Constraining the pressure threshold of impact induced calcite twinning : Implications for the deformation history of aqueously altered carbonaceous chondrite parent bodies
Calcite twinning in carbonaceous chondrite meteorites can be used to reconstruct the deformation history and the parent body environment during and/or after aqueous alteration, but the shock pressure threshold at which the twins develop is unknown. Accordingly, the aim of this study is to determine the magnitude of shock pressure that is needed to generate calcite twins. This was done by measuring
