A study of the Rima Sirsalis lunar magnetic anomaly

摘要: Abstract The source of the lunar magnetic anomaly associated with Rima Sirsalis linear rille has been modelled using vector field intensities due to arbitrary uniform magnetization in a rectangular prism. It is shown that order match Apollo 16 subsatellite data, surface near must have vertical 6–9 × 10 −3 G if flux leakage from gap crust dimensions rille. This more than one magnitude larger any sample, but comparable high recently deduced for Reiner γ formation Oceanus Procellarum. An alternative explanation and its surroundings are site contrast ∼10 −5 – −4 which at least as wide extends depth tens kilometers crust. A wider reduces required (or depth) proportionately, since first altitude proportional dipole moment per unit length.
