Compositional Effects of Low-Pressure Impacts in Chondritic Meteorites: Oxygen Isotope Homogenization and Mg-Fe Diffusion in Matrix Olivine and Presolar Grains
Recent work has explored the effects of low-intensity impacts into porous chondrite precursors. We show oxygen-isotope homogenization of presolar grains and Mg-Fe diffusion in fine-grained matrix are potential consequences of this process.
