陨石是指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。全世界已收集到4万多块陨石样品,石陨石主要成分是硅酸盐。它们大致可分股票手机上怎么开户为三大类: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)。

Mete股票在手机上怎么开户o股票在手机上怎么开户rites are fragments of objects in the so股票在手机上怎么开户lar 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 ha股票在手机上怎么开户ve 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).

是坠落最多的一类陨石。主要或全部由硅酸盐矿物,特别是铁镁硅酸盐组成的陨石的总称,其中金属铁-镍含量低于30%。根据岩石结构有无球粒存在而分为球粒陨石和非球粒陨石两大类;根据整体化学成分,球粒陨石被分为碳质球粒陨石、普通球粒陨石和顺火辉石球粒陨石类。非球粒陨石的第三级分类也是根据化学(矿物)组成进行的,岩石(矿物)含钙量高的叫富钙无球粒陨石,含钙低的叫贫钙无球粒陨石。石陨石的成分和外表都很像超基性岩,密度为3~3.5 克/厘米’。它在野外易被误认成普通岩石,所以虽其陨落数量很大,占总坠落数92%以上,但寻获数只占全部寻获陨石数的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.

苍茫宇宙,浩瀚无垠,有太多的未知等待着人类去探索。长久以来,被称作“天外来石”的陨石因极高的科研价值一直受到众多天文学家和地质学家的热捧。如今,陨石收藏热席卷全球,能够收藏陨石成了收藏家身份地位的象征。石铁陨石又称陨铁石。是比较罕见的一类陨石,占陨石数2%~4%。铁镍和硅酸盐矿物含量相当(30%~65%)。主要矿物有橄榄石、各种辉石、铁纹石和镍纹石。其中石铁陨石因其独特的历史价值和科研价值备受收藏新贵们的追逐。

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.

据悉,每年降落到地球上的陨石有20多吨,数量有两万多块,其中99%以上是石陨石和铁陨石,石铁陨石只占几乎0.3%左右的比例,换句话说,每年降落到地球上的石铁陨石只有60块左右,其中有一部分陨落在大海,一部分不能被人类发现珍藏,还有一部分被收藏在大型博物馆中。物以稀为贵,正因为此,石铁陨石的商业价值及科价值极高,即使是大收藏家,能够收藏到石铁陨石的也寥寥无几。

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.

此件藏品是一件石铁陨石,重200克。品相完美,这块石铁陨石,有磁性,表面有些许的晶体非常漂亮而美丽,至今一直在收藏,此陨石其表面呈现铁的光泽,且外表布满疤痕和坑洞,敲之铮铮作响。内部含有大量稀有矿物质,无论从历史价值和科研价值来说都是稀有的,升值潜力无限。

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.
