    In general, stratigraphic sections are dated by biostratigraphy and magnetic polarity stratigraphy (MPS) is used subsequently to improve the dating of specific section horizons or to correlate these horizons in different sections of similar age. The presented paper shows, however, that the identification of a record of a sufficient number of geomagnetic polarity reversals against a reference scale often does not require any complementary information. The algorithm is based on the stochastic models of deposition/erosion and its magnetic record. A statistic test of the reliability of this solution is given. The application of this algorithm to various published magnetostratigraphic sections that included nine or more polarity reversals gave satisfactory results. The possible self-sufficiency makes MPS less dependent on other dating techniques.
