Web5 Apr 2024 · The shock-twinned zircon in NWA 7034 is thus best interpreted as a remnant of shocked bedrock that originated within the central uplift (or peak ring) of a complex crater on Mars and is the most ... WebZircon that has been shocked by the extreme pressures and temperatures unique to impact events deforms in a number of ways. One way is to recrystallise. A pre-impact zircon grain, which might initially be approximately 100 micrometres (0.1 millimetre) in size, can recrystallise into a cluster of hundreds or thousands of subgrains.
