| Research Abstract |
In order to investigate a meteorite impact phenomenon, the shock metamorphism technique in a large laser facility was developed. The shocked sample (olivine) was fully recovered by using the recovery cell which consists of aluminum with a titanium plate in the front of theolivine. From the analysis of the recovered olivine, the melting, plastic deformation, and elastic deformation of the shocked sample modeled as a shock compression mechanism in the meteorite impact crater interior could be observed, and the shock metamorphism mechanism in the crater interior was able to be verified. Moreover, it succeeded in the observation of the sound velocity for evaluating the shock decay ratio to the interior.
