I picked up what looked like a meteorite and asked where I could identify it

Meteorite species. 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 no matter what kind of meteorite meteorite is experiencing the fall of outer space, it will become pure and clean after the ash of the high temperature reaches a few or a few thousand degrees, so the meteorite basically has two to five elements, which are basically between the three elements, and these five kinds are roughly divided te ni mg si ll, 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. The world is so big that there are no surprises. "Meteorites are the real kings of stones, but do you know how this emperor stone is identified? Know it**.

Now there are very few collectors who play meteorites in China, mainly because the meteorite collection is too niche, and the recent popularity is also because of film and television dramas, which are not very stable. Ms. Yu, a collector of strange stones in the collectibles market, said that there are too many fakes of meteorites, and it is difficult for ordinary people to "play with them". At present, there are few professional and authoritative meteorite detection institutions, and it is even more difficult to distinguish the real from the fake when selling meteorites online.

Pick up a meteorite, like an olive green meteorite, how to identify and buy and sell.

How to identify a meteorite and identify whether a sample is a meteorite can be considered from the following aspects: 1. Extravasation macro-Li table molten crust: the meteorite has to pass through the dense atmosphere before falling to the ground, and the meteorite rubs against the atmosphere during the landing process to produce high temperature, so that the surface of the meteorite melts and forms a thin layer of molten crust.

As a result, newly landed meteorites have a black molten crust on their surface, about 1 mm thick2 Surface air marks: In addition, due to the interaction between the meteorite and the air current, the surface of the meteorite will leave many air marks, like finger prints. 3 Internal Metal:

Iron meteorites and stony iron meteorites are composed of metallic iron inside, which has a high nickel content (10%). Chondrites also have metal particles inside, and fine metal particles can be seen on fresh fracture surfaces. 4 Magnetic:

Because most meteorites contain iron, 95% of meteorites are attracted by magnets. 5 Chondrites: Most of the meteorites are chondrites (90% of the total), and a large number of these meteorites are millimeters in size.

6 Specific gravity: The specific gravity of the iron Yuhuiming meteorite is 8 grams cm3, which is far greater than the specific gravity of ordinary rocks on the earth. Chondrites also have a heavier weight due to their small metal content.

It's really a meteorite that has to go through the auction process in order to make a high-quality shot.

It's a little similar, but I'm not sure.

Meteorites are divided into two categories: "stony meteorites" and "iron meteorites".

On the surface of a stony meteorite, there are many small bubbles formed by combustion. If you take a closer look, isn't that the case?

Your ** is not clear, can't be seen.

No. There are a lot of stones like yours on the dams on our side.

The determination of meteorites can only be determined by professional comparison of mineral composition, not all stones can be called meteorites, meteorite identification from the appearance of flow lines, air marks, and dissolution shells can not be distinguished, because many rocks on the earth have these characteristics, and there are only two or three national, family-level scientific research institutions that can do meteorite mineral composition comparison in China, such as the national observatory, the national geological bureau, but these scientific research institutions are not tested externally. Most of the so-called non-governmental institutions or individuals that can identify meteorites are not qualified.

Iron Meteor is not a cultural relic, and it is not valuable, it is no problem to buy it for a few hundred yuan to play, but it is ridiculous to be a baby.

Meteorites will fly, yours will not.
