The author shows the possibilities of diagnostics and spatial parameterization of central type structures (SCT) by distributions of density contrast and singular points, modeled without aprioristic geologic-geophysical information. The author characterizes the intrusive-dome structures in the crust, formed during the introduction of intrusive bodies, and mantle SCT of plume nature, formed by extrusion of the asthenosphere under the bottom of the lithosphere in the zones of lithospheric plate subduction and in the regional stretching zones.
