Send three high-quality colorful meteorites to your star friends for appreciation

In the vast universe and the beautiful starry sky, there are actually many "colorful" meteorites.

The olivine iron meteorite originally belonged to Fukang, Xinjiang, China, but was lost abroad.

Olivine iron meteorite

A meteorite that fell in the Gobi Desert in Fukang, Xinjiang, China in 2000. When sliced, the translucent gold-colored olivine crystals sparkle, while the nickel-iron glows silver. Under the sun, it shows colorful light.

Olivine iron meteorite? Slices

Meteorites in the world are usually black or brown, but also yellow and red. Meteorites have different material compositions, and their surfaces are burned by high-temperature friction in the Earth's atmosphere. After melting, they form different appearances and colors.

Brilliant Starry Sky? Stony Meteorite:

This stony meteorite is composed of silicate particles and partly chondrule agglomerates. It is oval in shape. After the melting recedes, the interior appears irregular. The changed matrix (composed of pellets, matrix fragments, and glass) is black and white "cemented". There are many metallic glitter points and crystal glitter points on the surface, which is as beautiful as a condensed version of the dazzling starry sky! It is of great scientific research and collection value!

After the molten shell of the stony meteorite fades away, a colorful matrix appears inside.

Colored meteorites? This depends on how the "color" method is used...

Olivine meteorite

Of course, there is one kind of olivine meteorite, but the outer skin of olivine is not necessarily colored, and its interior is It's colorful and very beautiful. So usually olivine meteorites are sliced ??for sale and made into different jewelry.

Olivine usually The cause is that the metal and silicide components inside the asteroid melted at high temperatures are continuously differentiated and cross-linked to form a honeycomb complex of metal and olivine.

According to researchers’ speculation, the formation of olivine meteorites has the following three steps and various false origin theories:

Be careful that colored meteorites are fakes

The fundamental reason is that generally colored substances are either organic matter or compounds of certain heavy metal elements. These organic matter and metal compounds are unlikely to be preserved in their original state at high temperatures. Therefore, when a meteorite falls, even if the original meteorite has color, after atmospheric friction and high-temperature combustion, these organic matter and oxides will further melt and react with the air and other materials inside the meteorite to form some more stable materials. These generated materials The color is usually darker. This is really the fundamental reason why we rarely see colorful meteorites.

In addition, our common meteorites are still mainly composed of iron, manganese and silicon. Most of the full oxides of these elements are black. Therefore, the molten shells of ordinary meteorites are mostly of this color. As for Because the interior of the meteorite is not in contact with oxygen and is not affected by high temperatures, it can maintain its original texture and color. Therefore, an important feature of meteorites is that they have an oxidized molten shell, while the interior maintains its original texture. But if you see a stone covered with an overly colorful "skin" (such as the ones below), then be wary. Although not only meteorites have "skin".

Above picture: The colors of these "meteorites" are too fake because they are too colorful.

Because most red meteorites contain iron in the meteorite itself, the color of iron oxide formed under suitable conditions when it violently combines with oxygen in the atmosphere is our common "rust color", but meteorites are often not pure iron. One piece, so this rust color also contains a lot of black and gray impurities, so the overall texture should appear dark. Therefore, if you see a stone claimed to be a "meteorite" that is too bright red in color, it may also be fake.

Above: The color of these fake meteorites is too red.

Some meteorites will also be eroded by various natural forces on the earth and produce some colors

Some meteorites have fallen on the earth for a long time. If they were once buried underground, they may be due to infiltration. The addition of other minerals or erosion by water, air and other substances may produce some unique colors, but these colors are not the true colors of meteorites.

Summary

The interior of meteorites may be colorful, but meteorites that fall to the earth often form molten shells due to burning in the atmosphere, so the appearance of the natural meteorites we find is not that big. Probably in color. Most meteorites that appear to be colorful are fakes.

Colored meteorites are mainly olivine meteorites, which consist of transparent and colorful olives suspended in fluid metal. The lines and textures, texture and color are all very beautiful.

Let’s see if this stone is a meteorite. It is magnetic and weighs about thirty grams! Irregular shape! black! The proportion is large!

This is an emerald-like emerald. This kind of meteorite is very rare. In the ancient tomb of the Egyptian Pharaoh more than 3,600 years ago, the ancient Egyptians processed yellow glass meteorites into finished products for collection. In the tomb of Pharaoh! Therefore, meteorites with modern colors are very noble. This emerald-colored meteorite comes from the glass meteorite in Yunnan, which will heat up the night light for future generations! It is one of the meteorite treasures that most meteorite recipients dream of owning. It is for netizens to share this stone together! Brightly colored polymetallic copper meteorites!

That’s not called a colored meteorite. It’s a crystal structure that can only be seen through a microscope after the reorganization of minerals. It’s invisible to the naked eye without a microscope. It’s just the reorganization of different minerals. To advocate various meteorites, you must at least understand them. What kind of minerals can still exist at long-term high temperatures of 3000-6000 degrees, and then the friction temperature is not lower than 3,000 degrees, producing ripples and air marks? This is the minimum professional knowledge, otherwise you will be presumptuous after playing with meteorites for a lifetime. I know that telling the truth will hurt the interests or sensitivities of some people, so try not to say it or say as little as possible

For meteorites, there are mature scientific results and data. We must learn, master and use. But science is constantly developing and progressing, and new discoveries and cognitions are constantly being updated. Some whys, the more we know, the more we don’t know.

The universe is vast and there are countless stars. The earth's rocks are rich and colorful. Not to mention the countless fragments of stars in the universe. Over the billions of years that the earth has passed, various star fragments may have fallen to the earth. It's just that we haven't discovered it yet. How far is Mars from Earth? Martian meteorites have been discovered, so fragments of other stars can fall to the earth. What else is impossible?

Several pieces in the picture above are colorful, and the characteristics of burning and melting are obviously classic. This is enough to show that meteorites are colorful and full of surprises.

Of course! The Beijing Planetarium and Zhang Baolin have done research on meteorites. Meteorites of various colors exist, which is mainly determined by the matrix of the meteorite. In this question and answer, the actual meteorite will be the best answer. Let me take you to the point! !

In my thirty years of meteorite collection, I have discovered and collected meteorites of various colors. I can share with you two colorful meteorites discovered by me! First up: the pink directional meteorite to share with you! (The second and third pictures are details of the first picture)

Now I will share with you a rare purple lunar meteorite discovered by me!

Meteorites of various colors exist, which are mainly determined by the meteorite matrix. You must have learned something from the physical pictures I shared with you for popular science!

At the same time, the melt flow line of a meteorite is the main basis for directly determining whether the meteorite has directional fall. Not all meteorites have melt flow lines, and meteorites with melt flow lines only account for a small part of the known meteorites. What I want to share with you are two extremely rare classic directional meteorites with melt flow lines! At the same time, everyone is welcome to appreciate it. This article ends!

It is difficult to find colored meteorites. I have a light red meteorite. Please show it to my friends.
