Fig. 3From: Electrical conductivity of old oceanic mantle in the northwestern Pacific I: 1-D profiles suggesting differences in thermal structure not predictable from a plate cooling modelExamples of MT responses for Area A (left) and Area B (right) in terms of apparent resistivity (top) and impedance phase (bottom) sounding curves; x and y represent the geographical coordinate system. Symbols with error bars are the observed responses. The error bars indicate 95% confidence intervals. Solid lines are the responses predicted from a conductivity structure model that consists of the known 3-D topography over the estimated 1-D mantle structureBack to article page
