石铁陨石

Iron meteorite

规格说明:长约:26.8cm宽约:19.6cm重量约:8.77kg

Specification: length: 26.8cm wide: 19.6cm weight: 8.77kg

陨石在高空飞行时,表面温度达到几千度。在这样的高温下,陨石表面融化成了液体。后来由于低层比较浓密大气的阻挡,他的速度越来越慢,融化的表面冷却下来,形成一层薄壳叫“熔壳”。熔壳很薄,颜色是黑色或棕色的。在熔壳冷却的过程中,空气流动在陨石表面吹过的痕迹也保留下来,叫“气印”。When meteorites fly at high altitudes, their surface temperatures reach several thousand degrees. At this high temperature, the surface of the meteorite melts into liquid. Later, due to the obstruction of the lower and denser atmosphere, his speed became slower and slower, and the melting surface cooled down to form a thin shell called "molten crust". The molten shell is thin and black or brown. During the cooling process of the molten crust, the traces of air flowing on the surface of the meteorite are also retained, which are called "air marks".


  此铁陨石在陨落地面以前要穿越稠密的大气层,陨石在降落过程中与大气发生磨擦产生高温燃烧后遗留很多痕迹,使其表面发生熔融而形成一层薄薄熔壳,凹陷处有一些泛红的锈迹,清晰明显,上有流线纹,布满致密的小气泡,该铁陨石含多种金属矿物质,极为稀有,非常适合投资和收藏。The iron meteorite passes through the dense atmosphere before it falls to the ground. During its landing, the meteorite rubs against the atmosphere and produces many traces after burning at high temperature. The surface of the meteorite melts and forms a thin molten crust. There are some red rust marks in the depression, which are clear, streamlined and filled with dense small bubbles. The iron meteorite contains a variety of metallic minerals, which are extremely rare and suitable for investment and collection.
