Guzhikov A.Yu. (2019) General Magnetostratigraphic Scale: Present Status and Outlook of Development // In: Nurgaliev D., Shcherbakov V., Kosterov A., Spassov S. (eds) Recent Advances in Rock Magnetism, Environmental Magnetism and Paleomagnetism. Springer Geophysics. Springer, Cham. P. 343-351.

Geomagnetic Polarity Time Scale (GPTS) and Generalized Magnetostratigraphic scale (GMSS) which is in use in Russia synthesize the paleomagnetic data of the world. Ideally, there should be only one global scale of geomagnetic polarity (GPTS or GMSS, or a new scale constructed through their synthesis). All other paleomagnetic scales may be of local or regional (possibly, sub-global) character. But since the GPTS chrons are referenced to the International Stratigraphic Scale (ISS), and the GMSS magnetozones—to the General Stratigraphic Scale (GSS), the necessity of equiponderant coexistence of the GPTS and the GMSS will persist until all the correlation problems between the two scales are solved or until these are merged together. Practical use of a domestic version of paleomagnetic scale for geologic investigations requires construction of an updated and verified GMSS version—with regard to recent magnetostratigraphic data. Simultaneously with the process of data verification, procedural problems should be solved which may arise while further development of the General Magnetostratigraphic Scale: to continue improving the GMSS hierarchic structure on the quantitative basis, to take into account the diachronism of biostratigraphic boundaries for integration of a paleomagnetic scale with detailed biostratigraphic units, to develop theoretical grounds for the use of paleomagnetic criteria for identifying the boundaries of common stratigraphic units.
