| Research Abstract |
In order to understand metamorphic processes of ice sheet, ice crystal texture analysis and deformation test of artificial ice samples and ice core samples from ice sheet were carried out. In particular, this research was focused on the a-axis orientation distribution of ice crystals. Ice single crystal growth apparatus as a standard sample and thin section sample deformation test apparatus which can be observed crystal orientation and structure during deformation were also designed and developed. As a result, the anisotropic distribution of a-axes orientation was previously found in deep ice core samples may be formed under limited condition was suggested.
