Tensor CSAMT survey over the Sulphur Springs thermal area valles Caldera, New Mexico, U.S.A., Part II: Implications for CSAMT methodology

摘要

The resistivity model for the Sulphur Springs area in the companion paper (Part I) plus the availabil- ity of overlapping controller-source audiomagnetotel- luric (CSAMT) and magnetotelluric (MT) data has allowed study of far-field to near-field transitions, source field geometries over the survey area, and scalar-tensor impedance discrepancies.
