石陨石

陨石(uranolite) 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(40块)和火星(40块)。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。

Meteorite refers to the debris from other celestial bodies outside the earth's solar system. Most of them come from asteroids between Mars and Jupiter, and a few from the moon (40 pieces) and Mars (40 pieces). More than 40000 meteorite samples have been collected all over the world. The main component of meteorite is silicate.

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)。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%。

They can be roughly divided into three categories: Meteorites (mainly composed of silicate), iron meteorites (iron nickel alloy), and stone iron meteorites (mixture of iron and silicate). It's one of the most falling meteorites. A general term for meteorites mainly or wholly composed of silicate minerals, especially FE Mg silicate, in which Fe Ni content is less than 30%. According to the existence of chondrites in rock structure, they are divided into chondrite and non chondrite; according to the overall chemical composition, chondrite is divided into carbonaceous chondrite, ordinary chondrite and CIS pyroxene chondrite. The third classification of non chondrites is also based on the chemical (mineral) composition. Rocks (minerals) with high calcium content are called calcium rich achondrites, and those with low calcium content are called calcium poor achondrites. The composition and appearance of meteorites are very similar to ultrabasic rocks, with a density of 3-3.5 g / cm '. It is easy to be mistaken as ordinary rock in the field, so although the number of meteorites dropped is very large, accounting for more than 92% of the total number of falls, the number found only accounts for 56.3% of the total number of meteorites found.

石陨石是最常见的一种陨石,它含有的75%-90%硅酸盐矿物质(例如橄榄石),10%-25%的镍铁合金,以及硫铁化物。石陨石又分为两个子类:球粒陨石与非球粒陨石。大部分陨石都是球粒陨石,约占所有观测陨石的86%。

Meteorite is the most common type of meteorite. It contains 75% - 90% silicate minerals (such as olivine), 10% - 25% ferronickel alloy, and pyrite. The meteorites can be divided into two subgroups: chondrite and non chondrite. Most meteorites are chondrites, accounting for about 86% of all observed meteorites.

石陨石由硅酸盐矿物如橄榄石、辉石和少量斜长石组成,也含有少量金属铁微粒,有时可达20以上。密度3至3.5。石陨石占陨石总量的95。1976年3月8日15时,吉林地区东西12公里,南北8公里,总面积500多平方公里的范围内,降一场世界罕见的陨石雨。所收集到的陨石有200多块,最大的1号陨石重1770公斤,1976年3月8日陨落。名列世界单块陨石重量之最。吉林陨石表面,有黑色、黑棕色熔壳和大小不等气印。化学组成成分为Sio2占37.2,Mgo2占3.19 Fe占28.43。主要矿物有贵橄榄石、古铜辉石、铁纹石和陨硫铁;次要矿物有单斜辉石、斜长石等。

Meteorites are composed of silicate minerals such as olivine, pyroxene and a small amount of plagioclase. They also contain a small amount of metallic iron particles, sometimes up to more than 20. Density 3 to 3.5. Meteorites account for 95% of the total meteorites. At 15:00 on March 8, 1976, there was a rare meteorite rain in Jilin area, covering a total area of more than 500 square kilometers, 12 kilometers from east to west and 8 kilometers from north to south. More than 200 meteorites were collected. The largest meteorite, No. 1, weighed 1770 kg and fell on March 8, 1976. It is the largest single meteorite in the world. On the surface of the Jilin meteorite, there are black, black brown melting shells and air marks of different sizes. The chemical composition is SiO2 37.2, MgO 2 3.19 and Fe 28.43. The main minerals are chrysolite, augite, ferrites and chondrite; the minor minerals are clinopyroxene and plagioclase.

Meteorites are the most falling meteorites. A general term for meteorites mainly or wholly composed of silicate minerals, especially iron magnesium silicate, in which the content of iron and nickel is less than 30%. According to the existence of chondrites in rock structure, they can be divided into chondrite and non chondrite; according to the overall chemical composition, chondrite can be divided into three types: carbonaceous chondrite, ordinary chondrite and enstatite chondrite. The third classification of non chondrites is also based on the chemical (mineral) composition. Rocks (minerals) with high calcium content are called calcium rich achondrites, and those with low calcium content are called calcium poor achondrites. The composition and appearance of meteorites are similar to ultrabasic rocks, with a density of 3-3.5 g / cm ^ 3. It is easy to be mistaken for ordinary earth rocks in the field. Therefore, although the number of meteorites dropped is very large, accounting for more than 92% of the total number of falls, the number found only accounts for 56.3% of the total number of meteorites found.

此石陨石是刘先生收藏的珍品,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。
