陨石也称“陨星”，是地球以外脱离原有运行轨道的宇宙流星或尘碎块飞快散落到地球或其它行星表面的未燃尽的石质、铁质或是石铁混合的物质。玻璃陨石坠落地表后，产生的高温融化地表矿物，冷却后的产物，属于二次衍生物，它本质上是地表的二氧化硅并非地外的陨石。玻璃陨石是与某种石陨石伴生的一种。英国生物学家达尔文1844在澳大利亚取得一块钮扣状玻璃质石块，今后在国际规模内这品种似玻璃质石块通称为"玻璃陨石"。它是一种天然玻璃物质。

因为外观似黑曜岩，故又称似黑曜岩。但两者的成分、结构都不一样。大多数玻璃陨石的形状与熔融溅射物的形状类似，有球状、细长状、哑铃状、液滴状、钮扣状和不规则的块状等。它成群地撒落在内地上或海底沉积物中。玻璃陨石的色彩有黑、墨绿、棕褐，表层具拉长状气泡及巨细不等的气泡，有的似如月球外表的环形山状图案。大多数玻璃陨石的形状与熔融溅射物的形状类似，常呈黑色或深绿色，半透明，从前各种形状的玻璃陨石遍及认为是陨星事情形成的，大陨星冲撞使地表及陨星的碎裂物很快融熔、敏捷冷却结晶而成。对于玻璃陨石的成因现已探明，它是某种石陨石高速陨落时消融后的产物。尽管现在大多数科学家认为是无穷的陨石或彗星（核）碰击地球，使地球外表物质熔融，溅射到空中，急速冷却而成。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。

Meteorites are unburned materials made of stone, iron or a mixture of iron and stone that are scattered rapidly to the surface of the earth or other planets by cosmic meteors or dust fragments that have left their original orbits outside the earth. After the glass meteorite falls to the earth's surface, it produces the high temperature to melt the surface mineral, after cooling the product, belongs to the secondary derivative, it is essentially the earth's surface silica is not the extraterrestrial meteorite. The glass meteorite is a kind of stone meteorite associated with it. British biologist Charles Darwin acquired a button-shaped glass stone in Australia in 1844. In the international scale, this kind of glass stone is known as "glass meteorite". It is a natural glass substance.

It is also called obsidian because it looks like obsidian. But the composition and structure of both are different. Most glass meteorites have shapes similar to those of molten sputtering objects, including spherical, elongated, dumbbell-shaped, droplet shaped, button shaped and irregular lumps. It is scattered in swarms in sediments on the inner ground or on the sea floor. The color of glass meteorites are black, dark green, brown, surface with elongated bubbles and size of the bubble, some like the lunar appearance of the craters like patterns. Most of the shape of glass meteorites and molten sputtering similar shape, often black or dark green, translucent, formerly various shapes of glass meteorites throughout is believed to be formed by meteorites, large meteorites impact the surface and meteorite fragments quickly melt, agile cooling crystallization. The origin of the glass meteorite is now known, it is a kind of stone meteorite rapid fall after the product of melting. Although most scientists now believe it was formed when an infinite number of meteorites or comets (nuclei) smashed into the earth, causing the material on the earth's surface to melt and splash into the air, rapidly cooling. There are two hypotheses about the formation of glass meteorites that are closest to the facts. The most likely scenario is that glass meteorites are large meteorites or comet cores that hit the earth, causing molten rock on the earth's surface to spewing out of the crater and rapidly cooling. Or glass meteorites formed from rain of glass falling from space into the earth's atmosphere.
