隕石的由來：目前發現地有中國，美國，澳洲，南極大陸等地區。隕石的“家”是遙遠而古老的太空。它們是由地球以外的太陽系其他天體，如小行星、行星、大的衛星或彗星等分裂後產生的碎塊形成的，包含著大量太陽系天體形成和演化的信息。從現在採集到的隕石來看，大部分隕石來源於小行星帶。通過碰撞和引力作用，有些固體顆粒會進入地球軌道，當它們與大氣發生劇烈摩擦後，就開始燃燒，如果這個固體顆粒個頭足夠大，沒有燒盡的部分落到地球上就會成為隕石。
Origin of meteorites: at present, they are found in China, the United States, Australia, Antarctica and other regions. The "home" of meteorites is a distant and ancient space. They are formed by the fragmentation of other celestial bodies in the solar system, such as asteroids, planets, large satellites or comets, which contain a lot of information about the formation and evolution of celestial bodies in the solar system. From the meteorites collected now, most of them come from asteroid belt. Through collision and gravitation, some solid particles will enter the earth's orbit. When they rub violently with the atmosphere, they will start to burn. If the solid particles are big enough, the part that is not burned will fall on the earth and become meteorites.
據有關資料顯示，每年隕落到地球的隕石多達20000塊，僅有20塊被人類撿拾，足見其稀有和珍貴。最近十年，隨著隕石知識的日益普及，想收藏的不斷增多，奇貨可居，國內叫價有時甚至遠高於國際價格。世界上眾多的博物館和研究機構也對隕石充滿了極大的興趣，一直致力於對其所處星體和時代的研究，進一步促進了隕石經濟價值的提升。
According to relevant data, as many as 20000 meteorites fall to the earth every year, only 20 of which are picked up by human beings, which shows that they are rare and precious. In recent ten years, with the increasing popularity of meteorite knowledge, the number of meteorite collections is increasing. The domestic price is sometimes much higher than the international price. Many museums and research institutions in the world are also full of great interest in meteorites. They have been committed to the research of their stars and times, further promoting the economic value of meteorites.
隕石一般密度較大。按照成分的不同可分為三種：鐵隕石、石隕石和石鐵隕石。地球上的石頭有很多種類。隕石中的鐵中要以單質的形式存在，而地球上的石頭中是沒有單質鐵的。隕石一般是對人沒害的。但是裡面可能會存在對人有害的放射性元素。
The density of meteorites is generally large. According to the different composition, it can be divided into three kinds: iron meteorite, stone meteorite and stone iron meteorite. There are many kinds of stones on the earth. The iron in meteorites should exist in the form of a single substance, while there is no single substance in rocks on earth. Meteorites are generally harmless to people. But there may be harmful radioactive elements in it.
石鐵隕石是隕石的一種。這類隕石中硅酸鹽與鎳鐵合金的含量各佔50%。石鐵隕石又分為兩個子類：橄欖隕石與中鐵隕石。
Iron meteorite is a kind of meteorite. The contents of silicate and ferronickel in these meteorites account for 50% respectively. There are two kinds of iron meteorites: Olivine meteorite and iron meteorite.
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。
Outer melting shell: before falling to the ground, the meteorite must pass through the dense atmosphere. In the process of falling, the meteorite will rub with the atmosphere to produce high temperature, making its surface melt to form a thin melting shell. As a result, the newly fallen meteorites are all covered with a layer of black molten shell, which is about 1 mm thick.
表面氣印：另外，由於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。 ．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。 ．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。
Surface gas seal: in addition, due to the interaction between the meteorite and the large air flow, there will be many gas marks on the surface of the meteorite, just like the fingerprint pressed by fingers Internal metal: iron meteorites and iron meteorites are composed of metal iron with high nickel content (5-10%). There are also metal particles in the chondrite, and small metal particles can be seen on the fresh fracture surface . magnetism: because most meteorites contain iron, 95% of them can be attracted by magnets.
專家推薦：隕石是經過遙遠的外太空經過漫長的飄行，又經過急速的墜落、高溫的摩擦降臨了地球，被稱作 “天外來石”的隕石因極高的科研價值一直受到眾多天文學家和地質學家的熱捧。現在，隕石珍藏熱席捲全球，能夠珍藏隕石成了就珍藏家身份職位的象徵，其中隕石有著豐富的歷史價值和科研價值，備受收藏家們的追逐，此石鐵隕石，色澤褐黑，隕石表面布有大小不一、深淺不等的凹坑，即熔蝕坑。內部含鐵較高的石隕石，重量比石隕石大的多，手感很明顯，表面呈金屬光澤，很是珍貴。此件石鐵隕石表面呈現自然燃燒痕跡灼燒痕跡明顯，氣印密集漂亮。實屬罕見，不僅是從此隕石外觀，還是本身的價值來看,都是很高的科研價值、觀賞價值和考古價值，收藏價值和經濟價值，且隨著隕石市場逐步走好，升值空間非常之大
Experts recommend that: Meteorites come to the earth after a long journey through remote outer space, a rapid fall and high temperature friction. Meteorites called "extraterrestrial rocks" have been popular with many astronomers and geologists for their high scientific research value. Now, the meteorite collection heat has swept the world, and the meteorite that can be collected has become a symbol of the status of a collector. Among them, the meteorite has rich historical value and scientific research value, and is chased by collectors. The iron meteorite is brown and black in color, and the surface of the meteorite is covered with craters of different sizes and depths, namely, erosion craters. The meteorite with high iron content in the interior is much heavier than the meteorite, with obvious hand feeling and metal luster on the surface, which is very precious. The surface of this piece of meteorite shows natural burning trace, obvious burning trace, dense and beautiful air mark. It's really rare. Not only in terms of the appearance of the meteorite, but also in terms of its own value, it's of high scientific research value, ornamental value, archaeological value, collection value and economic value. With the meteorite market gradually improving, there's a huge room for appreciation
