Magnetic field morphology correlated with surface slopes at the Gerasimovich lunar magnetic anomaly

The crustal magnetic anomalies near the lunar crater Gerasimovich are among the highest-magnitude anomalies on the Moon. Previous work has suggested they formed from the deposition and magnetization of ejecta from the Crisium basin, which is antipodal to the region. In this talk, I will describe the correlation between topographic slope and magnetic field morphology in this region, present a predictive model of magnetic field strength based on slope that reproduces key features of the observed field, estimate the source body magnetization of the fill deposit thickness inside of Gerasimovich crater, and describe the implications of the varying magnetization directions within the group of Gerasimovich anomalies.
