Some meteorites look like slag. What happened?

Imagine the high temperature and pressure when a meteorite falls. Things like slag are blown away as soon as they enter the atmosphere. Some dense meteorites can't bear the strong pressure and disintegrate in the air. How does a low-density rock like slag get into the atmosphere?

Some glass-like things displayed on the Internet are industrial slags from my hometown in the 1980s, specifically, slag alkalized by burning bubbles. It took three or four years to fill half the pond. You can imagine how much it is!

Some slag also has a shell on its surface, but it is absolutely different from the shell of a meteorite. Meteorite molten crust is produced by high-speed falling and atmospheric friction, which has streamline and strong sense of direction. If you suspect that it is a low-altitude explosion meteorite, the characteristics are not obvious, you should find a testing agency to be firm, and don't make jokes on the Internet. Personal experience can be exchanged, don't spray if you don't like it!

Meteorite market, meteorite fidelity!

Let's start with the science of meteorites entering the atmosphere. When they approach the earth and fall to the ground, the speed is very fast. If they want to pass through the dense atmosphere of the earth, they will rub violently with the atmosphere and generate heat. Small meteorites burn in the atmosphere, and only meteorites large enough can pass through the atmosphere and fall to the ground.

The closer to the ground, the denser the atmosphere and the thinner the upper atmosphere. "The closer the meteorite is to the ground, the more intense it burns, but it can only fall on the meteorite near the ground. The meteorite core itself is large enough and hard enough, and it has not been burned out in the atmosphere.

The so-called meteorite is just a hard enough material core that extraterrestrial matter passes through the atmosphere and falls to the earth. After high temperature combustion, some concave and convex pits remain on the surface. It's nonsense to say that meteorites are like slag. They are similar in color and burnt, and there are some small pits on the surface where bubbles overflow, but they are fundamentally different in shape, texture, weight and material composition.

It is precisely because meteorites are written like slag that illegal players make fake meteorites.

Slag is a mixture of coal or coal stone melted at high temperature and some elements. It has the characteristics of burning, wind blowing and bubbles, which is very similar to the formation process of waist meteorite.

Meteorites enter the atmosphere after leaving the star, and generate huge heat after rubbing with the atmosphere, which is similar to the conditions in the furnace, and will also melt or even vaporize. The resistance of the atmosphere forms wind marks on the surface of meteorites, and a large number of bubbles inside will also make the surface of meteorites explode like slag.

Anything is possible. True and false meteorites have to pass the composition analysis.

Meteorite is like slag, which is a joke of China people. Meteorite is a meteorite, and slag is said to be a meteorite. It can only be said that it is a question of level, vision and academic experience. Now many people who don't understand meteorites pretend to talk about the north, south and east of meteorites. It's really a slap in the face. Meteorites have been used in national defense, military, agriculture and science and technology in the United States and Japan, but we in China only know the speculation price, and the application in scientific and technological life is the real way out for meteorites. Can only say that the slag is said to be a meteorite, pathetic!

This is formed by oxidation of pyrite and chalcopyrite after contact with the atmosphere. The brown substance is iron oxide and the dark green is copper oxide.

I accidentally found it when I was playing on the mountain. It contains white metal micro-magnetism, has the characteristics of conductivity, and has obvious pits and streamline. Please see if it is a meteorite or slag.

Someone asked me if I was made of cement, and I said it was possible.

Meteorite Qinghai, Bama meteorite.

Look at this pit. Is it slag or meteorite?
