ABSTRACT
We have investigated the morphology of the negative regional magnetic anomaly of Arctic Urals. This magnetic anomaly spatially coincides with structures of Predurals depression. In this paper we applied the method of construction 3-D surfaces using magnetic data. We suggest modified iterative local correction method for solving structure magnetic inverse problem. The 3D-magnetic model of the Arctic segment of the Earth crust has been constructed. The main elements of subsurface structure at whale latitudes are preserved.
