| 描述 玻璃隕石是地外物體劇烈撞擊地球時，地表靶物質熔融後快速凝結的天然玻璃。地表發現的玻璃隕石多呈塊狀，棕黑色到淺綠色，一般為厘米級大小，表面多具空氣動力學熔蝕刻痕。長期的研究證明，玻璃隕石在化學和結構特徵上與地球火山玻璃具有明顯的區別，不是地質作用的產物。 | Description Glass meteorites are natural glass that quickly condenses after the target material on the surface melts when an extraterrestrial object violently hits the earth. Most of the glass meteorites found on the surface are massive, brown-black to light green, generally in the size of a centimeter, with many aerodynamic melt etching marks on the surface. Long-term studies have proved that glass meteorites are clearly different from earth’s volcanic glass in chemical and structural characteristics, and are not the product of geological processes. |
| 挑戰 它在哪裏的隕石撞擊形成？ 可能由德國南部的隕石撞擊形成 | Challenges Where did the meteorite impact form? Probably in Southern Germany |
