这是天下上的石陨石雨。其时共网络到陨石标本138块，碎块3000余块，总重2616公斤。其中的一块陨石吉林1号陨石攻击地面造成蘑菇云状烟尘，而且砸穿冻土层，形成一个6.5米深，直径2米的坑。这块陨石重达1770千克，属于H球粒陨石，该陨石呈棕玄色，上有气印。这也是天下重的石陨石。一号陨石溅起的碎土块远达150米，造成的震惊相当于1.7级地 震，这个吉林陨石雨录下来，使得吉林陨石雨的陨落有了准确的时间记录：1976年3月8日15时2分36秒。 我国在十几年前，铁陨石还不被太多人知道，其价值还不太高，铁陨石交流只在一小部分群体当中发生，那时铁陨石的来源多出自陨石富集区或国内的有陨石坠落的地方，铁陨石收藏群体多以求真务实纯爱好收藏为主。他们能够脚踏实地的去学好一门收藏，也能够翻山越岭的去寻找铁陨石。
陨石珍藏圈的日益扩大，加之其十分有数，让陨石在全球的价 格，从原来的几美元每磅，攀升到现在堪比钻石的巨额数字。凭证内部铁镍金属含量崎岖，陨石通常分为三大类：石陨石、石铁陨石、铁陨石。绝大多数陨石来自位于火星和木星之间的小行星。它们含有地球上不常见的矿物组合，或者地球上没有的球粒结构，通过研究陨石可以获得对太阳系的物质起源、组成和演化的熟悉。国际市场上，陨石的交易价 格很高。一样平常通俗的陨石样品每公斤几万到几十万美元，而像火星和月球这样的珍陨，每公斤数万万美元。纵然很一样平常的玻璃陨石也价值不菲。
In China more than a decade ago, iron meteorite was not known by too many people, and its value was not too high. The exchange of iron meteorite occurred only in a small group of people. At that time, the source of iron meteorite was mostly from the meteorite enrichment area or domestic Where there are meteorite falls, iron meteorite collection groups mostly focus on truth-seeking, pragmatic and pure hobby collection. They can learn a collection down to earth, and they can find iron meteorites across the mountains.
This is the stone meteorite rain in the world. At that time, there were 138 meteorite specimens, more than 3,000 fragments, and a total weight of 2616 kg. One of the meteorites, Jilin No. 1 meteorite attacked the ground, causing mushroom cloud-like smoke and dust, and smashed through the frozen soil layer, forming a 6.5-meter deep pit with a diameter of 2 meters. This meteorite weighs 1770 kilograms and belongs to the H chondrite. The meteorite has a brownish black color and is imprinted on it. This is also a heavy stone meteorite. The fragmented soil splashed by Meteorite No. 1 is as far as 150 meters, and the shock caused is equivalent to a magnitude 1.7 earthquake. This Jilin meteorite rain recorded the accurate time record of the fall of Jilin meteorite rain: March 8, 1976 15 Hours 2 minutes 36 seconds.
Meteorites are small celestial bodies that enter the atmosphere from outside the earth, and most of them are originally asteroids. However, there are very few meteorites from the Moon and Mars. The members of the small celestial body collide with each other and then break up. In the era of cosmic space floating, if they accidentally come around the earth, they will be attracted by the gravity of the earth and land on the earth first. The small ones burned with light in the atmosphere, and the ones that did not burn fell to the ground. Meteorites turned out to be asteroids, and because of clouds, they are a direct precious material for studying the history of the solar system.
Meteorites are human beings who are directly familiar with the precious and precious physical specimens of the stars in the solar system, and they are extremely valuable. Most meteorites have no or unusual mineral combinations on the earth, and traces of high-speed combustion through the atmosphere. As for the astronauts who landed on alien planets, such as the moon, what they brought back was not called meteorites. It will be called lunar ore. According to a 10-year inspection by Canadian scientists, there may be more than 20,000 meteorites falling on Earth every year. Since most meteorites fall in inaccessible areas such as oceans, wild grasses, forests, and mountains, the number of hand meteorites discovered and networked is only dozens a year. Most of them fall from the sky and have different shapes.
The market price of iron meteorite is almost the same as that of gold. Subsequently, the iron meteorite continued to appreciate at an annual growth rate of 30% to 50%. Today, the most common iron meteorite can also be sold for 500-600 US dollars per gram, and rare iron meteorites can reach 3000-6000 US dollars per gram. This price has far exceeded gold. If the constituent material of an iron meteorite is inferred from Mars, the value of the iron meteorite will soar.
Since 2005, there has been a boom in meteorite collection in China. During the seven or eight years, not only did the price of meteorites soar, but the domestic meteorite collection market was gradually taking shape. Four or five years ago, the economic value brought by meteorites was not well known. "No one knows, no thoughts, no question, no attention", in the nineties of the last century, there were only about 200 people involved in the meteorite trade in the world, and more than 10,000 people have joined it now. In recent years, the value of the auction market has increased, and buyers are competing with such great interest from outsiders.
The value of meteorite is closely related to many factors. This is a concrete manifestation of a comprehensive factor, not that meteorites have high value. Specific analysis of specific problems, especially meteorites. When lovers favor certain meteorites, the value of such meteorites will rise; when lovers feel that a certain type of meteorite is monopolized and considered to be manipulated, this type of meteorite may not be interested. Everything depends on time, place and conditions. In this sense, the value of meteorite is relative. At the same time, the value of meteorite is also changed by the change of supply and demand. Long-term participation in tracking can grasp the market dynamics, and the stock market must pay close attention to correct judgment.
The increasing size of the meteorite collection circle, combined with its very large number, has made meteorites' global prices rising from a few dollars per pound to a huge number now comparable to diamonds. The content of iron and nickel in the voucher is rugged. Meteorites are usually divided into three categories: stone meteorite, stone iron meteorite, and iron meteorite. Most meteorites come from asteroids between Mars and Jupiter. They contain unusual combinations of minerals on the earth, or spherulite structures that are not on the earth. By studying meteorites, you can get familiar with the material origin, composition and evolution of the solar system. In the international market, the transaction price of meteorite is very high. Meteorite samples are as common as tens of thousands to hundreds of thousands of dollars per kilogram, while precious meteorites like Mars and the moon cost tens of thousands of dollars per kilogram. Even ordinary glass meteorite is valuable.
In the 90s of the last century, there were only nearly a hundred people involved in the meteorite trade in the world, and now the number of experts, likeers, and researchers who have joined the meteorite auction collection has increased to tens of thousands. The rapid increase in the number of people led to the skyrocketing of the value of Shitie Meteorite in nearly two decades. The value-added ratio from a few dollars per gram to nearly ten thousand yuan per gram far exceeded gold and diamonds.
