Its internal silicate mineral content is roughly equal to that of nickel iron alloy. This unique composition combination makes stone iron meteorite occupy a pivotal position in scientific research and collection. The formation of stony iron meteorites is closely related to the early celestial collision events in the solar system. They carry rich cosmic information and are important clues for studying the origin of the solar system, planetary evolution, and the origin of life on Earth. 2、 Characteristics of high-quality stone iron meteorites 1. Appearance features: 1. Molten crust: When meteorites pass through the atmosphere, a thin layer of molten crust is formed on the surface due to high temperature and pressure, usually black or brownish red in color, with rough surface, pores, and melt lines. 2. Airprint: The surface of the molten shell often has air marks of different sizes and shapes, which are generated by the friction between meteorites and atmospheric molecules during high-speed flight. 3. Internal structure: After cutting, it can be seen that silicate minerals are interwoven with nickel iron alloys, forming unique textures and patterns. 2. Physical properties: 1. Density: The density of stony iron meteorites is usually high, generally between 5.5-7.0 g/cm ³. 2. Magnetism: Due to the presence of iron nickel alloys, stony iron meteorites usually have strong magnetism. 3. Hardness: The hardness of silicate minerals and iron nickel alloys is different, which results in certain differences in hardness of pyrite meteorites. 3. Chemical composition: The main components of stony iron meteorites are silicate minerals (such as olivine, pyroxene, etc.) and iron nickel alloys. Silicate minerals are rich in elements such as magnesium, iron, and silicon, while iron nickel alloys are rich in elements such as iron, nickel, and cobalt. 3、 Recommended high-quality stone iron meteorites Name: Natural Premium Olivine Iron Meteorite Appearance: The surface of this meteorite is covered with a thick molten crust, which is distributed with clear air imprints and melt lines, showing the magnificent scene of the meteorite crossing the atmosphere. After cutting open, the interior presents a beautiful texture interwoven with olivine and iron nickel alloy, with a warm color and tempting luster. Composition: The silicate minerals of this meteorite are mainly olivine, rich in elements such as magnesium and iron; The iron nickel alloy is rich in elements such as iron and nickel, forming a unique composition combination. Scientific research value: This meteorite carries rich cosmic information and is an important physical material for studying early solar system collision events, planetary evolution, and the origin of life on Earth. Meanwhile, its unique combination of olivine and iron nickel alloy also provides valuable samples for geological and mineralogical research. Collection value: This meteorite has a complete appearance, exquisite appearance, and high ornamental and collection value. Meanwhile, due to its rarity and scientific value, it has also become a sought after treasure among meteorite collectors. As "extraterrestrial visitors" in the universe, stony iron meteorites not only have extremely high scientific research value, but also are treasures sought after by meteorite collectors. The natural and high-quality olivine iron meteorite introduced above is a rare masterpiece in terms of appearance, composition, scientific research, and collection value. I hope this detailed introduction can help you better understand stony iron meteorites and find your favorite meteorites on the road to collection.
