Intergrowth textures of diaplectic glass and crystal in shock-loaded P-anorthite

The intergrowth of diaplectic glass and primitive anorthite has been observed in fragments shocked to 300 kbar. The textures observed by electron microscopy are similar to those produced in shocked quartz crystals. The diffuseness of reflections, related to antiphase domains, show no noticeable change in comparison with unshocked specimens. These results indicate that no gradual change in original domain size occurs and that the transformation of primitive anorthite to diaplectic glass occurs abruptly.
