Geological reasons for the difference of magnetic fields of the dome-shaped structures of the Allarechensk ore district
Abstract
The structural plan of the Precambrian is characterized by a wide development of the so-called dome-like structures - gneiss-migmatite domes, in the central parts of which the most intensively granitized rocks are exposed. When mapping such structures in recent years widely and successfully used materials of airborne and ground magnetic surveys. ...
