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, elemental 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 falling in 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 meteorites basically have two to five elements, which are basically between three elements, and these five kinds are roughly fe ni mg si al, These five elements can not be judged by the naked eye, and at present, the national customs agency has fully authorized the testing agency Hunan Zhongli Cultural Relics Testing and Appraisal 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.

Summary. Hello, there are many most authoritative professional meteorite testing institutions in China: such as Guiyang Institute of Geochemistry, Chinese Academy of Sciences, Guangzhou Institute of Geochemistry, Chinese Academy of Sciences, Institute of Geology and Geophysics, Chinese Academy of Sciences, and Beijing Planetarium directly under the National Astronomical Observatories of the Chinese Academy of Sciences, Nanjing Purple Mountain Observatory, Xinjiang Astronomical Observatory; There are also the School of Earth Sciences of Nanjing University and the School of Earth Sciences of Guilin University of Technology.
The most professional place to identify meteorites in the country is **.
Hello, there are many most authoritative professional meteorite testing institutions in China: such as Guiyang Institute of Geochemistry, Chinese Academy of Sciences, Guangzhou Institute of Geochemistry, Chinese Academy of Sciences, Institute of Geology and Geophysics, Chinese Academy of Sciences, and Beijing Planetarium directly under the National Astronomical Observatories of the Chinese Academy of Sciences, Nanjing Purple Mountain Observatory, Xinjiang Astronomical Observatory; There are also the School of Earth Sciences of Nanjing University and the School of Earth Sciences of Guilin University of Technology.
The specific methods of detecting meteorites by these formal and authoritative testing institutions include physical detection, element detection, energy detection, frequency detection, etc.
Element detection: The meteorite should have a certain amount of unknown elements, a certain amount of meteorite mineral composition, a considerable amount of trace elements, trace amounts of radioactive elements, and trace amounts of nickel elements. Frequency Detection:
Meteorites are often characterized by high frequencies, and the ultrasonic waves of meteorites are measured by meteorite frequency detectors, ranging from 20,000 to 3 million hertz, so as to distinguish meteorites from ordinary rocks.
Friendly reminder: If collecting meteorites is just a hobby and you don't want to trade it, it's best not to test it. Because formal and authoritative testing institutions will use the scientific data obtained from professional instruments to prove the authenticity of meteorites, it is necessary to comprehensively study the physical and chemical characteristics and molecular structure of meteorites, and then conduct destructive sampling tests on meteorites.
This destroys the original object form of the meteorite and damages the beauty of the meteorite.
Hope it can help you and have a happy life! Looking forward to seeing you <> Zanha

The Laboratory of Astronomical (Planetary) and Meteorite Chemistry of USTC, the Laboratory of Physical and Chemical Sciences of USTC, the National Laboratory of Microscale Physical Sciences of USTC and the Laboratory of Cosmic Interstellar Matter of USTC are all State Key Laboratories of the Chinese Academy of Sciences. The Astrochemistry and Planetary Science Laboratory of the Purple Mountain Observatory is a professional appraisal institution in China.
China Meteorite and Astronomical Science Network: In recent years, we have found that there are even some fake organization associations in the name of international, domestic and Hong Kong registration, some auction companies suspected of fraud, some cultural companies suspected of fraud, and illegal appraisal institutions such as cultural toys or antiques suspected of false meteorite identification, in order to use the name of "meteorite identification, meteorite auction, meteorite acquisition, meteorite private transactions and meteorite ** evaluation".
Unburned stone, iron, or a mixture of rocky iron and stone that has been quickly scattered onto the surface of the Earth or other planets by cosmic meteors or dust fragments that have left their original orbits outside the Earth.
Lunar meteorites can be divided into two categories: volcanic rocks and sedimentary rocks, and lunar basalt is one of the main rocks that make up the moon, with black, white, and dark purple colors. Color, fuchsia, green, dark green (commonly known as black treasure green), gray-green, yellow, brown-yellow, mixed colors, etc.

Answer: Good morning, Xue'er will answer for you, please wait a while, I am sorting out the answer for you At present, in addition to the relevant national scientific research units, there are also Hunan Zhongli Collection Appraisal Center, which is a legal third-party professional identification platform, does not participate in any transaction, and uses instruments for non-destructive chemical composition analysis of suspected meteorites, and compares the analysis results with the data of various meteorites, so as to accurately and scientifically determine whether it is a meteorite and what kind of meteorite it is. The certificate has been highly recognized by professionals and all walks of life.

There is no institution that identifies meteorites for free, either you spend money on identification, or you give meteorites to scientific research institutions for free. That's how they'll give you an appraisal.
-
**There is a meteorite identification agency, you can go to the Purple Mountain Observatory in Beijing.
-
First, the observatory or the geology and mining department. 2. Local meteorite identification institutions or testing institutions, etc.
-
The authenticity of meteorites must be identified with professional instruments, which can generally be detected in places with professional instruments such as geological survey institutes, mineral and petrochemical laboratories or planetariums.
-
Meteorites are an extraterrestrial object whose value lies in collecting.
And the equal generation appreciation. Generally, there are appraisal agencies in first-tier cities in China.

Meteorite identification institutions include: International Meteorite Association, NASA, British Museum of Natural History, etc.
1. International Meteorite Association:
Founded in 1933 and headquartered in Washington, D.C., the International Meteorite Society is one of the largest meteorite societies in the world, promoting the development of meteorite and cosmochemistry research.
2. NASA:
As one of the world's largest space agencies, NASA is not only a leader in space technology, but also one of the world's most authoritative meteorite identification agencies.
3. Natural History Museum, UK:
Home to one of the world's most renowned meteorite collections, the museum's meteorite identification laboratory is one of the largest meteorite research institutions in the world.
Origin of the Meteorite Identification Agency:
The origin of the meteorite identification agency can be traced back to the early 60s of the 20th century, when some unusual stones were discovered, which were different in appearance from the stones on the chiral cave earth, and had some mysterious features, such as special molten forms and needle-like crystals. People began to suspect that these stones might have come from cosmic space, and on this basis, the study of meteorites began.
During the Apollo 11 mission to the moon in 1969, astronauts brought back some stones from the moon, which were confirmed to be meteorites by scientists, that is, some of the stones present on Earth may be meteorites from space.

There are many national meteorite identification institutions, and you can find an observatory or a local meteorite identification agency.
Meteorite identification authority is used to identify meteorite institutions, in China, authoritative and professional meteorite identification institutions do not provide services for private meteorite collectors. Therefore, it is difficult for an authoritative appraisal agency to issue a certificate for a meteorite with high value in Zhongheng. At present, there is no recognized and credible meteorite identification agency in China.
Because there are no meteorite detection instruments in the world. No matter how big the instrument is, it is only for the analysis of mineral elements.
The identification, scientific research, collection and ownership of China's meteorite market are becoming increasingly prominent, and domestic official institutions and non-governmental organizations should have unified standards and norms for meteorite identification. Most of the material elements contained in meteorites are also contained in earth ores, and if you want to identify a meteorite, the public says that the public is reasonable, and the mother says that the mother is reasonable. It's much harder than taking an antique and having it appraised.
Professional meteorite identification
1. There are many places in China where meteorites can be identified, which can be divided into two categories. First, the observatory or the geology and mining department. Second, local meteorite identification institutions or testing institutions.
2. The identification of meteoric stones needs to be analyzed and judged from a scientific perspective and the experience of professional experts and teachers. At present, the meteorite identification in China is in Zhengzhou, Henan. Many collectors have been there and are very satisfied with the appraisal results.
3. Meteorite is a stony, ironic or rocky-iron mixed material that is scattered quickly on the surface of the earth or other planets by unburned cosmic meteors outside the earth or dust fragments that break away from their original orbits or dust fragments, also known as "meteorites". Most meteorites come from the asteroid belt between Mars and Jupiter, and a small number from the Moon and Mars.

Kiss! Hello, it's a pleasure to answer the <> for you
Pro, Beijing Chinese Academy of Sciences Meteorite Identification Center Address: No. 138, Xizhimenwai Street, via bus line: 27; No. 87; No. 105; No. 107; No. 111; No. 332; No. 347; No. 360; No. 362; No. 534; No. 563; No. 632.
There are four major methods for the identification of stony meteorites: 1. Observation 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. 3. Observe the chondrite method. On the fresh section of chondrites, fine chondrites and the matrix between chondrites can be observed with a magnifying glass, and f-Ni metal and meteorite iron can be seen.
Iron meteorites that corrode the polished surface of iron meteorites with an alcohol solution containing 2% concentrated nitric acid can show the Vickers Titan 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 presence of f-Ni metal (generally, meteorites have a specific gravity of at least. Hope mine can help you <>
