What color is meteorite and what does it look like?

It must be copper-colored! With a little dark!

Pyrite meteorite meteorite meteorite after the first ** meteorite meteorite has violent friction with the air flow during the fall, resulting in high temperature and high heat resulting in the melting of the meteorite's external elements. Therefore, the edges of high-altitude meteorites are mostly smooth and smooth. The edge of the low-altitude ** or the collision of the meteorite in the process of falling is much sharper, and the edge of the meteorite is much sharper, and even forms a state of neat corners and sharp blades.

Meteorites are usually black, gray, or brown, and individual meteorites are blue, yellow, and red. Glass meteorites are a little more colorful: green, red, yellow, orange, cyan, and so on.

Meteorites have different textures and different colors. White and light-colored meteorites are very rare.

Formation of meteorites

Because meteorites are from outer space, the determination of the authenticity of meteorites requires instrument identification, and the naked eye only has an auxiliary role. Most meteorites come from the asteroid belt between Mars and Jupiter, and a small number from the Moon and Mars. Meteorites can be roughly divided into stony meteorites, iron meteorites, and mixed meteorites of stone and iron.

The average density of meteorites is between 3 and the main component is silicate. Meteorite has a density of , mainly composed of iron, nickel. The meteorite composition is somewhere in between, with a density in between.

Meteorites vary in shape, the largest meteorite is the Jilin No. 1 meteorite, which weighs 1,770 kilograms, and the largest meteorite is the Goba meteorite from Namibia, which weighs about 60 tons.

The crown of Chinese meteorites is the "silver camel" found in Qinghe County, Xinjiang, weighing about 28 tons. More than 40,000 meteorite samples have been collected worldwide, in a variety of styles. They can be broadly divided into three main categories:

Stony meteorites (the main component is silicate), iron meteorites (iron-nickel alloys) and stony-iron meteorites (iron and silicate mixtures).

Summary. The distinction between iron meteorites and iron ore is actually very simple, that is, by the method of elimination, as long as the possibility of iron ore and artificial products is ruled out, the result must be iron meteorites'. Iron ore is easy to distinguish, all iron ore in nature does not contain elemental iron, the composition is iron polyvalent oxides or sulfides, etc., this is the authoritative definition of mineralogy, no one has the qualification and power to overturn it.

Elemental iron will show a silvery-white luster no matter what the situation, and only iron sulfide and mirror iron ore can have a metallic texture, these two iron ores are obviously characterized by cleavage formed by crystallization, which is obviously different from the characteristics of iron meteorites without cleavage, and other types of iron ore have their own unique characteristics for easy identification.

How to distinguish iron meteorites from iron ore.

Magnetite is strongly magnetic, and the crystals are often octahedral and a few are rhomboidal dodecahedron. The aggregate is often dense and block-like, with iron black color streaks and semi-metallic luster.

Hematite is an oxide mineral with Fe2O3 chemical composition and trigonal crystal system. It forms a homogeneous polymorphic form with equiaxed hematite.

The crystals are often plate-shaped; The aggregates are usually flaky, scaly, kidney-shaped, oolitic, lumpy, or earthy. It is reddish-brown, steel-gray to iron-black, and the streaks are cherry red.

Limonite Limonite is a hydrous iron oxide ore that is produced by weathering other ores and is most widely distributed in nature, but it is rare to have large burial deposits.

The chemical composition of pyrite is FeS2, which is the main mineral raw material for the extraction of sulfur and the manufacture of sulfuric acid. Its crystals belong to the equiaxed crystal system. The composition usually contains small amounts of cobalt, nickel and selenium, and has a NaCl-type crystal structure.

There are often intact crystal shapes, which are cubes, octahedrons, pentagonal dodecahedrons and their clusters.

Mirror Iron Ore Chemical Composition: Fe2O3; Shape: trigonal, massive, scaly; Exterior color: steel gray, iron black; streaks: pale red; It is magnetic when burned.

As long as the suspected iron meteorite in your hand is compared with the above iron ore specimens, you can basically identify it as an iron meteorite or iron ore.

1. Formation of meteoric iron

Meteorite refers to the meteorite that falls from the sky to the earth after a long time of interaction with the earth's atmosphere, the surface is oxidized or partially weathered iron-nickel alloy, generally distributed around the crater or buried deep on the surface, in the shape of pig iron or steel, but meteorite is indeed a unique celestial material.

Therefore, the color of meteorite iron is not the same as that of ordinary metal, and it usually has a metallic luster, but the color is darker, and the color of different meteorites will also vary.

2. The color of the meteorite traces

The color of meteorite iron is usually related to related factors such as its composition, surface condition, and the time of the meteorite impact. For example, some nickel-iron minerals will take on different colors due to the different proportions of oxides they contain, and some meteorite surfaces will also be oxidized to give a green color due to the presence of copper.

At the same time, the carbon content of meteorite iron will also affect the degree of protection against oxidation, the higher the carbon content, the more difficult it is to be oxidized, and the closer the color is to metallic yellow.

3. Classification of meteoric iron

According to the composition of meteoric iron, meteorite can be divided into three main categories: mafic meteorite, graphitic meteorite, and mixed meteorite coarseness. Among them, the composition of mafic meteorite is mainly nickel-iron, and the appearance is gray or iron-yellow; Graphitic meteorite is dominated by graphite and is black-gray in color; Mixed meteorite iron is produced by mixing the two, showing a complex color posture stool tassel tone.

4. Application of meteorite

Due to the high pressure conditions and the environment different from the earth's minerals when it is formed, meteorite has unique properties in composition and structure, which is of great significance for scientific research and technology. The main use of meteorite iron is as an ornament and collectible, and in the international market, some high-quality meteorite iron is expensive.

In addition, meteorite can also be made into tools, **, etc., and the effect is especially significant in special environments. It has important value and role in the scientific research of earth materials, the exploration of the solar system and the development of new materials.

Morphological characteristics: many iron meteorites have a corrugated BAI surface, while many stone meteorites have more low fingerprints or air marks on the surface, DAO meteorite samples are generally irregular but have rounded edges, and artificial iron or stainless steel have straight edges or 90° angles.

1. The so-called meteorites are small celestial bodies that enter the atmosphere from outside the earth, most of which are originally asteroids. However, there are also meteorites that are rarely from the Moon and Mars. The members of the small celestial family collide with each other and break up, and if they happen to come near the Earth while floating in space, they will be attracted by the Earth's gravity and begin to fall towards the Earth.

The small ones burned in the atmosphere with a glow, and the ones that didn't fall to the ground. Meteorites turned out to be asteroids, and because of this, it is the most direct and precious material for studying the history of the solar system.

2. On the earth, iron oxides - magnetite and hematite are often recognized as iron meteorites. Simple identification method: take a white porcelain plate and use a rock to carve on the porcelain plate, the white porcelain plate will leave typical streaks, hematite will leave reddish-brown streaks, magnetite will leave gray-black streaks, and meteorites will not leave streaks; And if you can see the internal structure of the fresh rock, the inside of the iron meteorite will be bright silvery-white, while magnetite and hematite do not have this characteristic, black or gray-black, if you are making a standard probe light sheet, in the electron probe test, magnetite or hematite will be ** state.

Iron meteorites, on the other hand, have an atomic iron and a high nickel content, while rocks on Earth contain almost no nickel in an atomic state unless it is synthetic.

Summary. It's not a meteorite, it seems to be iron ore, and there is no cyclone on the cow stone, (referring to the traces of meteorites burning through the atmosphere.)

Could the teacher please show me if this is a meteorite? Or iron ore?

Experts look at meteorite horses? This one is a slice of the one above, and the two in the middle are a stone.

Obviously not, meteorites are cosmic meteors other than the earth that break away from their original orbits or scatter to the earth in pieces, and they are natural solids that fall from cosmic space to a certain place.
