藏品鉴赏玻璃陨石

　　玻璃陨石是某种石陨石降落过程中融化的液质冷却后的产物，是太空天体在陨落到地球大气层时，产生熔融第二次结晶的物质。由于组成的成份不同，其颜色也各不相同。极品玻璃陨石有两大特点：一是玻陨石整体完整，陨坑、气流痕、熔流痕、熔壳等外观明显；二是由稀有元素或地球上没有的元素而组成的玻陨石。英国生物学家达尔文1844在澳大利亚获得一块钮扣状玻璃质石块，以后在世界范围内这种类似玻璃质石块通称为＂玻璃陨石＂。它是一种天然玻璃物质。由于外观似黑曜岩，故又称似黑曜岩。但两者的成分、结构都不同。大多数玻璃陨石的形状与熔融溅射物的形状相似，有球状、细长状、哑铃状、液滴状、钮扣状和不规则的块状等。它成群地撒落在大陆上或海底沉积物中。
　　Glass meteorite is the product of the cooling of the melting liquid during the landing process of a certain meteorite. It is the second crystallization of the melting material produced by the space object when it falls into the earth＂s atmosphere. Because the composition is different, the color is also different. There are two main characteristics of top-grade glass meteorites: one is the integrity of the whole glass meteorite, the appearance of craters, air traces, melt traces, molten crust and so on is obvious; the other is the glass meteorite composed of rare elements or elements not found on the earth. British biologist Darwin obtained a button-shaped glass block in Australia in 1844, which was later known worldwide as ＂glass meteorite＂. It is a natural glass substance. Because it looks like obsidian, it is also called obsidian. But their composition and structure are different. Most of the glass meteorites are spherical, slender, dumbbell-shaped, droplet-shaped, button-shaped and irregular massive. It is scattered in groups in continental or submarine sediments.
　　长期以来，世人们对流星有着美好不一的传说和赞誉，当流星拖着美丽的弧光的划向天际时，有些人们往往会心中默默许下美好的愿望。很多文人墨客更是将流星入句，也因此人们对玻璃陨石这种特殊的陨石有着美丽的向往和收藏的喜好，同时也丰富了知识，拓宽了藏友的眼界。
　　For a long time, people all over the world have a wonderful legend and praise of meteors. When meteors drag beautiful arcs toward the sky, some people often tacitly agree with the good wishes in their hearts. Many literati and Mohists put meteors into sentences, so people have a beautiful yearning for glass meteorite, a special meteorite, and a preference for collecting it. At the same time, it enriches knowledge and broadens the horizons of Tibetan friends.
　　陨石由于其来源的特殊性，已经成为了与邮票、珠宝、字画、钱币等比肩的极具收藏价值的珍品。陨石在全球的价格来看，目前玻璃陨石的价格堪比钻石，陨石收藏逐渐深得藏友心，并且由于它的珍贵和稀少，更是让它成为收藏界的天宠。
　　Because of the particularity of its origin, meteorites have become treasures of great collection value comparable to stamps, jewelry, calligraphy and painting, coins and so on. At present, the price of glass meteorite is comparable to that of diamond in the global price. Meteorite collection has gradually won the hearts of collectors, and because of its preciousness and rarity, it has become the favorite of the collectors.
