The glass with a higher length-to-diameter ratio was formed under lower temperatures and speed when a meteorite impacted the lunar surface, reflecting milder impact events compared with the formation of glass beads which have a lower length-to-diameter ratio.

陨石撞击月球表面时，在较低的温度和速度下形成了长径比较高的天然玻璃纤维，与具有较低长径比的玻璃珠的形成相比，这反映了月球表面较为温和的微撞击事件。
