamond at high temperature and in the presence of oxygen is different from the burning of carbon. The burning of carbon is that the entire carbon is burned red, and then the outside is burned when it comes into contact with oxygen.
The burning process of diamond is: no matter how high the temperature is, it remains colorless and transparent, and the external carbon atom structure slowly disappears when exposed to oxygen.
As for the result of heating without oxygen, the inherently unstable diamond structure will transform into graphite.
So this diamond might have been larger initially and not completely surrounded by stone, otherwise it would be just a piece of graphite now.
It's just that the diamond is big. After being burned for a while, it's still about the size of the first knuckle of your little finger. But the color is not very good and the clarity is quite bad. It's full of impurities. At first glance, you won't even think it's a diamond, but a diamond.
A stone with relatively high transparency.
Rice Ball Exploration
The value is actually quite limited. It's pretty good as a collection, but it won't fetch a high price.
[One thing to say, this is the first time I heard that volcanoes erupt diamonds]
[Why I don’t have such good luck]
【Go surfing on a volcano, and if you survive, you can too!】
[Bring my surfboard and let’s go!]
Gray snow fell from the sky.
There was a thin layer of gray fog covering the sea surface, like a layer of lime spread on the clean water.
Bi Fang ignored the teasing and teasing of the audience who returned to pick up diamonds, pulled the sail, picked up the oars and headed in the opposite direction.
