Treasure Hunt Tycoon

There is a huge crater below Wilkes's ground. Of course, Li Du does not know. He paid little attention to Antarctica, and never studied the geological conditions of Antarctica.

Elson went to prepare dinner, and Steve took them to sit down and started talking about the purpose of this trip to Antarctica.

Like he said, he came to look for meteorites. There were many meteorites in the house. He took some of them on the table and showed them to Li Du.

The Wilkes Crater was discovered half a century ago, and is located just below the ice sheet in Wilkes Land. It is a large impact crater.

This crater is very large, and after measuring with modern technology, it is believed that the diameter reaches 243 kilometers and the deepest point can reach 848 meters.

In addition to the crater, there may also be a mass tumor in Wilkes Land.

Mass tumor, as its name implies, is a tumor with a particularly large mass. It exists inside the planet, which is a polymer with a higher density than the surrounding geology.

Humans have discovered mass tumors on the moon and Mars. According to aerospace research, it is the result of asteroid impacts.

A mass tumor previously discovered on Earth was in Hawaii, but scientific research has shown that it was derived from a volcanic eruption, not from an asteroid impact.

Until later, NASA's heavy force measurement and climate monitoring satellite discovered the mass tumor of Wilkes Land, which is larger than a crater and travels about 300 kilometers!

There are no large volcanoes in this area of ​​Antarctica, which ruled out that it was also formed by a volcanic eruption. Then, the reason for the formation of this mass tumor is simple and clear:

It is the result of an asteroid impact!

"According to the study of air echo acoustics, there is a gravity anomaly at the lower end of this crater and mass tumors, and there are a large number of glass meteorite. Now the widely dispersed glass meteorite on the Australian mainland comes from here." Steve gave him Explain.

Li Du asked: "What does this mean?"

"It means a lot, first of all it means there are a lot of meteorites here, let's look for these alien meteorites."

Li Du smiled: "Oh, you want to be a meteorite hunter, right?"

Just like the art hunter he met in Miami before, meteorite hunters are similar in nature, they are professionals who look for meteorites.

As we all know, meteorites have always been rare and rarer than gold and diamonds, but they have been collected around the world only 300O blocks.

Meteorites are rare, not to mention that meteorites have scientific research value that ordinary collections do not have. Therefore, the collection of meteorites has been an important work in various countries. The meteorites on the earth are very important for understanding the age of the earth and the evolution of the earth Scientific value.

Most of this collection work is not performed by people, but more directly purchased by the government.

There is competition between governments, and governments are rich, so the price of meteorite has always been high.

Before Li Du learned about the world's luxury market, he noticed the meteorite market.

Meteorites are not frequent visitors at auctions, but whenever they appear, they are the protagonists.

In 1993, the Sotheby's auction house auctioned a lunar meteorite for $ 442,500, with a mass of only 0.33 grams!

In May 1998, a New Mars meteorite was photographed by the Phillips Auction House in New York. The transaction price was US $ 3.36 million and the quality was even smaller, only 0.28 grams!

Now that humans can land on the moon and Mars, it can be said that stones can be brought back from these two planets. The moon and Martian meteorites flowing on the earth should not be expensive.

This is not the case. First, there are several United Nations permanent council powers that can go to the moon. Second, only US probes can go to Mars.

It is very difficult for the detector to transport the ore backwards, and the cost is very high, and it costs more money than the ore that naturally fell on the earth at the auction.

The U.S. government even uses the ore brought back from Mars as a diplomatic means. To obtain their ore, other governments have to pay a large price.

Not long ago, Christie's Paris held a "natural history" auction in the fall. There was a 43-centimeter-long, 45-kilogram-meteor meteorite. Its transaction price was 78.25 million euros, and the price was very scary!

After listening to Li Du, Steve laughed and said, "The people in our Tusenberg family are meteorite hunters, and they can all be called meteorite hunters, but I shouldn't be. I come to meteorites for other purposes. Not for profit. "

"For what?" Li Du asked subconsciously.

Steve was silent, apparently he didn't want to say the answer.

Sophie secretly pulled Li Du back to the topic again: "Are you going to look for meteorites from the crater here? As far as I know, Wilkes crater is under the ice sheet, can't you dig?"

Steve nodded and said regretfully, "Yeah, the ice sheet is too hard and the thickness is too large. Existing technology cannot sample through hundreds of meters."

"My idea here is to look around the crater to see if you can find meteorites that are sputtered on the surface. There is also the same as learning to dig opal mines and digging on shallow surfaces ~ www.wuxiaspot.com ~ Look for meteorites. "

Li Du suddenly realized: "Oh, you go with me to dig Opal, just to prepare for this?"

"Learning for this, after all, because of physical reasons, I have not been exposed to similar jobs." Steve laughed.

Li Du asked: "I have a hand in searching for ore. If you think I can help, you can mention it. I can't raise it because you know, I don't want you to feel that I have violated your rights. "

Hearing this, Steve smiled helplessly.

He rubbed his hands and said, "Li, don't get me wrong, I don't want to keep anything secret from you, but I think what I say, you may not believe it."

"If you think I can know, you can say something, I trust you," Li Du said.

Steve said: "Okay, let me tell you first. According to geological and topographical research, if the crater and mass tumor of Wilkes Land were produced by the impact of a meteorite, the diameter of this meteorite should be forty To fifty kilometers. "

"Do you know? The meteor that formed the Hicksulub Crater is only ten kilometers in diameter."

The Hicksulub Crater is a crater impact found in Yucatan, Mexico, or the Yucatan Peninsula. It is currently the largest crater accessible to the earth.

This impact event is considered to be the main cause of the Cretaceous-Tertiary extinction event. After the impact, the asteroids completely evaporated, releasing up to 5.0 × 10 ^ 23 joules of energy, which is equivalent to 120 trillion tons of yellow explosives, which triggered the tsunami. And let a large amount of dust enter the atmosphere, completely covering the sun, changing the global climate, causing nuclear winter.

Many people may not understand these things. In a nutshell, this collision event led to the end of the dinosaur era. It has been speculated that the dinosaurs that once ruled the earth were extinct by this meteorite!
