Sources of lunar magnetic anomalies and their bulk directions of magnetization: additional evidence from Apollo orbital data.

摘要: A relatively high-amplitude magnetic anomaly directly detected with the Apollo 15 subsatellite magnetometer and centered near crater Gerasimovich on southeastern lunar far side is found to correlate location of a conspicuous Reiner Gamma-type swirl marking visible Zond 8 photograph. Examinations available direct indirect orbital magnetics measurements demonstrate that most strong anomalies occur in areas where morphologically similar markings are concentrated. Even though photogeologic studies indicate an impact-related origin for swirls, both swirls their associated tend exist preferentially or have been seismically modified. Modeling improved vector maps used infer 28 independent bulk directions magnetization isolated sources.
