Some remarks on resolving and interpretation of the short marine magnetic anomalies

Marine magnetic anomalies of the tiny wiggles (TW) type can be used to solve geohistorical and paleomagnetic problems. The model fields corresponding to Paleocene-Eocene anomalies in the northwestern Indian Ocean, which were formed during the fasts preading stage, were studied. For these fields, widely used interpretation methods were compared. The testing was performed with first the classical block model and then more complex models reflecting actual processes of oceanic accretion and magnetic field variations in the past. Spectral and statistical methods are used to estimate the magnetic anomalies(MA) resolving. Preprocessing of a set profiles based on the maximal correlation is considered.
