In geoelectrical investigation, one of the main electrical properties highlighted is electroresistivity, which refers to the difficulty that electric current encounters when propagating in a medium. In rocks, the mechanisms of current propagation can be electronic, related to the transport of electrons in the rock matrix, or ionic, related to the displacement of ions present in water in pores and fissures.
Electroresistivity data can be presented in several ways, such as profiles, sections, pseudo-sections and plans of isovalues of apparent resistivities. This variety of representations contributes to a more comprehensive understanding of the electrical characteristics of the investigated medium, offering valuable insights into the composition and structure of soil/rocks in an indirect way from the subsurface.
