How to identify the authenticity of meteorite jade, how to identify the authenticity of meteorite

Meteorite jade fresh words to tell you simply.

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.

Hello dear, how to identify the authenticity of meteorites: methods for identifying meteorites: 1. Appearance, the appearance of meteorites has air marks of different sizes, and if there is no one, it may be fake; 2. Specific gravity, the specific gravity of meteorites is larger, there is a sense of weight in the hand, and the hand of the fake stone is light; 3. Magnetism, meteorites have a certain degree of magnetism, which can attract magnets; 4. Smell, meteorites have a special taste, which ordinary stones do not have.

The surface of natural meteorites will form many air marks of different sizes, and there are also many raised parts, which are distributed in irregular shapes; Whereas, the surface of the fake meteorite has almost no air marks, and the raised parts are flaky. The density of the meteorite is around the right, and it contains a small amount of metallic substances inside, with a large specific gravity. The density of the fake meteorite is small, and the feel will be much lighter. Meteorites contain a small amount of metallic substances, mainly iron, which has a certain magnetism and can easily attract magnets. However, there is no metallic substance in the inside of the fake meteorite, there is no magnetism, and it cannot attract magnets.

Identification by smelling the smell, generally no matter how long the meteorite has fallen, when it encounters moisture in the air, it is easy to produce a special burnt smell, like a burnt smell, and ordinary stones will not have this smell.

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. Further detection is done with a magnetometer or magnet. The specific detection method is (magnetometer detection, which will not be repeated here) - tie a small piece of magnet with one end of a thin wire about 10 cm long, pinch the other end of the thin wire with your hand, and then slowly approach the object to be measured to detect whether it is magnetic.

This has the advantage of avoiding the miscalculation of some stony meteorites with a low metal content because their magnetic properties are not obvious.

Hello. In the pro.

The first is visual inspection.

The main aspect of observation is to see whether Yuchun has the characteristics that a meteorite should have, that is, the external molten shell, air seal, molten flow line, etc.; Whether there are pellets, metal flashes, etc. at the damage of the broken trip; Whether there are pellets, metal flashes, Vickers phases, etc. on the section surface. In addition, it is necessary to compare it with the known "meteorite-like earth rocks".

The second is magnetic measurement verification.

Further detection is done with a magnetometer or a magnetograph. The specific detection method is (magnetometer detection, which will not be repeated here) - tie a small piece of magnet with one end of a thin wire about 10 cm long, and the state judgment uses a manual to pinch the other end of the thin wire, and then slowly approach the object to be measured to detect whether it is magnetic. This has the advantage of avoiding the miscalculation of some stony meteorites with a low metal content because their magnetic properties are not obvious.

The above two aspects can basically be determined to be true or false, if you are not assured, then you have to cut and electron probe measurement, this is more troublesome Wu Zhenli is generally not easy to do, and it is easy to damage the complete cavity of the meteorite.

In the case of an electron probe, it is necessary to specifically determine the chemical and petrological composition of the fiber it contains, and to establish a letter to determine the classification of the meteorite it inspires, such as H5, CO3, IIB, and so on.

Summary. Looking at the molten crust, the surface of the true meteorite will have a black molten crust with a thickness of about 1 mm.

Looking at the molten crust, the surface of the true meteorite will have a black molten crust with a thickness of about 1 mm.

True meteorites have many air marks on the surface that resemble fingerprints, which are formed by the interaction between meteorites and atmospheric currents.

Measuring magnetism, stony meteorites have low iron content and weak magnetism, while stony-iron meteorites and iron meteorites have strong magnetism.

Chondrites: Most meteorites are chondrites (90% of the total), and these meteorites contain a large number of millimeter-sized silicate spheres called chondrites. Round chondrites can be seen on the fresh fracture surface of chondrites.

1. Look at the molten shell.

To identify the authenticity of a meteorite, you can look at the molten shell, which refers to a thin black shell with a thickness of about 1 mm on the surface of the meteorite. The molten crust is formed by the high temperature generated by the meteorite passing through the atmosphere, which causes the surface to melt into liquid, and then cools down due to the blockage of the dense atmosphere at the bottom.

2. Look at the air mark.

In addition, the authenticity of the meteorite can also be identified by looking at the air mark, the melt shell of the meteorite during the cooling process, the traces of air flow blowing on the surface of the meteorite are also preserved, this trace is called "air mark", the shape of the finger print left by finger pressing.

3. Weigh the weight.

Meteorites can also be identified by weighing, most of the real meteorites contain certain iron, nickel and other metal elements, its specific gravity is much larger than that of ordinary rocks, so the weight of the former will be greater compared with meteorites and rocks of the same volume.

The determination of meteorites can only be determined by professional comparison of mineral composition, not all stones can be called meteorites, meteorites can not be distinguished from the appearance of flow lines, air marks, and crusts, because many rocks on the earth have these characteristics, if your sample has the following characteristics, it can be considered whether it is a real meteorite.

First, look at the sample to see if there is a black molten shell.

2.Whether it is a dense solid or not.

3.Whether it is heavier than a normal stone of the same size.

4.Whether you can be attracted to a magnet.

5.Whether it is composed of metal or specks of metal can be seen on the crushed, cut or polished surface of the sample.

There are three main ways to identify meteorites: 1. Looking at the molten crust, there will be a layer of black molten crust with a thickness of about 1 mm on the surface of the true meteorite; 2. There will be many air marks on the surface of the meteorite similar to finger prints, which are formed by the interaction between the meteorite and the atmospheric current; 3. Magnetic measurement, stony meteorites have low iron content and weak magnetism, while stony-iron meteorites and iron meteorites have strong magnetism.
