玻璃陨石与月球陨石,究竟神秘在何处?

玻璃陨石与月球陨石,究竟神秘在何处?
击变玻璃(玻璃陨石)成因──彗星撞击
【分类号】:P185.83
地球上的陨石除玻璃陨石外,分布几乎是均匀的,在有人们居住的地区是容易被发现,而在荒无人烟的地区,有记录的十分罕见,北极、南极地区,现在去考查的人们极易拾得陨石,也是情理之中的事情。
In addition to glass meteorites, the distribution of meteorites on the earth is almost uniform. It is easy to find meteorites in areas inhabited by people, while in areas inhabited by no one, records are very rare. It is also reasonable that people in the Arctic and Antarctic regions can easily pick up meteorites now.
玻璃陨石在地球上的分布,与其它陨石完全不同,玻璃陨石在地球上有一定的陨落区,每个陨落区中的玻璃陨石,代表了一次天体陨落事件,陨落区中玻璃陨石是同一陨落事件的产物。
The distribution of glass meteorites on the earth is completely different from that of other meteorites. Glass meteorites have certain meteorite areas on the earth. Glass meteorites in each meteorite area represent a celestial meteorite event. Glass meteorites in the meteorite area are the product of the same meteorite event.

玻璃陨石形成民间有两种假说最为接近事实,月球起源说中火山喷发说、冲击变质说。根据美国科研局最新消息,可能性最大的是玻璃陨石是巨大的陨石或彗核撞击地球,使地球表层岩石熔融高速溅出坑外急速冷却而成。或者是玻璃陨石是从宇宙空间降落到地球大气层的玻璃雨形成的。
There are two kinds of folk hypothesis about the formation of glass meteorites, the volcanic eruption hypothesis and the impact metamorphism hypothesis in the lunar origin hypothesis. According to the latest news from the U.S. Bureau of Scientific Research, the most likely thing is that glass meteorites are formed when giant meteorites or comet nuclei hit the Earth, causing the surface rocks of the Earth to melt and splash out at high speed and rapidly cool out of the crater. Or glass meteorites are formed by glass rain falling from space to the earth's atmosphere。

Glass meteorites, known as "extraterrestrial rocks", are rare and precious. Naturally, some people like to collect them. In recent years, a upsurge of glass meteorite collection has gradually arisen in China. In the past three or four years, not only the price of glass meteorite has soared, but also the domestic glass meteorite collection market has gradually taken shape. Four or five years ago, the economic value of glass meteorites was not well known.
因为玻璃陨石在降落过程中为液质体,在高速下它们会被分解为较小的质量体,因此客观上不存在极大质量的玻璃陨石,但它与母石伴生陨落时或许较大的质量体。
Because glass meteorites are liquid bodies in the process of landing, they will be decomposed into smaller mass bodies at high speeds, so there is no objective glass meteorite of great mass, but it may have larger mass bodies when it falls with parent rocks.

月球陨石可分为火山岩和沉积岩两大类,月球玄武岩是构成月球的主要岩石之一,颜色为黑色,白色,暗紫色,紫红色,绿色,墨绿色(俗称黑宝绿),灰绿色,黄色,棕黄色,混合色等。成斑状结构和杏仁构造的构造并存在黑云母。月球陨石中常见的硫化物有陨硫铁、黄铁矿、黄铜矿、方黄铜矿,硫镍铁矿和尚不清楚的矿物。
Lunar meteorites can be divided into volcanic rocks and sedimentary rocks. Lunar basalt is one of the main rocks that make up the moon. Its colors are black, white, dark purple, purplish red, green, dark green ( commonly known as black treasure green ), gray green, yellow, brown yellow, mixed color, etc. Patchy structure and almond structure with biotite. The common sulfides in lunar meteorites are meteorite pyrite, pyrite, chalcopyrite, chalcopyrite, chalcopyrite and unclear minerals.

属火山岩的月球陨石表面呈现的透明状熔壳,是月岩中的透明物质经高温熔融后形成的。其它熔融现象如:熔壳,熔流纹,熔流线,槽沟,熔蚀坑,和定向坠落形成的棱角都十分明显。
月球陨石的透明状熔壳特征,是判断月球陨石标志。因坠落地球时间太久,遭严重风蚀的月球火成岩陨石,失去透明状熔壳的可能性会大增,通常这种现象不会影响对月球陨石的最终确认。
The transparent melting shell on the surface of the lunar meteorite, which belongs to volcanic rocks, is formed by melting transparent materials in the lunar rock at high temperature. Other melting phenomena such as melting shells, melt flow patterns, melt flow lines, grooves, corrosion pits, and edges and corners formed by directional falling are very obvious.
The transparent melting shell feature of the moon meteorite is a symbol for judging the moon meteorite. Due to the long time of falling to the earth, the possibility of losing the transparent melting shell of the lunar igneous rock meteorite severely eroded by wind will greatly increase, usually this phenomenon will not affect the final confirmation of the lunar meteorite

月球陨石中常见成粒状,块状的聚片双晶集合体斜长岩及微班熔融角砾岩。颜色为无色、白色、暗灰色、肉红色、粉红色、黄色、浅黄色,绿色。显玻璃光泽透明至半透明。板状或扁柱状的单晶常为白色,板状单晶内可见针状橄榄石存在。月球陨石中具有角砾斜长岩的特征,是确认月球陨石的重要科学依据。火星陨落的陨石人们把他叫‘火星陨石’,火星陨石也是一种非常少见的陨石物种,比较知名的有‘84001’含有机物的火星陨石,和一种叫‘准晶体’的橄榄石陨石,和含氧铁硅水分子杂化的橄榄石斑晶‘伊丁石火星陨石’。
In lunar meteorites, granular and massive aggregates of poly - schist and bi-crystalline plagioclase and micro-class molten breccia are common. Colors are colorless, white, dark gray, flesh red, pink, yellow, light yellow and green. Show glass luster transparent to translucent. The plate-like or flat columnar single crystal is usually white, and acicular olivine can be seen in the plate-like single crystal. The moon meteorite is characterized by breccia plagioclase, which is an important scientific basis for confirming the moon meteorite. Martian meteorites that have fallen from Mars are called' Martian meteorites', and Mars meteorites are also a very rare meteorite species. The more famous ones are' 84001' Mars meteorites containing organic matter, an olivine meteorite called' quasicrystal', and olivine porphyry crystal' iddingsite Mars meteorite' hybridized with oxygen-containing iron-silicon water molecules.——文章来自网络,尊重原创,如有侵权,通知删除!
