Some peculiarities of geological interpretation of gravitational and magnetic fields of Precambrian formations
Abstract
Precambrian platforms and shields, occupying the main part of the territory of the continents and storing in their bowels huge reserves of minerals, are not sufficiently studied geologically. Dissection and correlation of Precambrian strata by classical methods of paleontological, petrographic and structural-geological analysis are extremely difficult, as deeply metamorphosed and granitized rocks in many cases retain only relict textural and lithological features of the original geological formations. Geophysical methods, in particular, gravity and magnetic exploration, have great potential in studying the structure and reconstructing the history of development of Precambrian shields.
