Stone iron meteorite is also called meteorite. It is a rare type of meteorite, accounting for 2% - 4% of the total number of meteorites. The content of iron, nickel and silicate minerals is about the same (30% - 65%). The main minerals are olivine, pyroxene, serpentine and nivalite. Most of them are about 5.5-6 g / cm ^ 3 in density. In metallic Fe Ni Alloys, the nickel content is mostly 12% - 14%, so the Wiedemann structure appears.
There are two types of iron meteorites: Olivine iron meteorite (olivine + metal) and mesolith iron meteorite (olivine + bronopyroxene + metal). However, they have little in common, so it is difficult to classify them. According to the composition characteristics of silicate minerals
① Olivine meteorite iron (type symbol P) is mainly composed of olivine and Fe Ni metal.
② Iron meteorite (m) is mainly composed of plagioclase, pyroxene and iron nickel.
③ The ancient copper lepidoclase meteorite (s) is mainly composed of iron nickel, ancient copper pyroxene and lepidoclase.
"The collection cherishes treats the good guest, dares not package to drill the right lucky." Su Shi, a great literati of a generation, collected tea only for entertaining good friends and guests. He resolutely refused to bribe powerful officials with famous tea at that time. Collection is a hobby of collection, storage, classification and maintenance of items. Love one thing and protect another.
Meteorites are debris from other celestial bodies in the solar system outside the earth. Most of them come from asteroids between Mars and Jupiter, and a few from the moon and Mars. They can be roughly divided into three categories: meteorites, iron meteorites and iron meteorites.
Stone iron meteorite is also called meteorite. It is a rare type of meteorite, accounting for 2% - 4% of the total number of meteorites.
Since ancient times, meteorites have been used to protect people's homes, ward off evil spirits, prosper wealth, protect health, avoid danger, transport and prolong life. Although this collection is not beautiful and has no ornamental value, it is a rare kind of meteorite, and its collection value is far beyond the surface value of meteorites. Each piece of meteorite is unique, and its historical value and scientific research value are rare, which cannot be created by human productivity. In addition, meteorites have the dual value of collection, utilization and scientific research, so that meteorites are favored by many collectors and researchers, and the market price of meteorites is also rising.
