铁质流星坠落的神秘之石

铁的开发与利用，对于推动人类文明进程起到了极其重要的作用，不仅促进了社会生产力，也提高了战斗力。在冷兵器时代，谁先于对手掌握铁器，谁就是那个时期的战斗民族，比如西亚地区最早发明冶铁术和使用铁器的古赫梯人，就曾凭着这项技术，让古巴比伦、古埃及两大文明跪着唱征服。特别有意思的是，当时古埃及并不是完全没有冶铁术和铁器，只不过他们的铁是来自外太空的陨铁，因稀有神秘而被奉为神物，所以当看到赫梯人全员手持神装时，大概就像《洛基》第一季里，洛基看到时间变异管理局某普通员工那满满一抽屉的无限宝石一样，三观都被震得稀碎吧！不仅是古埃及，

世界上其它地区的人类文明最早接触和使用到的铁也是陨铁。所谓陨铁，其实是陨石中的一类，根据内部成分及含量高低，陨石通常可以分为三类：铁陨石、石铁陨石及石陨石，陨铁就是铁陨石，主要由铁、镍金属单质矿物组成，含量95%以上；石铁陨石中铁、镍含量低一些，在30%—65%之间；石陨石则含量更少，甚至不含任何金属成分，较常见的玻璃陨石就属于此类。相比之下，铁陨石是比较少见的，仅占目前发现陨石总数的3%左右，由于稀有且来自天外，包括古埃及人在内的众多文明或是怀着敬畏之心将之视为神赐之物，或是认为其中含有地球上不存在的神奇成分，因此赋予了它超自然的属性，甚至现代也常常出现在武侠及奇幻类文学、影视作品中，作为神兵利器或者能让人逆风翻盘的神秘力量。不过，这些人为赋予的力量和意义也并非空穴来风，陨石的确具有毁天灭地的威力：当巨大的陨石落在地球上，带来的可不是“让你的泪落在我肩上”的浪漫，而是极其严重的灾难，就像6500万年前那样。而铁陨石由于铁含量极高而杂质少，在人类全面进入铁器时代，发展出高温冶炼的技术之前，是提取铁的不二选择，而由于铁在结实程度方面吊打当时主流的铜制兵器，陨铁出品必属神兵的概念自然就深入人心了。

此外，虽然并没有地球上不存在的神奇成分，但在地壳中的铁都是化合物形态，以单质形态存在的铁，只能在铁陨石中找到。现在，我们可以从很多含铁矿物中获得铁这一重要资源，因此用铁陨石来炼铁不能说是奢侈，只能说是暴殄天物，因为它们经历并记录了星系演化、星球起源等许多珍贵信息，具有极高的科研价值。

The development and utilization of iron has played an extremely important role in promoting the process of human civilization, not only promoting social productivity, but also improving combat effectiveness. In the era of cold weapons, the people who mastered iron weapons before their opponents were the fighting nations in that period. For example, the ancient Hittites, who first invented iron smelting and used iron weapons in Western Asia, used this technology to make the two civilizations of ancient Babylon and ancient Egypt kneel and sing conquest. It is particularly interesting that at that time, ancient Egypt was not completely free of iron smelting and iron tools, but their iron was meteorite iron from outer space, which was worshipped as a god because of its rarity and mystery. So when we saw all Hittites holding divine costumes, it was probably like that in the first season of Rocky, Rocky saw a drawer full of infinite gems from an ordinary employee of the Time Variation Administration, and the three views were shattered! Not only in ancient Egypt, but also in other parts of the world, human civilization first contacted and used meteorite iron. The so-called meteorite is actually a type of meteorite. According to the internal composition and content, meteorites can generally be divided into three types: iron meteorite, stone iron meteorite and stone meteorite. The meteorite is an iron meteorite, mainly composed of iron and nickel metal simple minerals, with the content of more than 95%; The content of iron and nickel in siderite is lower, ranging from 30% to 65%; The content of stone meteorites is less, and even does not contain any metal components. The more common glass meteorites belong to this category. In contrast, iron meteorites are relatively rare, accounting for only about 3% of the total number of meteorites found at present. Because they are rare and come from outside the sky, many civilizations, including ancient Egyptians, regard them as divine gifts with reverence or believe that they contain magical elements that do not exist on the earth, so they are endowed with supernatural attributes. Even modern times often appear in martial arts and fantasy literature, film and television works, As a magic weapon or a mysterious force that can make people turn against the wind. However, the power and significance given by these people are not groundless. Meteorites do have the power to destroy the sky and the earth. When huge meteorites fall on the earth, what they bring is not the romance of "letting your tears fall on my shoulder", but an extremely serious disaster, just like 65 million years ago. However, iron meteorites, because of their extremely high iron content and few impurities, were the best choice for extracting iron before human beings entered the Iron Age and developed high-temperature smelting technology. As iron hung the mainstream copper weapons at that time in terms of the degree of solidity, the concept that meteorite products must belong to divine weapons naturally became popular. In addition, although there is no magic ingredient that does not exist on the earth, iron in the crust is in the form of compound. Iron in the form of simple substance can only be found in iron meteorites. Now, we can obtain iron as an important resource from many iron bearing minerals. Therefore, using iron meteorites to make iron is not a luxury, but a waste of time. Because they have experienced and recorded many precious information such as the evolution of galaxies and the origin of stars, they have high scientific research value.
