精品推荐—天外之物陨石

大家好，欢迎来到IT知识分享网。

现实版来自星星的你，陨石，由于宇宙的奥秘无穷，这些陨石就成了神秘的代表藏品，外天空 的石头也受热捧，市场上一块小小的陨石价格就已经能堪比黄金了。市场上也有这么一群人，他们是职业陨石猎人，也叫猎星人。在中国，他们的工作便是在深山老林、戈壁荒漠中寻找陨石，并高价出售谋取暴利。寻宝的过程充满险阻，但一夜暴富的故事又不断施加着诱惑。

陨石是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，少数来自月球和火星。陨石根据其内部的铁镍金属含量高低通常分为三大类：石陨石、铁陨石、石铁陨石。而橄榄陨石是石铁陨石中的最稀有最珍贵的一种，全球发现量不到1%左右。

藏品介绍

中文名称：陨石

英文名称：meteorites

规格：一块（3500克）

类别：杂项

品相：美品

这块石陨石外形端正，质感强，比重高，容易收藏保存，陨石历来都是吉祥石，天外来物，“石来运转”寓意美好。我们都知道陨石通过外表识别一般是以熔壳、比重为依据，熔壳是陨石经过高温熔融产生的1mm左右黑色或深褐色壳，这块陨石溶解特征十分明显，且比重很高。

陨石表面蜂窝状融壳极为明显，掉落时与地球撞击，地球的泥沙混入其中融为一体，这是陨石的明显特征，融壳越好价格越高。

可见其具有一定的磁场，与磁铁产生吸附效果，这就是陨石里罕见的石铁陨石，更具磁性的强弱可以判断其金属含量，由此可断定是铁陨石，还是石铁陨石，从外观来看和吸附力来看，符合石铁陨石特征。

陨石是太阳系的“考古”标本，根据对陨石中铀、钍、钾等元素的同位素组成的测定，可以推算出：太阳系元素的年龄为54±4亿年，元素形成后至太阳星云凝聚之间的“间隔年龄” 为1—3亿年，太阳星云开始凝聚是在距今47 亿年前，太阳系中各类陨石凝结的年龄大约是 45—46亿 年，这也可以作为太阳系各行星形成的年龄。由此可见，研究陨石对太阳系演化的年代学的研究有多么重要的意义。 陨石在太阳系茫茫空间运行过程中，有可能由于受到碰撞而破碎，碎片直接暴露在宇宙射线之下，会形成许多种宇宙成因核素。对陨石中各种宇宙成因核素的研究， 可以为我们探讨银河系宇宙射线的成分、能谱，认识宇宙线的长期变化规律，弄清高能核反应的特点，故而，陨石又被称作宇宙空间的天然“探测器”。

可以看见明显的气印，按照传统理论,陨石气印就是没有规律的“拇指印”几何形,而这种“拇指印”也成为了经典的陨石鉴定标准，可见此陨石气印痕迹十分明显，堪称经典，可为陨石气印之典范。

由于这些小天体是以宇宙速度在太空中运行的，远比枪弹、炮弹的行进速度大得多。因此，小天体之间相互撞击所产生的撞击力是很大的。在这种撞击力的作用下，会使小天体之间的撞击面上产生高温高压并使矿物岩石熔融变质而形成熔融体。这种熔融体的形状千姿百态。概括地说，遗留在小天体外表的变质熔融体就是小天体的熔壳、熔坑和熔槽。遗留在小天体内部的变质熔融体就是熔洞壁、熔带。通过对陨石的观察发现，每次撞击建造出来熔壳的厚度一般在一毫米至十毫米之间。

素来陨石就被视为吉祥之石：有时来运转之意，更有天降时运的好兆头，在这个人民币快速贬值的时代，商人更愿意投资稀有品，正所谓千金易得，一宝难求，目前人们追求陨石更胜过钻石，其价值以克计算，更有甚者拿陨石泡茶，来调节人体磁场，达到健身养生的目的。这块陨石外观品相极好，做个底座就能当摆件，观赏价值以及收藏价值极高。

英文翻译：The reality version of you from the stars, meteorites, because of the infinite mystery of the universe, these meteorites have become a mysterious representative of the collection, the stone of the sky is also in hot demand, a small meteorite price on the market has been comparable to gold. There is also a group of people in the market who are professional meteorite hunters, or star hunters. In China, their job is to find meteorites in the remote mountains and Gobi desert and sell them for a huge profit. The process of treasure hunting is fraught with obstacles, but the lure of get-rich-quick stories is constant.

Meteorites are debris from other celestial bodies in the solar system outside the Earth. Most of them come from asteroids between Mars and Jupiter, and a few come from the moon and Mars. Meteorites according to their internal iron and nickel metal content is usually divided into three categories: stone meteorites, iron meteorites, stone and iron meteorites. The olivine meteorite is one of the rarest and most precious stone and iron meteorites, and less than 1% of them are found worldwide.

The collection is introduced

Chinese name: meteorite

English name: meteorites

Specification: One piece(3500 g)

Category: Miscellaneous

Appearance: Beautiful

This stone meteorite has a straight shape, strong texture, high proportion, and is easy to collect and preserve. Meteorites have always been auspicious stones, foreign objects in the sky, and “stone to run” means good meaning. We all know that the appearance of meteorites is generally recognized on the basis of molten shell and specific gravity. The molten shell is about 1mm black or dark brown shell produced by the meteorite after high temperature melting. The dissolution characteristics of this meteorite are very obvious, and the specific gravity is very high.

The honeycomb melting shell on the surface of the meteorite is very obvious. When it falls, it impacts with the earth, and the earth’s sediment is mixed into it, which is the obvious feature of the meteorite. The better the melting shell, the higher the price.

It can be seen that it has a certain magnetic field, and the adsorption effect of magnets, this is a rare stone iron meteorite in the meteorite, more magnetic strength can be determined by its metal content, which can be determined to be iron meteorite, or stone iron meteorite, from the appearance and adsorption, in line with the characteristics of stone iron meteorite.

Meteorites are the “archaeological” specimens of the solar system, according to the meteorites uranium, thorium, potassium and other elements of the isotopic composition of measurement, can be calculated: the age of the solar system elements for 54-400 million, element to after the formation of the solar nebula cohesion between “space age” for the 1, 300 million, the solar nebula began to condense is in about 4.7 billion years ago, all types of meteorites condensation in the solar system is about 45-4.6 billion age, it also can be used as the planets in the solar system formation of the age. This shows how important the study of meteorites is to the chronology of the evolution of the solar system. During the movement of meteorites in the vast space of the solar system, they may be broken by collision, and the debris will be directly exposed to cosmic rays, which will form many kinds of cosmic origin nuclides. The study of various cosmic origin nuclides in meteorites can help us to explore the composition and energy spectrum of cosmic rays in the Milky Way galaxy, understand the long-term change law of cosmic rays, and make clear the characteristics of high-energy nuclear reactions. Therefore, meteorites are also known as the natural “detectors” of space.

Can be seen obvious gas imprint, according to the traditional theory, meteorite gas imprint is no regular “thumb imprint” geometry, and this “thumb imprint” has become a classic meteorite identification standard, visible this meteorite gas imprint trace is very obvious, can be called a classic, can be a model of meteorite gas imprint.

Because these small bodies move through space at the speed of the universe, far faster than the speed of guns and shells. Therefore, the impact force produced by small bodies colliding with each other is large. Under the impact force, high temperature and high pressure will be generated on the impact surface between small celestial bodies, and the molten body will be formed by melting and metamorphism of minerals and rocks. This molten mass comes in many shapes. Generally speaking, the metamorphic molten body left on the surface of a small celestial body is the molten shell, crater and trough of a small celestial body. The metamorphic molten body left in the interior of the small celestial body is the wall of the molten cavity and the molten zone. Observations of meteorites show that each impact creates a molten shell that is typically between one millimeter and ten millimeters thick.

Have meteorites is considered auspicious rock: sometimes for work, more of heaven to be a good one million head, in this era of rapid renminbi devaluation, businessmen are more willing to invest a rare product, is the so-called daughter comes easily, a treasure is hard to find, at present people pursuit of meteorites more than diamonds, its value in terms of g, moreover meteorites make tea, magnetic field to adjust the human body, achieve the goal of fitness regimen. The appearance of the meteorite phase is very good, make a base can be used as ornaments, ornamental value and collection value is very high.
