Paleomagnetic Records at Impact Craters
Impact cratering events produce heat, shock, and if water is present, post-impact hydrothermal activity. All of these processes are capable of setting or resetting magnetization in rocks. Therefore, paleomagnetism may be used as a powerful tool with which to understand the physical and chemical conditions associated with crater formation and subsequent recovery. Our group is currently studying impact-related magnetization at the Chicxulub and Chesapeake Bay impact craters. We are also interested in conducting shock experiments on rock samples to understand the effects of pressure and shock-related heating on magnetic remanence and on paleointensities retrieved from shocked materials.
