Meteorite identification! How to identify a meteorite

1 Stone meteorite 2 Iron meteorite 3 Glass meteorite 4 Stone iron meteorite (small category not counted) How to distinguish meteorites in science, first of all, we must understand the types of earth stones, element species, most of the elements of earth stones are more than 5 kinds, and there are as many as a dozen, and meteorites no matter what kind of meteorite is experiencing the fall of outer space, it falls like a flying fairy from the sky after a high temperature of a few or more than a thousand degrees of ashing, it becomes pure and clean, so the meteorite basically has two to five elements, which are basically between the three elements, And these five kinds of roughly distinguish te ni mg si ll, these five elements can not be judged by the naked eye, at present, the national customs agency has data full authority to test the agency Hunan Zhongli Cultural Relics Testing and Identification Center.

Liu Chuanyou, a scientific and technological engineer of Zhongli Cultural Relics Identification and Testing Center, believes that the EDX fluorescence analyzer is a more sophisticated meteorite judgment instrument on the market, and in the case of vacuum pumping, the elemental analysis is pure and natural, because this instrument can quickly detect various contents of meteorites without damaging the meteorite.

Meteorite detection mainly depends on the data, and the data is not an ordinary person or according to the Internet to judge, due to the network false, meteorite judgment scourge many collectors, so remind meteorite collectors, to go to the regular meteorite detection center for testing is more assured, the current domestic meteorite detection in Hunan Zhongli, they have fallen meteorite data all over the country, but also experienced thousands of tests.

Fake from the color pattern.

Summary. 1. Observe the surface method. First of all, meteorites are generally irregular in shape, and secondly, meteorites pass through the atmosphere during the landing process and friction produces high temperatures, so the surface of the meteorite has a layer of black molten shell formed by burning and the gas marks left by the friction of the air flow, and it also has a flow pattern or streamline structure.

2. Magnet is an experimental method. Meteorites are basically divided into three categories, namely stone meteorites, stone iron clouds, and iron meteorites. Among them, the magnetism of stone meteorites will be relatively small, and it is not easy to be attracted to magnets. However, the iron content in stone iron meteorites and iron meteorites is relatively large, and the magnetism is relatively strong.

The magnet is a bridge attack experimental method.

Meteorites are basically divided into three categories, namely stone shoots, stone iron clouds, and iron meteorites. Among them, the magnetism of stone meteorites will be relatively small, and it is easy to be attracted to magnets without fiber search. However, the iron content in stone iron meteorites and iron meteorites is relatively large, and the magnetism is relatively strong.

3. Observe the chondrite method. On the fresh section of chondrite differential meteorite, fine chondrites and the matrix between chondrites can be observed with a pin-qingbo magnifying glass, and fe-Ni metal and meteorite iron can be seen. If an iron meteorite is corroded with an alcohol solution containing 2% concentrated nitric acid, the polished surface of the iron meteorite can show the Victorinox structure.

The structure of a meteorite is dense and it is not possible to have structures such as foamy, porous, or slag structures. 4. Ingredient detection method. Meteorites generally have a greater specific gravity than Earth's rocks due to their fe-Ni metal content (generally, meteorites have a specific gravity of at least.

Summary. Yes, I've seen your question and I'm sorting out the answer for you, so please wait a minute

Yes, I've seen your question and I'm sorting out the answer for you, so please wait a minute

The main aspect of our observation is to see whether it has the characteristics that a meteorite should have, that is, the external molten shell, air seal, melt flow line, etc. Whether there are pellets, metal flashes, etc. Whether there are pellets on the section, Bi Qiaocha metal flash, Vickers phase, etc.

In addition, it is necessary to combine what is known'Meteorite-like earth rocks'to compare.

The surface is caused by the collision of the gas flow of the lead mega-black molten shell formed by incineration'Airmarking'(The air mark is generally multi-fingered, and the appearance of the meteorite is like the impression pressed by the thumb) is partly with'Melt flow.

Tie a small piece of magnet with one end of a thin trembling wire about 10 cm long, pinch the other end of the thin wire with your hand, and then slowly approach the object to be registered to be destroyed to detect whether it is magnetic.

We all know that meteorites are basically divided into four categories, namely iron meteorites, stone meteorites, stone iron meteorites and glass meteorites, and everyone has a perception of meteorites, that is, meteorites have magnetic matching searchability, in fact, it is not necessarily, whether there is magnetism or not, mainly depends on the iron and nickel metal content inside the rock cluster.

The iron meteorite has 95% iron-nickel metal, so its magnetism is certainly the largest, and it can even hold coins.

The second is the stony-iron meteorite, whose iron-nickel metal content is between 30%-65%, and the magnetism of the stony meteorite is relatively much smaller, its iron-nickel metal content is only about 30%, as for the glass meteorite, the main ingredient is not silica, so it is completely non-magnetic.

I hope mine can be helpful to you, and please give a like (rate it in the bottom left corner); Finally, I wish you good health and a good mood

Summary. Hello dear, the observation surface method is used to identify meteorites. Meteorites are generally in an irregular form, and secondly, the meteorite passes through the atmosphere during the landing process and friction produces high temperatures, so the surface of the meteorite has a layer of black molten shell formed by burning and the air mark left by the friction of the air flow, and it also has a flow pattern or streamline structure.

How to look at stony meteorites Stony iron meteorites.

Hello dear, you can try it with a magnet, and the one with magnetic force is a stone iron meteorite.

How many stony iron meteorites**.

Does a red copper meteorite belong to a stony iron meteorite?

Hello dear, the average stone iron meteorite is $500 a gram.

Stony-iron meteorites are divided into medium iron meteorites and olive meteorites, and stony-iron meteorites are divided into medium iron meteorites and olive meteorites, which are composed of iron, nickel and silicon, acid and salt minerals, and the iron-nickel metal content is 30 to 65, and this kind of meteorites accounts for about the total number of meteorites, so the commercial value is high. This kind of meteorite is composed of ironstone, coneite, nickel-grained stone, synthelite, silicon, aluminum, etc., and the secondary minerals are meteorite iron, chromite, graphite, etc. Stony iron meteorites are divided into the following according to the main components and structural characteristics of the interior

Olivine iron meteorite (PAL), medium iron meteorite (MES), bronze pyroxene - lepimoquite iron meteorite.

What meteorites do copper meteorites belong to?

Hello dear, copper meteorites belong to stony meteorites.

Copper meteorites are magnetic.

Hello dear, if it is magnetic, it is also a medium iron meteorite.

How much is a gram of medium iron meteorite**.

Hello dear, the second largest meteorite in China Iron, the market is generally $15 to $150 grams.

Meteorites can be identified by their appearance, and true meteorites will act as hail circles with the atmosphere and produce high temperatures, and there will be a layer of black molten shell and air marks on the surface. It can also be identified by looking at chondrites, and real meteorites can generally be seen with a magnifying glass to see the matrix between the fine chondrites and the chondrites. Because meteorites come from outer space, the determination of the authenticity of meteorite collapse rocks requires instrument identification, and the naked eye only has an auxiliary role.

Meteorites, also known as "meteorites", are unburned stony, iron, or a mixture of rocky iron that is scattered on the surface of the Earth or other planets by cosmic meteors or dust fragments that have left their original orbits outside the Earth.

Most meteorites come from the asteroid belt between Mars and Jupiter, and a small part from the Moon and Mars.

More than 40,000 meteorite samples have been collected worldwide, and there are various styles, which can be roughly divided into three categories: stony meteorites, iron meteorites, and stony-iron meteorites.

Summary. Iron meteorites are red. Whether it is an iron meteorite or a silica-rich meteorite, generally after being melted at high atmospheric temperature, the material on the surface of the molten crust has basically been oxidized into various valence oxides, mainly black ferric oxide, red iron dioxide, various silicon oxide and silicate, such as brown-yellow iron silicate.

The mixture of these materials results in the color of the meteorite molten crust being mostly black and dark brown, with only a small number of meteorites that may be reddish. Some white minerals, such as various magnesium salts, mixed with these dark minerals only reduce their color, and white is less likely to appear.

I have two meteorites here, help me identify what meteorites are, thank you!

What kind of meteorite?

Iron meteorites are red. Whether it is an iron meteorite or a silica-rich meteorite, after being melted at high temperature, the material on the surface of the molten shell has basically been oxidized into various valence oxides, mainly black ferric oxide, red iron dioxide, various silica and silicate, such as brown-yellow iron silicate. The mixture of these materials results in the color of the meteorite molten crust being mostly black and dark brown, with only a small number of meteorites that may be reddish.

Mixing white minerals (such as magnesium salts) with these dark minerals will only reduce their color, and white is less likely to appear.
