精品月球陨石
月球陨石是地球以外未燃尽的宇宙流星脱离原有运行轨道或程碎块飞快散落到地球或其它行星表面的石质的、铁质的或是石铁混合物质,也称"陨星"。大多数陨石来自于火星和木星间的小行星带,小部分来自月球和火星。陨石大体可分为;石质陨石,铁质陨石,石铁混合陨石。每类陨石下面又有它们的子项。
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,灰绿色,黄色,棕黄色,混合色等。成斑状结构的构造和杏仁构造并存在黑云母。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,及尚不清楚的矿物。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终确认。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。
该石头有一个非常平整的切割面。这个面上与整个石头的外部有一层玻璃质的熔壳,并且可以看到犹如拇指印一样的痕迹。同时该石头硬度高,比重大。从该角度看:石头的外部有规则德尔横向纹理,底部有一个小平面,边缘有碰撞发生的残缺。从整体形态可见其鲜明的:定向垂直陨落特征!这是一块矿物质和微量元素丰富的,定向陨落的月球陨石,极具深入研究和收藏的意义和价值,属于经典的月球陨石,那收藏价值肯定还会再提升,市场价格势必也会更占优势一些,具有较高的收藏价值。
Lunar meteorite is a kind of stone, iron or mixed material of stone and iron, also known as "meteorite", which is an unburned cosmic meteor outside the earth, breaks away from its original orbit or path and falls quickly on the surface of the earth or other planets. Most meteorites come from the asteroid belt between Mars and Jupiter, and a small part from the moon and Mars. Meteorites can be roughly pided into; Stone meteorite, iron meteorite, stone iron mixed meteorite. Under each type of meteorite, there are their sub items. Lunar meteorites can be pided into volcanic rocks and sedimentary rocks. Lunar basalt is one of the main rocks constituting the moon. Its colors are black, white, dark purple, purplish red, green, dark green, grayish green, yellow, brownish yellow, mixed color, etc. Porphyritic structure and almond structure, with biotite. Common sulfides in lunar meteorites include meteorite pyrite, pyrite, chalcopyrite, chalcopyrite, pyrite, and unknown minerals. The transparent molten crust on the surface of lunar meteorite, which belongs to volcanic rock, is formed after the transparent material in lunar rock is melted at high temperature. Other melting phenomena, such as molten shell, molten flow pattern, molten flow line, groove, molten corrosion pit, and edges and corners formed by directional falling, are very obvious. The characteristics of transparent molten crust of lunar meteorites are the symbol of judging lunar meteorites. Due to the long time of falling to the earth, the possibility of losing the transparent molten shell of lunar igneous rock meteorites that have been seriously wind eroded will increase greatly. Usually, this phenomenon will not affect the final confirmation of lunar meteorites. Granular and massive agglomerated bicrystal aggregate anorthosite and micro ban molten breccia are common in lunar meteorites. The color is colorless, white, dark gray, meat red, pink, yellow, light yellow, green, showing glassy luster, transparent to translucent. The plate-shaped or flat columnar single crystal is usually white, and acicular olivine can be seen in the plate-shaped single crystal. The characteristics of breccia anorthosite in lunar meteorites are important scientific basis for confirming lunar meteorites. The stone has a very flat cutting surface. There is a layer of glass melting shell on this surface and the outside of the whole stone, and you can see traces like thumb prints. At the same time, the stone has high hardness and large specific gravity. From this point of view: the outside of the stone has regular transverse texture, there is a small plane at the bottom, and the edge is incomplete due to collision. From the overall shape, we can see its distinctive characteristics: directional vertical falling! This is a moon meteorite rich in minerals and trace elements and falling in a directional direction. It is of great significance and value for in-depth research and collection. It belongs to a classic moon meteorite. The collection value will certainly increase again, and the market price is bound to be more dominant, with higher collection value.
