Random X-ray diffraction patterns for L6 ordinary chondrites were obtained from in-plane rotation of polished sections. The strains were then obtained using the Williamson-Hall plots for olivine and orthoenstatite. That of olivine nearly shows linear relation for shock stage S1-S6, and that of orthoenstatite shows that linear relation starts to break more than S4, suggesting the transition to clinoenstatite.
