1D Joint Inversion Analysis of VES and TDEM Soundings at Termas de Ibirá Region, Paraná Basin, Brazil

Abstract

In this work, the authors present results of 1D joint inversion of Vertical Electrical Soundings (VES) and Time Domain Electromagnetic (TDEM) soundings at Termas de Ibirá region, countryside of São Paulo State, Brazil. The objective is the analysis and comparison of the results of individual inversion and joint inversion. The VES results can solve the shallow layers (until the depth of 100 m) and the TDEM results solve the deep layers (between 100 - 1000 m depth). Therefore, the joint inversion explore the best of each method and it allows to make a more reliable interpretation about the local geology. Keywords: TDEM, VES, Joint inversion, Paraná basin, Termas de Ibirá, Brazil.
