Knowledge of the shock remanent magnetization (SRM) structure is crucial to interpret the spatial changes in magnetic anomalies observed over the impact crater. This study reports the SRM intensity and stability structures of single-domain titanomagnetite-bearing basalt based on the SRM acquisition experiments, remanence measurements for divided subsamples, and impact simulations. The SRM properties systematically change with increasing pressure, and three distinctive aspects are recognized at different pressure ranges: (1) constant intensity below 0.1 GPa, (2) linear trend as intensity is proportional to pressure up to 1.1 GPa, and (3) constant intensity and increasing stability above 1.9 GPa. The SRM intensity and stability structures suggest that the crustal rocks containing the single-domain titanomagnetite originally had an SRM intensity structure according to the distance from the impact point, which changed depending on the remanence stability after the impact.
