精品鉴赏石陨石

　　此陨石重量30kg，为罕见品相完整的石陨石，整体形状极佳，陨石肌肤表面颜色以棕色色为主。陨石肌肤表面呈现自然的熔流纹，方向一致少量的熔流槽与众多的熔流线痕迹。有陨石坠落时形成头尾方向相一致的定向特征。陨石肌肤前端有明显的冲(撞)击小熔坑，气印明显。
　　陨石是指来自地球以外太阳系其他天体的碎片，绝大多数来自位于火星和木星之间的小行星，也有部分来自月球和火星。全世界已收集到较多的陨石，石陨石主要成分是硅酸盐。
　　陨石形状不规则，形态多种多样，个体大小不一。陨石表面一般都有很薄的黑色或深褐色的熔壳，陨石熔壳层是指在大气层内陨石降落过程中由于高温使表面熔化，后来在速度降低时冷却凝固而成，陨石在大气层内坠落与高温气流相互作用烧蚀后会在表面熔壳上留下许多自然肌理特征。陨石的初步感观识别主要以目测观察其是否具有陨石应该有的特点，即外部的熔壳层、气印痕、熔流线等;破损处是否有球粒，金属斑点等;具有似波纹状的表面，熔流纹或气印，黑色或深褐色熔壳等自然肌理特征来识别陨石。
　　其形状规整，具有形状精美的陨石，成色鲜艳，表面熔浆壳细密可见，再加上含少量金属成分，且不带磁性，能确定为石陨石，如此大的陨石目前在全球实属罕见。
　　最近十年，随着陨石知识的日益普及，想收藏的不断增多，奇货可居，国内叫价有时甚至远高于国际价格。世界上众多的博物馆和研究机构也对陨石充满了极大的兴趣，一直致力于对其所处星体和时代的研究，进一步促进了陨石经济价值的提升。目前陨石市场上，各类陨石受追捧，根据陨石的主要成分不同，价位也不同，陨石的科学研究价值高，数量罕见稀少，升值潜力无限，值得收藏。科研人员可以通过研究这些陨石对早期宇宙了解更多，科研价值极高，真正的一石千金。
　　英文翻译：
　　The weight of this meteorite is 30kg, which is a rare stone meteorite with complete phase. The overall shape is excellent, and the surface color of the meteorite skin is mainly brown. The surface of the meteorite skin presents natural flow lines, with a small amount of flow grooves and numerous trace of flow lines in the same direction. When meteorites fall, they form the same directional characteristics in the direction of the head and tail. The front end of the meteorite skin has obvious impact (impact) small crater, and the gas mark is obvious.
　　Meteorites are debris from other celestial bodies in the solar system outside the earth. Most of them come from asteroids between Mars and Jupiter, but some also come from the moon and Mars. More meteorites have been collected all over the world. The main composition of stone meteorites is silicate.
　　Meteorites are irregular in shape, perse in form and different in size. Meteorite surface usually have very thin black or dark brown fusion crust, meteorite fusion crust layer is to point to in the process of the atmosphere within the meteorite landing because of the high temperature melt surface, then cooling solidification, when reduced speed meteorites falling within the atmosphere interact with high temperature air after ablation in many natural surface fusion crust texture features. The primary perceptive identification of meteorites is mainly to observe visually whether they have the characteristics that meteorites should have, that is, the outer molten shell layer, gas imprint, molten flow line, etc.; Whether there are spherules or metal spots in the damaged area; It has corrugated surface, molten flow or gas mark, black or dark brown molten shell and other natural texture features to identify meteorites.
　　Its shape is regular, with the shape of a beautiful meteorite, bright color, the surface of the molten shell is fine visible, coupled with a small amount of metal composition, and no magnetic, can be determined to be a stone meteorite, such a large meteorite is currently rare in the world.
　　In recent ten years, with the increasing popularity of meteorite knowledge, the increasing number of people want to collect, and the rare goods are available, the domestic price is sometimes even far higher than the international price. Many museums and research institutions in the world are also full of great interest in meteorites, and have been committed to the study of the stars and times in which they are located, which further promotes the improvement of the economic value of meteorites. At present, on the meteorite market, all kinds of meteorites are sought after. According to the main composition of meteorites, the price is different. The scientific research value of meteorites is high, the number is rare and rare, and the appreciation potential is infinite, which is worth collecting. Researchers can learn more about the early universe by studying these meteorites, which are of high scientific value and are truly priceless.
