Deformation and transformation textures (i. e. fracture, twinning, mosaicism, recrystallization, phase transformation, melting and evaporation) in naturally and artificially shocked mineral crystals have been reported. The main part of this report is devoted to a description of the shock-induced textures in olivine and some mineral crystals from some achondritic meteorites (i. e. two pallasites, one ureilite and two shergottites) by optical microscopic observation. Deformation textures in artificially shocked olivine crystals were also described. Planar fractures in the olivine crystals were discussed in conjunction with loss of strength at dynamic elastic limits.
