Fig. 2From: Evidence for terrane boundaries and suture zones across Southern Mongolia detected with a 2-dimensional magnetotelluric transectData and penetration depth. a Apparent resistivity and b phase curves from the ssq-average for all individual magnetotelluric sites (grey lines) along the profile and their geometric mean (blue lines). c The penetration depth of electromagnetic signals is calculated, using the real part of the C-response (blue line), based on a conductivity profile obtained from a 1-D inversion of the ssq regional impedance average, and the skin depth (dashed black lines), based on a homogeneous model of 10 Ωm and 1000 ΩmBack to article page
