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。

Meteorites, also known as "meteorites", are the unburned stone, iron or mixed materials of stone and iron that are scattered rapidly on the surface of the earth or other planets by cosmic meteors or dust fragments outside the original orbit of the earth.

因为陨石是外太空的来物，陨石确定真假是需要仪器鉴定的，肉眼只有辅助的作用。大多数陨石来自于火星和木星间的小行星带，小部分来自月球和火星。陨石大体可分为石质陨石、铁质陨石，石铁混合陨石。

Because meteorites are from outer space, meteorites to determine true or false is the need for instrument identification, the naked eye only auxiliary role. Most come from the asteroid belt between Mars and Jupiter, and a few from the moon and Mars. Meteorites can be roughly divided into stone meteorites, iron meteorites, iron mixed meteorites

陨石的平均密度在3～3.5之间，主要成分是硅酸盐。陨铁密度为 7.5～8.0，主要由铁、镍组成。陨铁石成分介于两者之间，密度在5.5～6.0间。陨星的形状各异，最大的陨石是重1770千克的吉林1号陨石，最大的陨铁是纳米比亚的戈巴陨铁，重约60吨。中国陨铁石之冠是新疆青河县发现的“银骆驼”，约重28吨。 ^[1] 

The average density of meteorites is between 3 and 3.5. The iron density of meteorite is 7.5 ~ 8.0, mainly composed of iron and nickel. The composition of meteorite is between the two and the density is between 5.5 and 6.0. Meteorites come in all shapes and sizes. The largest meteorite is the jilin 1 meteorite, which weighs 1770 kilograms. The largest meteorite is the goba meteorite in namibia, which weighs about 60 tons. The China meteorite iron crown is the "silver camel" found in qinghe county, xinjiang, weighing about 28 tons.

全世界已收集到4万多块陨石样品，有各种样式的。它们大致可分为三大类：石陨石（主要成分是硅酸盐)，铁陨石（铁镍合金）和石铁陨石（铁和硅酸盐混合物）。

陨石指坠落于地面的陨星残体，由铁、镍、硅酸盐等矿物质组成，亦称陨星石。也指含石质较多或全部为石质的陨星。在含碳量高的陨石中还发现了大量的氨、核酸、脂肪酸、色素和11种氨基酸等有机物，因此，人们认为地球生命的起源与陨石有相当大的关系。

       我们推荐的这类陨石经有个部门检测为乌金陨石。其中成分更有特点与稀有。

More than 40,000 meteorite samples, of various types, have been collected worldwide. They can be divided into three broad categories: stone meteorites (mostly composed of silicates), iron meteorites (iron-nickel alloys), and stone meteorites (mixtures of iron and silicates).

Meteorites refer to the remnants of meteorites falling to the ground, which are composed of iron, nickel, silicate and other minerals, also known as meteorite. Also a meteorite that contains or is composed entirely of stone. In the high carbon meteorite also found a large number of ammonia, nucleic acid, fatty acids, pigments and 11 kinds of amino acids and other organic matter, therefore, people think that the origin of life on earth and meteorites have a considerable relationship.

This kind of meteorite that we recommend classics has a branch to detect for black gold meteorite. The ingredients are more characteristic and rare.

· 熔坑：陨石表面都布有大小不一、深浅不等的凹坑，即熔蚀坑。不少陨石还具有浅而长条形气印，可能是低熔点矿物脱落留下的。

· 熔壳：陨石在经过大气层时，极高的温度导致陨石表面熔融，产生了一层微米至毫米级别玻璃质层，这就是熔壳。当陨石在地表存在较长时间后，其熔壳易被风化而消失掉。

· 比重：陨石因为含铁镍比重较大，铁陨石比重可达8，石陨石也因常含20铁镍，比一般岩石比重也大些。但是，存在极少量的石质陨石（如碳质球粒陨石等）因不含或金属含量极低，其密度与一般地球岩石相似。

· 磁性：各种陨石因含有铁而具强度不等的磁性。经风化的陨石没有磁性，因而也就不算陨石了。

· 条痕：陨石在无釉瓷板上摩擦一般没有条痕或仅有浅灰色条痕，而铁矿石的条痕则是黑色或棕红色，以此加以区别。

· crater: the meteorite surface is covered with pits of different sizes and depths, namely, corrosion pits. Many meteorites also have shallow, elongated gas marks that may have been left by minerals with low melting points.

· molten shell: when meteorites pass through the atmosphere, the extremely high temperature causes the meteorite surface to melt, resulting in a layer of micron to millimeter glass layer, which is called molten shell. When meteorites exist on the surface for a long time, their molten shells are easy to be weathered away.

· specific gravity: meteorites because the proportion of iron and nickel is large, the proportion of iron meteorites can reach 8, stone meteorites because often contain 20 iron and nickel, than the general proportion of the rock is also larger. However, there are a very small number of stony meteorites (such as carbonaceous chondrites, etc.) that are very low in content or metal and similar in density to ordinary earth rocks.

· magnetism: all kinds of meteorites have magnetism with different strength due to iron. Meteorites do not have magnetic weathering, so it is not a meteorite.

Striation: meteorite friction on unglazed ceramic plates generally has no striations or only light gray striations, while iron ore striations are black or reddish-brown to distinguish.
