Shock compression experiments on Kinosaki basalt (2. 7 g/cm<SUP>3</SUP>) was carried out in the interest of collisional phenomena of planetesimals in the early solar nebula. Shock wave attenuation in basalt were examined using in-material manganin and carbon pressure gauge. The shock waves of 7 and 33 GPa in peak pressure attenuated with the attenuation rate of -1. 8 and -1. 6, respectively. Three attenuation effects were considered: rarefaction wave effect, geometrical expansion effect, and energy dissipation effect. In the rarefaction effect, two waves, reflected wave and edge wave, were newly considered. Our result showed that the reflected rarefaction wave and the geometrical expansion effects affected on shock pressure attenuation and that the energy dissipation effect could be regarded negligible small. The attenuation rate was consistent with that of the impact fragment ejection velocity.
