The objective of this study is the analysis of the south of Chicontepec Paleocanyon (PC) and the relation of electromagnetic anomalies. For this purpose, we measured, processed, and interpreted 16 broadband magnetotelluric (MT) soundings, disposed of in an orthogonal profile that covers the inside and the boundaries of the Paleocanyon. We performed a 3-D inversion of the data set (ModEM) using the range of periods between 10−3–102 s. In addition, we compared the result of 3-D inversion and the interpolation of 1-D inversion in their invariant rotational along the profile, where it is watched that they are similar in the resistivity anomalies and geological structures. The interpretation of the 3D resistivity inversion model shows the heterogeneous geometry and boundaries of the Paleocanyon and the contact between sediments and the top of the basement. Furthermore, based on the resistivity contrast, the information from wells-drilled, and seismic sections, it is possible to delimitate some anomalies that perhaps have the probability of hydrocarbon existence. • Comparison of sections 3D MT inversion and seismic in the Chicontepec Paleocanyon. • Resistive contrasts were correlated to the geological structures and the basement. • 3D Magnetotellurics is a powerful technique for oil and gas exploration • MT surveying can help seismic information to detect oil/gas reservoirs [ABSTRACT FROM AUTHOR]
