  abstract = {{A}zimuthal {R}esistivity {S}oundings ({ARS}), using the so-called "{A}rrow-type array" as proposed by {B}olshakov et al. were carried out in {C}entral {T}unisia, together with azimuthal resistivity tomography, because of the known anisotropic behaviour of the nearly vertical formations. {F}irst, the developments designed by {B}olshakov et al. are reviewed: they deal with the separation between the effects of anisotropy and of heterogeneities, the design of the {A}rrow-type array and the introduction of the azimuthal spectral analysis. {S}econd, the main methodological results obtained near {G}ouazine {L}ake are presented: (1) the clear effect of a quasi-vertical contact and (2) the characterisation of the anisotropic substratum below a thin superficial layer in one site close to the axis of the valley: the strike direction (alpha = 50 degrees {N}), and a rather high anisotropy coefficient (lambda approximate to 4) are determined. {A}nd lastly two directions for further developments are suggested.
