A review of the studies results of paleomagnetic applicability of Precambrian crystalline rocks of the Ukrainian Shield.
The review of the data has been conducted of the long-term laboratory methods of studies of stability and origin of natural remanent magnetization (NRM) of Precambrian crystalline rocks of the Ukrainian Shield (USh). Generalization of the data gives weighty arguments for considering the Precambrian...

Orlova, M. The review of the data has been conducted of the long-term laboratory methods of studies of stability and origin of natural remanent magnetization (NRM) of Precambrian crystalline rocks of the Ukrainian Shield (USh). Generalization of the data gives weighty arguments for considering the Precambrian rocks of the Ukrainian Shield as promising objects for paleomagnetic studies. Statistical analysis has been made as to directions of NRM in exposures different by their age, composition and origin of crystalline rocks of the USh. It has been found that everywhere within the limits of the Ukrainian Shield in the exposures with magnetically stabile single-component magnetization of thermoremanent origin (according to laboratory and mineralogical criteria) NRM directions in contemporary coordinate system are distributed heterogeneously and are characterized by considerable dispersion. The most probable source of dispersion of NRM vectors within the limits of considered exposures of crystalline rocks of the USh is local tectonics, which produced reorientation within the area of the surface of initial magnetization of rocks.

The review of the data has been conducted of the long-term laboratory methods of studies of stability and origin of natural remanent magnetization (NRM) of Precambrian crystalline rocks of the Ukrainian Shield (USh). Generalization of the data gives weighty arguments for considering the Precambrian rocks of the Ukrainian Shield as promising objects for paleomagnetic studies. Statistical analysis has been made as to directions of NRM in exposures different by their age, composition and origin of crystalline rocks of the USh. It has been found that everywhere within the limits of the Ukrainian Shield in the exposures with magnetically stabile single-component magnetization of thermoremanent origin (according to laboratory and mineralogical criteria) NRM directions in contemporary coordinate system are distributed heterogeneously and are characterized by considerable dispersion. The most probable source of dispersion of NRM vectors within the limits of considered exposures of crystalline rocks of the USh is local tectonics, which produced reorientation within the area of the surface of initial magnetization of rocks. |
