在阿波罗14号使命返回的几个角砾岩样品中观察到球粒。这些月球陨石球粒被认为是在一次大的撞击事件中形成的，也许是形成英武纪盆地的那一次。这表明，有些陨石球粒也是由撞击过程形成的，如撞击后的结晶、熔化和磨损以及在行星表面撞击产生的底涌和回落沉积物中的扩散。
Chondrules have been observed in several breccia samples returned by the Apollo 14 mission. These lunar chondrules are believed to have formed during a large impact event, perhaps the one that formed the Imbrian Basin. This suggests that some meteoritic chondrules are also formed by impact processes such as crystallization after shock melting and abrasion and diffusion in base-surge and fall-back deposits generated by impacts on planetary surfaces.
