Contribution de la gravimétrie à l'étude de la structure de la plaine de Mornag (nord est de la Tunisie): implications hydrogéologiques

Géométrie de l’aquifère du Haouz oriental et Tassaout amont, Maroc occidental: approche géophysique et hydrogéologique

“…Ces failles, qui mettent en contact des blocs de densités différentes, se présentent sur une carte gravimétrique sous forme de zones de gradients qui marquent la transition entre les deux blocs. L'application de la technique d'analyse des contacts fondée sur le calcul du gradient horizontal couplé au prolongement vers le haut permet la localisation de ces discontinuités et la détermination de leur pendage (Archibald et al 1999, Najine et al 2006, Chennouf et al 2007, El Gout et al 2009, Abderbi et Khattach 2010, Aqil et al 2010, Farhat et al 2010.…”

Contribution of Gravity Data for Structural Characterization of the Ifni Inlier, Western Anti-Atlas, Morocco: Hydrogeological Implications

“…The Ifni inlier, which provides a window into the Precambrian basement of the Anti-Atlas, is composed of crystalline rocks hosting fissured aquifers, where groundwater is contained in tectonic discontinuities such as faults, fractures, and alluvial depressions. To map the tectonic faults and their influence on groundwater dynamics in the Ifni inlier, indirect geophysical methods are needed due to the presence of a thin Quaternary cover obstructing geological observations and surface data [9][10][11][12][13][14][15]. This study aims to use gravity data analysis to create a detailed map of the fault systems affecting the study area for hydrogeological reconnaissance purposes [11][12][13][14][15].…”

This study aims to use gravity data analysis to create a detailed map of the fault systems affecting the study area for hydrogeological reconnaissance purposes [11][12][13][14][15]. The residual gravity data, derived from subtracting the regional anomaly component from the Bouguer anomaly map, is analyzed using different transformation techniques to analyze the gradient of the gravity field [13,[16][17][18][19][20][21][22][23][24][25][26].…”
