Some peculiarities of geological interpretation of gravitational and magnetic fields of Precambrian formations
Authors:
Abstract
Precambrian platforms and shields, occupying the main part of the territory of the continents and containing in their interiors huge reserves of minerals, have been insufficiently studied geologically. The subdivision and correlation of Precambrian strata by classical methods of paleontological, petrographic and structural-geological analysis are extremely difficult, because deeply metamorphosed and granitized rocks in many cases retain only relict textural-structural and lithological features of the original geological formations. Geophysical methods, in particular gravity and magnetic exploration, have great potential for studying the structure and reconstructing the development history of Precambrian shields.
