Blue Star Sea Diamond

And a new face appeared at the meeting, this person was Lei Ji, he had just entered the institute and came to listen to this research group.Lei Ji began to have something to say: "I'm from a businessman. I was just a moneymaker, but because the investor who I invested has some debts that cannot be paid off, I was invited here."

Xue Yong said: "Do you still have money to invest in our research group?"

Wang Zhi said to Xue Yong: "It's not your turn to speak."

Wang Zhi said to Lei Ji, "Why are you here?"

Lei Ji said: "Maybe you still don’t know. Our company takes me seriously and sent me as a representative. And he asked me to participate in this meeting. One is to analyze a weird stone wall, because this stone wall is our company’s hard work. It’s a painful one. The other is to analyze the problem of deep mining of minerals. These are all useful to me."

Wang Zhi said: "I won't talk about the first one, what is the second one?"

Lei Ji said: "We have signed an agreement with Rosha Country to mine a deep mine in the deep ground." Lei Ji gave his father the mission to himself, because it is obvious that there must be countless in the depths of the earth. Clear wealth, but if you need to understand how to mine, you also need professionals to understand where to mine.

Xue Yong said: "This is a great plan. I know that Rocha and our country believe that the mineral deposits deep in the earth are very important, and there must be many things I want in it." Xue Yong is also interested in this plan and understands it. The Lei Ting Group, where Lei Ji is located, is an extremely rich company. When the Geological Institute is short of money, it is a good idea to ask Lei Ji some money to make money.

Lei Ji said: "I heard that the people in your research group have been short of funds. I can invest here as long as I get the exploration technology." Lei Ji also knows that all the experienced experts are sitting here. Even if they can't handle the prospecting, no one else can handle it.

The professors at the meeting began to look at each other, not knowing what to say.

Wang Zhi said: "I have a question. What kind of technology do you want? The drilling of mining is not something we research. I think we can still get our hands on if you let us study the elemental composition of geography."

Lei Ji said: "Yes, how do you explain to me what is in the depths of the earth." After saying that, Wang Zhi was also silent. In a rigorous style of study, he knew that the understanding of the deep terrain was not just talking about it. In other words, it is not as written in the books, but needs field verification, but no country can reach a depth of more than 12,000 meters, so the structure of the deep ground is only limited to the geomagnetic field and seismic waves. Analyzing and comparing with meteorites to guess the material composition of the deep earth, Wang Zhi couldn't have the courage to go on.

Seeing that no one was speaking, Pei Shitong said: "Look how deep it is." Pei Shitong also knows that this is only a theory, but he can only fight for a little value for himself for today's sake, and cannot be squandered like this. People are blasted away.

Lei Ji said: "From shallow to deep, the deeper the better." Lei Ji saw that everyone was silent and was a little disappointed. He felt that these experts were useless at all, but when he saw that Pei Shitong seemed to want To say this to myself, it is better to hold Pei Shitong and beat the scholastic person who sits again.

Pei Shitong said: "Even the shallow crust is basically our common rock."

Lei Ji said, "Well, we probably know this."

Pei Shitong began to think about it and slowly said: "At a depth of about 33 kilometers, there are olivine and garnet, which contain more silicon, oxygen, aluminum, and magnesium."

Xue Yong said: "Don't talk about it here, people ask you the key point."

Pei Shitong ignored Xue Yong and continued to think: "100 to 150 kilometers, the magnesium content will increase on the original basis, and there will be a liquid structure, and the pressure will slowly reach 6.5 MPa."

Lei said very excitedly: "What about deeper?"

Pei Shitong said: "At a depth of 220 kilometers, at 10 MPa, the co-cubic magnesium silicate slowly transforms into metastable magnesium silicate."

Lei Ji said, "How about deeper?"

Pei Shitong said: "At a depth of 400 kilometers, there is 14 MPa, which is slowly transformed into spinel magnesium silicate."

Lei Ji said, "Deeper?"

Pei Shitong said: "At a depth of 670 kilometers, the pressure is 25 MPa, and the four oxygen atoms of silicic acid become six coordination."

Lei Ji said, "I don't think the elements have changed much! Is this that?"

Pei Shitong said: "There will be the birth of titanium. At a depth of 1,000 kilometers, the pressure is 39 MPa, and the perovskite silicate changes from a tetragonal structure to a hexagonal structure."

Lei Ji said, "Going deeper, is there any structural change?"

Pei Shitong said: "At a depth of 2900, with a pressure of 137 MPa, the oxide structure has changed from a square structure to a close-packed hexagonal structure."

Lei Ji said: "I understand that the six-party structure is closer, but what about deeper?"

Pei Shitong said: "There will be a lot of iron, iron hydride and iron sulfide on the surface of the earth's core."

Lei Ji said: "It's very interesting, what about deeper?"

Pei Shitong said: "It mainly contains the four elements of hydrogen, iron, sulfur, and silicon. This reaches the deepest point, with a depth of 6371 kilometers and a pressure of 364 MPa."

Lei Ji said, "Is there a future for geographic mining?"

Pei Shitong said: "There must be, but it takes enough time to wait patiently."

Lei Ji said: "There are many areas in the earth that will be magma. Do you think magma can be mined?"

Pei Shitong said: "Then we need to look at the value of magma itself, if it is worth mining, we will find a way."

Lei Ji said: "What do you think is that the magma is extremely high temperature, and anything used as an exploration vessel as a shell will be roasted by the magma. So the high temperature problem cannot be completely overcome."

Pei Shitong said: "We can find special materials for high-temperature things in the future. Even if this material is not found, we can find a thicker ship. When the hull enters the magma, only the outer layer will be burnt and the inner layer will be protected. Calculate the burning speed according to time, and return before the inner layer is burned."

Lei Ji said: "What about the power plant? Can electricity run under such conditions?"

Pei Shitong said: "The low temperature inside can use electricity, and the outside can use some clever mechanical power and a way to change the overall density of the hull."

Lei Ji said: "I know that changes in the relative density of magma can determine the floating and sinking, so how to change the density of the hull?"

Pei Shitong said: "I'm thinking about the same principle as a submarine, so that the hull that enters the magma has a structure that can communicate with the outside world. The hull shell itself is very hard, but the middle layer can be hollow to reduce the overall density of the hull. To complete the ascent. If you want to sink, send out the hollow gas and let the external magma flow into the hollow layer, so that the overall density of the hull will be higher than the surrounding magma, allowing the hull to complete the sinking."

Lei Ji said: "I need such a ship that enters the magma. It has a density higher than that of magma, as you said, heat resistance is enough for the probe ship to return, the internal operators cannot be injured, and then it can be mined. The ability of the material deep in the magma is also the most critical."

Wang Zhi called out Pei Shitong, and the two people said outside the venue: "You have said so much? Do you have experience?"

Pei Shitong said: "We can try and find some factories that make ships."
