Outline of Final Research Achievements

The objective of this study is to determine the Hugoniot curve of forsterite, one of the most important silicates, in the density-pressure-temperature-entropy space. We conducted a series of laser shock experiments using a high power laser and obtained shock-induced radiance and shock velocity in forsterite samples under 400-900 GPa compression. Our results indicate that the degree of vaporization of forsterite after shock compression is much higher than previously thought. Hypervelocity impacts at >30 km/s on the Hadean Earth may produce a transient O2-rich atmosphere. This hypothesis can be tested by the geochemical analyses of impact-related geologic record.
