Is this a meteorite for me? Mine is not a meteorite

Meteorite is a stony, iron, or mixed material of stone and iron that has not been burned out of its original orbit or scattered to the surface of the earth or other planets in fragments"Meteorites"。Most meteorites come from the asteroid belt between Mars and Jupiter, and a small number from the Moon and Mars.

To determine whether a sample is a meteorite, the following aspects can be considered:

1. Molten crust: The meteorite has to pass through the dense atmosphere before falling to the ground, and the meteorite rubs with the atmosphere during the landing process to produce high temperatures, causing the surface to melt and form a thin layer of molten crust. As a result, the surface of the newly landed meteorite has a black molten crust with a thickness of about 1 mm.

2 Surface air marks: In addition, due to the interaction between the meteorite and the air current, the surface of the meteorite will also leave many air marks, like finger prints.

3 Internal metals: Iron meteorites and stony iron meteorites are composed of metallic iron, which has a high nickel content (5 10). Chondrites also have metal particles inside, and fine metal particles can be seen on fresh fracture surfaces.

4 Magnetism: Because most meteorites contain iron, 95 meteorites can be attracted by magnets.

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

Summary. You can look at the magnetism of meteorites, stony meteorites have low iron content and weak magnetism, while stony-iron meteorites and iron meteorites are highly magnetic.

Hello, what kind of meteorite.

You can look at the magnetism of meteorites, stony meteorites have low iron content and weak magnetism, while stony-iron meteorites and iron meteorites are highly magnetic.

Or see if there are any traces that resemble finger prints.

It is formed by the interaction of meteorites and atmospheric currents.

A little bit of magnetism.

There are also nail lines.

If it is a real meteorite, ** at 800-2000 grams, it must be well preserved.

Well. You connect me with a buyer, and the benefits will be great after the success of the matter.

There are very few such meteorites in the country, but you can try your luck at the antique market or antique shops.

I can't see it clearly, but it is a vitreous substance shown in **, and it is estimated that it is not a meteorite (characteristics such as the characteristics and size of the shell). If you have to quickly and easily determine what it is, go to the laboratory to test the nickel content, and the nickel content is between 3-10%, which is estimated to be a meteorite.

See Wikipedia.

Regarding the identification method of meteorites, enter "meteorite" in the encyclopedia (or search for the first place in "meteorite encyclopedia"), find the two paragraphs of "identification method" and "potential meteorite characteristics", and carefully examine whether there are those characteristics described.

Haha, can't you just find an instrument to test.

You'll have to find an expert to determine this.

It doesn't look like much. Is it magnetic?

A meteorite is a hard substance formed by dust in space around a condensation nucleus, and when it is captured by the gravitational pull of a planet and enters the atmosphere of that planet, it will burn violently, which is a meteor; When a meteor falls to the ground and does not burn up, it is called a meteorite.

Stones, on the other hand, are formed by the cooling of magma inside the planet, which is not the same as the nature of meteorites.

Size: Meteorites range in size from a few centimeters to a few feet in diameter.

Shape: Meteorites are rarely round, and are generally irregular with rounded corners.

Weight: Due to the nickel-iron alloy contained in meteorites, they are usually heavier than the average rock of the same size on Earth. The metal content and nickel content of the earth's rocks and earth's materials formed by natural conditions are much lower than those of meteorites.

Color: Before the meteorite falls to the ground, it has to pass through the dense atmosphere, and during the landing process, it rubs with the atmosphere to produce high temperatures, causing its surface to melt and form a thin layer of molten crust. As a result, meteorites that have just fallen have a black molten shell on their surface, about 1 mm thick.

However, as time passes, the weather-hardened meteorites will slowly turn iron-brown, and the molten crust on the surface will disappear completely.

Surface characteristics: Most meteorites have a smooth and non-porous surface, but a few meteorites will show thin lines or "fingerprints" on the surface. These "fingerprints", known as surface air marks, are the result of the melting and ablation of different internal substances as a meteorite passes through the atmosphere, like fingerprints pressed by a finger.

Internal characteristics: Most stony meteorites, especially ordinary stony meteorites, can see fine metal particles in sections, sections or parabolic planes. In addition, small round spheres can be found in most stony meteorites.

Iron meteorites, on the other hand, are almost entirely made of metal, and stony-iron meteorites contain half of the metallic substance.

Visually, it is a limestone river pebble and water stone, and there is no meteorite performance.

Limestone, referred to as limestone, is a carbonate rock with calcite as the main component. Sometimes it contains dolomite, clay minerals and detrital minerals, gray, gray-white, gray-black, yellow, light red, brown-red and other colors, the hardness is generally not large, and there is a violent chemical reaction with dilute hydrochloric acid. It belongs to sedimentary rocks according to its genetic classification.

Mineral particles and crystal structures are rare, and the surface is smooth and small granular. The hardness varies, and some dense limestone can be polished. In modern industry, limestone is the main raw material for the manufacture of cement, lime and calcium carbide, and is an indispensable flux limestone in the metallurgical industry.

Water flushing stone, produced in the place of rivers in various places, there are many varieties, its appearance is mostly round and shaped, the surface is fine and smooth, and the stone pattern has bands, stripes, spots, ripples and irregular curved bands. The biggest feature of the water stone is that the pattern is gorgeous and colorful, the stone is solid, mostly black, yellow, blue-gray, among which the pattern stone is more precious. Water stone is known for its quality, color, shape, pattern and unique charm and appearance, the variety makes people taste endlessly, some of the water stone is larger, but large but not stupid, in the garden to do more solitary stone placement, suitable for lettering, it is the preferred landscape stone material for the construction of artificial rivers in the garden, scenic spots, villa areas and other water stone landscapes.

The determination of meteorites requires professional comparison of mineral composition to determine, not all stones can be called meteorites, meteorite identification from the appearance of flow lines, air marks, dissolved shells can not be distinguished, because many rocks on the earth have these characteristics, only two or three national scientific research institutions can be compared with meteorite mineral composition in China, such as the National Astronomical Observatories and the National Geological Administration, 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.

Meteorites have scorch marks on the outside; High density and heavy mass; The most prominent feature is the high iron content, with a strong magnetic magnet close to a slight adsorption phenomenon, your stone meets the above, if it does, congratulations, collect it.

Visual inspection is not very reliable, and an authoritative agency is still needed. It is recommended to take it to an authoritative institution for testing.

Visually it is a pine oreinite, not a meteorite.

Turpentinite, is an acidic vitreous volcanic rock. Usually contains a little speckle crystal, moisture content 4% 10%. It has a pine resin luster (similar to bituminous luster) and shell-like fractures, and may be monochromatic, striped, or spotted in color.

Dense block, sometimes seen in stone bubble structure. Pine resin can be used as a raw material for the manufacture of expanded perlite. It is commonly found in areas of acidic volcanic rocks.

Together with obsidian, perlite, and pumice, it is collectively referred to as acid volcanic glass rock.

It looks like it's a meteorite...
