Characteristics of meteorites:
1. Shape: mostly round or oval, like masonry.
2. Surface characteristics: The surface is covered with pits of different sizes and depths, a bit like the dissolution surface of limestone. The fresh ones have molten crusts and a black surface layer of about one millimeter or more, made of glass or Cryptocrystalline layer. There are often shallow and long air marks or mother and child marks (which may be lost if exposed to strong oxidation). Some are "surrounded" by sulfate epiphytes.
3. Specific gravity: Iron meteorites contain more than 95% iron and nickel, and their specific gravity is generally greater than 8 grams per cubic centimeter. Stone meteorites are also heavier than ordinary rocks.
4. Because it contains iron and nickel, it mostly exists in the form of natural metals and has some special metal mineral combinations, such as: ironite, nickelite, troilite, troilite, troilite, Oxygen iron, meteorite iron-nickel ore. (These require indoor identification) There are no hydrous minerals.
5. Structural characteristics: Most of them are chondrite meteorites. When using a 10x magnifying glass in fresh sections, you can usually see round chondrules, similar to fish roe, which are filled with silver-gray metal minerals, iron meteorites or After the ironstone meteorite is cut and polished, it is etched with dilute nitric acid and alcohol, and a network pattern composed of flake or plate-like grainstone and nickelstone crystals can be seen. It is called the Vespa stool structure. This is the iron-nickel phase that is uniformly molten at high temperatures. It is formed by melting in the unique slow cooling of the universe.
6. Magnetism: Because meteorites contain 20% to 90% iron, they are often magnetic. When searching in the wild, it is best to bring a magnet (except for severely weathered ones)
7. Color of streaks: When rubbed on a white unglazed porcelain plate, most of them have no or only light gray (melted crust) Streak colors, while the streak colors of gallinite and hematite, which are abundant on Earth, are black and peach (reddish-brown) respectively.
So it’s not a meteorite, otherwise meteorites would be everywhere
