RELATION OF MAGNETIC-PROPERTIES OF THE ROCKS OF THE UKRAINIAN SHIELD TO THEIR COMPOSITION AND METAMORPHISM

A magnetization map was compiled for the Ukrainian Shield. The magnetization contours generally resemble those for the anomalous magnetic field, and this is explained by the coincidence of the directions of the induced and remanent magnetizations for most of the shield rocks. The magnetization map makes it possible to establish a correlation between the magnetization distribution in the shield rocks and the history of evolution and peculiarities of the structural blocks of the shield. In order to study the physical properties and mineral composition of rocks within the areas of two regional anomalies, correlation of magnetization with original composition and degree of metamorphism and granitization were investigated.
