Shock metamorphic textures induced by pre-heated shock recovery experiments using olivine-phyric basalt

Abstract

We performed pre-heated shock recovery experiments to reveal contributions of temperature for shock textures. Initial high-temperature induced lowering shock pressures for maskelynitization. Olivine shocked at 39 GPa/750 ^oC showed a new Raman peak around 670 cm^-1 which has been obtained from olivine around shock melts in highly shocked Martian meteorites. Temperature-controlled shock experiments will provide better constraints on relations between shock pressures and corresponding features.
