- Abstract
TEM images of initial and shocked opal showing products of tridymite, coesite, and cristobalite together with opal-CT. 2018.pdf 11th Planetary Crater Consortium 2020 (LPI Contrib. We report the first impact experiments on opal-A The phase transformation and deformation features of shocked opal-A were investigated by X-ray diffraction (XRD) and transmission electron microscopy (TEM) analyses. The main advantage of LIPIT technique is that the size of projectile and the impact speed can be controlled in desired ways and provides dynamic experiments at length scales that enable holistic analysis of impact phenomena using electron microscopy and synchrotron X-ray diffraction techniques.
