Co-evolution of chondritic organics and minerals during impact metamorphism

Abstract : Chondritic organic matter might have evolved on its parent body where subjected to shock metamorphism [1,2]. If the effects of shock waves on minerals have been studied in details from the experimental and observational approaches [3,4] little is known on their effect on the carbonaceous component. Here, we experimentally exposed fragments of matrix of the Murchison chondrite to shock loading up to 40 GPa. We describe the effects on the mineralogy as well as on the organic component.
