AB  - Electrical resistivity and Very Low Frequency electromagnetic profiles (VLF) were introduced for a litho-structural study in the locality of Douira, located in the Errachidia basin. The electrical reading was carried out with a Schlemberger type device. The VLF profiles were implemented with a different length reaching 1600 m and profile lines oriented in the direction NNW-SSE and N-S. The VLF measurements were obtained using an Iris T-VLF instrument and the data filtering was carried out using the KHFFILT software. The Karous-Hjelt filter was applied to the real component of the secondary electromagnetic field. The qualitative interpretation of the resistivity results has shown that the formations identified in the locality of Douira are more resistant than those encountered around Ain Al Atti, this difference is the salinity coming from marly formations with intercalation of gypsum deep in the vicinity by Ain Al Atti. The semi-quantitative interpretation of the VLF results showed the presence of a main fracture zone, oriented NW-SE, which feeds the Ain Al Atti source.
