| Abstract: | Enstatite in the Qingzhen meteorite has been studied by high-resolution TEM and ODI. The (010) structural images show the intergrowth of clinoenstatite and orthoenstatite and also the presence of long-period structure. These features suggest that the Qingzhen meteorite suffered quenching and then underwent a weak thermal metamorphism. |
