隕石是指來(lái)自地球以外太陽(yáng)系其他天體的碎片，絕大多數(shù)來(lái)自位于火星和木星之間的小行星，少數(shù)來(lái)自月球和火星。全世界已收集到4萬(wàn)多塊隕石樣品，石隕石主要成分是硅酸鹽。它們大致可分為三大類：石隕石（主要成分是硅酸鹽)、鐵隕石（鐵鎳合金）、和石鐵隕石（鐵和硅酸鹽混合物）。
Meteorites are fragments of objects in the solar system other than earth, most of which come from asteroids between Mars and Jupiter, and a few from the moon and Mars. More than 40,000 meteorite samples have been collected all over the world. They can be roughly divided into three groups: stone meteorites (mainly composed of silicates), iron meteorites (iron-nickel alloys), and stone iron meteorites (a mixture of iron and silicate).
是墜落最多的一類隕石。主要或全部由硅酸鹽礦物,特別是鐵鎂硅酸鹽組成的隕石的總稱,其中金屬鐵-鎳含量低于30%。根據(jù)巖石結(jié)構(gòu)有無(wú)球粒存在而分為球粒隕石和非球粒隕石兩大類;根據(jù)整體化學(xué)成分,球粒隕石被分為碳質(zhì)球粒隕石、普通球粒隕石和順火輝石球粒隕石類。非球粒隕石的第三級(jí)分類也是根據(jù)化學(xué)(礦物)組成進(jìn)行的,巖石(礦物)含鈣量高的叫富鈣無(wú)球粒隕石,含鈣低的叫貧鈣無(wú)球粒隕石。石隕石的成分和外表都很像超基性巖,密度為3~3.5 克/厘米’。它在野外易被誤認(rèn)成普通巖石,所以雖其隕落數(shù)量很大,占總墜落數(shù)92%以上,但尋獲數(shù)只占全部尋獲隕石數(shù)的56.3%。
It's the type of meteorites that fall the most. The general term for meteorites composed mainly or entirely of silicate minerals, especially magnesium iron silicate, in which the metal iron-nickel content is less than 30%. According to the existence of chondrules or not, the rock structure can be divided into two categories: chondrites and achondrites. According to the overall chemical composition, chondrites can be divided into carbonaceous chondrites, common chondrites and choriosite chondrites. The tertiary classification of achondrites is also based on chemical (mineral) composition. Rocks with high calcium content are called calcium-rich achondrites, while rocks with low calcium content are called calcium-poor achondrites. Stone meteorites are similar in composition and appearance to ultrabasic rocks with a density of 3~3.5 g/cm '. It is easily mistaken for a normal rock in the wild, so although it has a large number of falls, accounting for more than 92 percent of the total, the number of meteorites found accounts for only 56.3 percent of the total.
蒼茫宇宙，浩瀚無(wú)垠，有太多的未知等待著人類去探索。長(zhǎng)久以來(lái)，被稱作“天外來(lái)石”的隕石因極高的科研價(jià)值一直受到眾多天文學(xué)家和地質(zhì)學(xué)家的熱捧。如今，隕石收藏?zé)嵯砣颍軌蚴詹仉E石成了收藏家身份地位的象征。石鐵隕石又稱隕鐵石。是比較罕見(jiàn)的一類隕石，占隕石數(shù)2%~4%。鐵鎳和硅酸鹽礦物含量相當(dāng)(30%~65%)。主要礦物有橄欖石、各種輝石、鐵紋石和鎳紋石。其中石鐵隕石因其獨(dú)特的歷史價(jià)值和科研價(jià)值備受收藏新貴們的追逐。
The vast universe, the vastness, there are too many unknown waiting for mankind to explore. Meteorites known as "exotic rocks" have long been loved by astronomers and geologists for their high scientific value. Today, meteorite collections are sweeping the world, and the ability to collect meteorites has become a status symbol for collectors. Stone iron meteorite also known as meteorite. Meteorites are relatively rare, accounting for 2% to 4% of meteorites. The content of iron, nickel and silicate minerals is equal (30%~65%). The main minerals are olivine, pyroxene, iron and nickel. Among them stone iron meteorite because of its unique historical value and scientific research value by the collection of the new rich chase.
據(jù)悉，每年降落到地球上的隕石有20多噸，數(shù)量有兩萬(wàn)多塊，其中99%以上是石隕石和鐵隕石，石鐵隕石只占幾乎0.3%左右的比例，換句話說(shuō)，每年降落到地球上的石鐵隕石只有60塊左右，其中有一部分隕落在大海，一部分不能被人類發(fā)現(xiàn)珍藏，還有一部分被收藏在大型博物館中。物以稀為貴，正因?yàn)榇耍F隕石的商業(yè)價(jià)值及科價(jià)值極高，即使是大收藏家，能夠收藏到石鐵隕石的也寥寥無(wú)幾。
down to earth every year more than 20 tons, meteorites number has more than twenty thousand, more than 99% of them are aerolite and iron meteorites, pallasite only accounts for almost 0.3% of proportion, in other words, a year down to the earth's pallasite only about $60, among them are part of the fall in the sea, and part cannot be discovered, and part of the collection in a large museum. Because of this, the commercial value and scientific value of stone iron meteorite is very high, even large collectors, can collect stone iron meteorite is also very few.
此件藏品是一件石鐵隕石，重200克。品相完美，這塊石鐵隕石，有磁性，表面有些許的晶體非常漂亮而美麗，至今一直在收藏，此隕石其表面呈現(xiàn)鐵的光澤，且外表布滿疤痕和坑洞，敲之錚錚作響。內(nèi)部含有大量稀有礦物質(zhì)，無(wú)論從歷史價(jià)值和科研價(jià)值來(lái)說(shuō)都是稀有的，升值潛力無(wú)限。
This collection is a stone iron meteorite, weighing 200 grams. The product is perfect. This iron meteorite is magnetic. Some crystals on its surface are very beautiful and beautiful. It has been collected up to now. The surface of this meteorite shows iron luster, and its appearance is full of scars and potholes. It clanks. There are a lot of rare minerals in the interior, which are rare both in terms of historical value and scientific research value, with unlimited appreciation potential.
