陨石也称“陨星”，是地球以外脱离原有运行轨道的宇宙流星或尘碎块飞快散落到地球或其它行星表面的未燃尽的石质、铁质或是石铁混合的物质。
俗话说的好，“外来的和尚会念经”，而外来 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。

看陨石的熔壳和气印特点
陨石的熔壳大多是灰黑色，这是陨石穿越太空和大气层燃烧碳化的必然熔貌，熔壳一般有一毫米左右也有的因为燃烧很充分比较厚。而气印是大气对陨石的雕琢印迹，陨石的气印不同于一般石头的风蚀和水蚀包括岩浆的冷却洞孔那样的柔弱质感，陨石的气印更多表现为指甲纹捏塑的形态或流线型特征，质感相对硬朗和阳刚。在陨落过程中强大的冲击波打造了陨石的阳刚之痕，简单说地球岩石表面痕迹显柔，而陨石气印大都显刚，这是基本的质感特征。当然高空爆炸和低空爆炸陨石很多不具备熔壳气印的特点，关键我们要去细心地观察。从陨落过程来看陨石的陨落主要分为～定向、反转和旋转三大类别，在猎陨过程中我们发现定向陨石的气痕大多朝一个方向熔融，形态多有棱角和边线。反转陨石则会出现多样气印，在形态上被大气打造的比较全面些，相貌多样边缘多弧形和椭圆形态比较多。旋转陨石在旋转陨落过程中多表现为圆球形和螺旋扭转纹路。当然陨石在太空划落的运动轨迹大都是多样的发生，所以我们变通的去判断陨石非常重要。
陨石表面具有极为明显的融壳，而且气印非常明显，经地质大学研究，掉落在地球上的陨石依然会保持在本体星球的特征，陨石表面颜色发红为少见的陨石，在陨石地位排行第二，价值仅次于水星陨石。
从陨石熔壳的缺口处看内部相貌判断。
陨石质地因为普遍含有硅酸盐和镍元素，最基本的方法是从陨石的落地破损处看有没有星星点点闪光折射，如果在太阳光下离近可以看到状闪亮，那基本可以断定是硅酸盐的晶体折射与镍原素的闪亮，从这些内部相貌特征我们也可以判断是不是陨石。当然陨石种类的多样性和我们已知经验的有限性不可能一概而论，我们则需要不断的充实实战的经验来参照。
从陨石特殊的气质和环境比较来断定。
陨石源于宇宙太空世界有着地球石头不同的特有气质，陨石有着宇宙的能量气场与地球石头质感有着很大区别，特有的视觉能量感使陨石有了不同寻常的石头气质，就如我们看惯了中国人突然看到西方人一般新鲜和异样，陨石具有的由内到外特殊的气场让我们可以感应到一种神秘的能量感。这就是从气质断定的方法。在荒漠、戈壁、山区等地我们如果发现与周围岩石和环境不同的石头就要引起关注，加上我们的经验判断基本就可以断定是不是陨石了。
我们通过常规的地球化学手段，可以得到火星硅酸盐分异的时陨石是被撞击溅出火星的碎块。硅酸盐分异后，放射性核素K-40衰变形成的惰性气体Ar-40会在矿物中累积，从而可以指示硅酸盐的分异时间。但在撞击过程中，惰性气体会逃逸，相当于时钟被重新定时。测定火星陨石的K-Ar年龄，我们可以知道这些陨石什么时候离开了火星。陨石中宇宙成因核素的含量可用来推断陨石在太空中停留的时间，而陨石一旦落入地球，宇宙成因核素的生成停止，我们还可以通过放射性宇宙成因核素的含量来判断陨石是什么时候落入地球。
陨石的新闻可谓是层出不穷，一直报道陨石价格以克来计算，更是炒到五万十万一克，要知道什么样的陨石才有价值，值得投资，相信陨石爱好者都知道一个拳头大小的陨石成交价八千多万，与地球同岁。从图片来看那颗八千多万的陨石还没有火星陨石这个美观，目前科研队仅仅发现了一块水星陨石，所以除去水星不谈，火星陨石就是市场上价值最高的陨石，之所以价值高，是由于曾经科研队在火星上发现了微生物化石，证明火星上曾经是有生命体的，这使得火星陨石极具科研价值，目前陨石爱好者可谓是几经疯狂的热爱陨石，认为陨石有地球不具备的元素，磨粉加热内服，可以治疗癌症，也有很多爱好者用来煮汤，泡茶，可以调节人体磁场，越喝越健康，火星陨石是一件概率性的藏品，掉落在地球上的概率极低，正所谓千金易得一宝难求，时（石）来运转。
英文翻译：A meteorite, also known as a meteorite, is an unburned mixture of stone, iron, or stone and iron scattered rapidly on the surface of the Earth or other planets by meteors or dust fragments from the universe that have left their original orbits outside the Earth.
As the saying goes, 'monks from other places chant scriptures', and stones from other places are also popular. The price of a small meteorite on the market is comparable to that of gold. There is also a group of people in the market who are professional meteorite hunters, also known as Star hunters. In China, their job is to hunt for meteorites in the mountains, forests and gobi desert, and sell them for huge profits. The search for treasure is fraught with perils, but the lure of overnight riches is constant.
Meteorites are pieces of debris from other bodies in the solar system outside Earth. The vast majority come from asteroids between Mars and Jupiter. A few come from the moon and Mars. Meteorites are usually divided into three categories according to the content of iron and nickel in their interior: stone meteorites, iron meteorites and stone meteorites. The Olivine meteorite is one of the rarest and most precious meteorites, with less than 1% found globally.
The collection is introduced

Look at the meteorite crust and gas seal characteristics
The molten shell of meteorites is mostly gray and black, which is the inevitable molten appearance of meteorites burning carbonization through space and the atmosphere. The molten shell generally has about a millimeter, but also some because the combustion is quite thick. Meteorite vapor marks are carved by the atmosphere on meteorites. Meteorite vapor marks are different from the wind erosion and water erosion of ordinary stones, including the soft texture like the cooling holes of magma. Meteorite vapor marks are more represented by the shape of nail pattern or streamlined feature, with relatively hard and masculine texture. In the falling process of the powerful shock wave to create the masculinization of meteorites, simply said that the earth's rock surface traces appear soft, and meteorite gas imprint is mostly rigid, which is the basic texture characteristics. Of course, many meteorites with high altitude and low altitude explosions do not have the characteristics of molten crust gas imprint, the key we have to carefully observe. From the perspective of meteorite falling process, meteorite falling is mainly divided into three categories: orientation, inversion and rotation. In the process of meteorite shooting, we find that most of the air marks of oriented meteorite melt in one direction, with more edges and corners and edge lines. Reversed meteorites will appear a variety of gas prints, in the shape of the atmosphere to create a more comprehensive, looks more diverse edge arc and elliptical shape is more. In the course of rotating meteorites, they mostly show sphericity and spiral torsion. Of course, meteorites travel through space in a variety of ways, so it's important for us to be flexible in our judgments.
Meteorite surface has a very obvious melting shell, and the gas imprint is very obvious, through the university of geosciences research, the meteorite falling on the earth will still remain in the characteristics of the planet, meteorite surface color red for rare meteorite, in the meteorite status of the second, second only to mercury meteorite value.
Judging from the internal appearance of the meteorite from the break in the molten crust.
Meteorites texture because generally contain nickel silicate and elements, the most basic methods from a meteorite landing lesions look have stars light refraction, if from nearly as you can see in the sun shining, the basic can conclude that silicate crystals refracted and shiny nickel elements, from these internal features we can also distinguish the meteorites. Of course, it is impossible to generalize about the diversity of meteorite species and the limitations of our known experience, but we need to constantly enrich the practical experience for reference.
From the meteorite's peculiar temperament and environmental comparison to determine.
Meteorites from the universe space of the world have the earth stone different unique temperament, meteorites has the aura of energy of the universe and the earth stone texture, there is a big difference between the unique visual sense of energy makes meteorites had unusual stone temperament, like we used to see the Chinese suddenly see westerners usually fresh and strange, meteorites from the inside out of special aura let us can be induced to a mysterious sense of energy. This is the way to judge from temperament. In deserts, gobi, mountains and other places, if we find rocks that are different from the surrounding rocks and environments, we should pay attention to them. Combined with our experience, we can basically determine whether they are meteorites.
We can get the Martian silicate differentiation by conventional geochemistry when meteorites are pieces that have been ejected from Mars by impact. After silicate differentiation, the inert gas AR-40 formed by the decay of radionuclide K-40 accumulates in the mineral, indicating the time of silicate differentiation. But during the impact, the inert gas escapes and the clock is reset. By dating the K-AR age of Martian meteorites, we can tell when these meteorites left Mars. The amount of cosmogenic nuclides in meteorites can be used to infer the duration of the meteorite's stay in space. Once the meteorite falls to the Earth, the generation of cosmogenic nuclides stops. We can also judge when the meteorite falls to the earth by the amount of radiogenic cosmogenic nuclides.
Meteorite news is emerging in endlessly, meteorite price has been reported to gram to calculate, it is to fry 50 thousand 110 grams, want to know what kind of meteorite has value, is worth investing, believe meteorite lovers all know a fist size meteorite clinch a deal price more than 80 million, with the same age as the earth. From the picture that more than eight thousand meteorite is not Martian meteorites this beautiful, only the current scientific research team found a mercury meteorites, so remove mercury, Mars meteorite is the market value of the highest meteorites, high value, is due to the scientific research team found on Mars microbial fossils, prove that Mars was once a life, which makes the Martian meteorites have scientific research value, extremely the meteorite lovers is crazy love meteorites, several times that meteorites have the earth does not have elements, flour heating take orally, can cure cancer, also has a lot of fans used to cook soup, tea, can adjust the human body magnetic field, The more you drink, the healthier, Mars meteorite is a probabilistic collection, the probability of falling on the earth is very low, is the so-called qianjin easy to get a treasure is hard to find, when (stone) to operate.
