Lunar Magnetic Pole Positions Deduced from High Albedo Magnetic Anomalies

M.C. Berguig, M. Hamoudi, Y. Cohen and E. Thebault
The purpose of this research is to investigate the internal origin hypothesis by assuming that the crustal lunar magnetic field was generated by a paleo-dynamo process. The study is focused on four comparatively high intensity magnetic anomalies associated with high marked swirl albedo. These four formations: Reiner Gamma, Descartes Formation, Mare Marginis and Mare Ingenii, all having a similar Imbrian age, can also be fairly well modeled using simple magnetized disks at depth. Using these simple assumptions, the paleomagnetic pole positions have been determined. The modeling of these anomalies shows a cluster of paleomagnetic pole positions within a radius of about 35 degrees centered at (30S, 215E). These preliminary results are consistent with the hypothesis of a now extinct paleo-dynamo being responsible for magnetization of lunar crust. However, a more statistical analysis remains to be done over regions of weaker magnetic anomalies to be fully conclusive.
