“…ERT has been widely applied to these types of problems and many recent studies have shown its usefulness in defining geological structure, fault geometry, landslide boundaries (sliding surfaces), and deep water circulations (Naudet et al, 2008;Fazzito et al, 2009;Heincke et al, 2010;Jomard et al, 2010;Lebourg et al, 2010;Pánek et al, in press). In this study, ERT was useful because of 1) the relatively simple geological structure of the La Marbrière slope (monoclinal layers and vertical faults) that would result in simple inverted models, and 2) high resistivity contrast between limestone and mudstone or a fault zone and limestone that facilitate identification of stratigraphic boundaries to evaluate fault offsets (Caputo et al, 2003;Nguyen et al, 2007;Adepelumi et al, 2008;Schrott and Sass, 2008;Gelis et al, 2010).…”
