隕石也稱“隕星”，是地球以外脫離原有運行軌道的宇宙流星或塵碎塊飛快散落到地球或其它行星表面的未燃盡的石質、鐵質或是石鐵混合的物質。2019年10月11日凌晨約0時16分前后，一顆隕石可能墜落在東北吉林省松原市附近，遼寧沈陽、吉林長春、吉林松原、黑龍江哈爾濱等黑龍江和吉林多地網友均目擊到這顆隕石墜落時產生的火光。因為隕石是外太空的來物，隕石確定真假是需要儀器鑒定的，肉眼只有輔助的作用。大多數隕石來自于火星和木星間的小行星帶，小部分來自月球和火星。隕石大體可分為石質隕石、鐵質隕石，石鐵混合隕石。隕石的平均密度在3～3.5之間，主要成分是硅酸鹽。隕鐵密度為7.5～8.0，主要由鐵、鎳組成。隕鐵石成分介于兩者之間，密度在5.5～6.0間。隕星的形狀各異，最大的隕石是重1770千克的吉林1號隕石，最大的隕鐵是納米比亞的戈巴隕鐵，重約60噸。中國隕鐵石之冠是新疆青河縣發現的“銀駱駝”，約重28噸。
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. A meteorite may have crashed near Songyuan city in northeast China's Jilin province around 04:16 am on Oct 11, 2019. Netizens in Heilongjiang and Jilin provinces including Shenyang, Liaoning, Changchun, Songyuan and Harbin witnessed the firelight from the meteor. Because meteorites are from outer space, meteorites to determine the true and false is the need for instrument identification, the naked eye only auxiliary role. Most meteorites come from the asteroid belt between Mars and Jupiter, and a few from the moon and Mars. Meteorites can be roughly divided into lithic meteorites, ferroic meteorites, ferroic mixed meteorites. Meteorites have an average density of 3 ~ 3.5 and are mainly composed of silicates. The density of meteorite iron 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 various shapes, the largest meteorite being the Jilin 1 meteorite weighing 1,770 kg, and the largest meteorite being the Goba meteorite in Namibia, weighing about 60 tons. The crown of Meteorite in China is a "silver camel" found in Qinghe County, Xinjiang province, weighing about 28 tons.
隕石在高空飛行時，表面溫度達到幾千度。在這樣的高溫下，隕石表面融化成了液體。后來由于低層比較濃密大氣的阻擋，他的速度越來越慢，融化的表面冷卻下來，形成一層薄殼叫“熔殼”。熔殼很薄，一般在1毫米左右，顏色是黑色或棕色的。在熔殼冷卻的過程中，空氣流動在隕石表面吹過的痕跡也保留下來，叫“氣印”。氣印的樣子很像在面團上按出的手指印。熔殼和氣印是隕石表面的主要特征。若是你看到的石頭或鐵塊的表面有這樣一層熔殼或氣印，那你可以立刻斷定，這是一塊隕石。但是落下來的年代較長的一些隕石，由于長期的風吹、日曬和雨淋，熔殼脫落了，氣印也就不易辨認出來了，但是那也不要緊，還有別的辦法來辨認。
When meteorites fly high, their surface temperatures reach thousands of degrees. At such high temperatures, the surface of the meteorite melted into liquid. Later, as the thicker atmosphere in the lower layer blocked his speed, the melting surface cooled down, forming a thin shell called a "molten shell." The shell is very thin, generally around 1 mm, the color is black or brown. As the shells cool, traces of air flowing across the meteorite's surface remain, known as "gas prints." Air prints look a lot like finger prints on dough. Molten crust and gas seals are the main features of meteorite surfaces. If you see such a crust or vapor imprint on the surface of a rock or piece of iron, you can immediately tell that it is a meteorite. But some of the older meteorites, blown off by the wind, the sun, and the rain, are hard to make out. But that doesn't matter, there are other ways to make out.
鑒定一塊樣品是否為隕石，可以從以下幾方面考慮：1．外表熔殼：隕石在隕落地面以前要穿越稠密的大氣層，隕石在降落過程中與大氣發生磨擦產生高溫，使其表面發生熔融而形成一層薄薄的熔殼。因此，新降落的隕石表面都有一層黑色的熔殼，厚度約為1毫米。2．表面氣印：另外，由于隕石與大氣流之間的相互作用，隕石表面還會留下許多氣印，就象手指按下的手印。3．內部金屬：鐵隕石和石鐵隕石內部是有金屬鐵組成，這些鐵的鎳含量很高（5%～10%）。球粒隕石內部也有金屬顆粒，在新鮮斷裂面上能看到細小的金屬顆粒。4．磁性：正因為大多數隕石含有鐵，所以95%的隕石都能被磁鐵吸住。5．球粒：大部分隕石是球粒隕石（占總數的90%），這些隕石中有大量毫米大小的硅酸鹽球體，稱作球粒。在球粒隕石的新鮮斷裂面上能看到圓形的球粒。
To determine whether a sample is a meteorite, consider the following aspects: 1. Appearance melts shell: meteorite should pass through dense atmosphere before falling to the ground, meteorite produces high temperature in the process of falling and atmosphere friction, make its surface produces melting and form a thin layer of molten shell. As a result, newly landed meteorites have a black shell about 1 mm thick. 2. Surface airprints: In addition, meteorites leave many airprints on the surface, like fingerprints pressed by a finger, due to their interaction with the great airflow. 3. Interior metal: Iron meteorites and ferrocenites are composed of metallic iron, which is high in nickel (5-10%). Chondrites also contain metal particles, which can be seen on the fresh fracture surfaces. 4. Magnetism: Because most meteorites contain iron, 95% of meteorites are held by magnets. 5. Chondrites: Most meteorites are chondrites (90% of the total), which contain large millimeters-sized silicate spheres called chondrites. Circular chondrites can be seen on the fresh fracture surfaces of chondrites.
稀有金屬隕石Rare metal meteorite，主要成份為鐵、鎳、錳、砷、鉬、鋯、鈮、釕、銠、銀、鎘、銦、錫、銻過度金屬的隕石。主要由鐵紋石和鎳紋石兩種礦物組成，其次含有少量的石墨、隕磷鐵鎳礦、隕硫鉻礦、隕碳鐵、鉻鐵礦和隕硫鐵等。在化學成分上除Ni和Fe外，還含有As、Mo、Mn、Zr、Nb、Ru、Rh、Ag、Cd、In、Sn、和Ir等元素。有少數鐵隕石還含有硅酸鹽包體。稀有金屬隕石的分類主要根據Fe、和Zr、Nb、Ru、Rh、Agr的含量及其構造特征，分為13個群。隕石具有很高的科學研究價值。通過對隕石體內放射性物質的分析測定，我們可以推算出隕石的年齡，推測隕石形成后的經歷。隕石出售138060-84568150000-80998隕石是地球以外的宇宙流星脫離原有運行軌道或成碎塊散落到地球上的石體，它是人類直接認識太陽系各星體珍貴稀有的實物標本，極具收藏價值。

It is mainly composed of two minerals, ferric and nickel, followed by a small amount of graphite, meteorite, chromite, carbon, chromite and ferric sulfide. In addition to Ni and Fe, it also contains As, Mo, Mn, Zr, Nb, Ru, Rh, Ag, Cd, In, Sn, and Ir. A few iron meteorites also contain silicate inclusions. According to Fe, Zr, Nb, Ru, Rh, Agr and their structural characteristics, rare metal meteorites are classified into 13 groups. Meteorites are of great scientific value. By analyzing the radioactive material in meteorites, we can calculate the age of meteorites and infer the experience of meteorites after their formation.
