Apport de la gravimétrie à l’étude de la structure du bassin du Haouz (Maroc)

Abstract: The aim of the present study is to improve the knowledge of the Haouz basin structure using gravity data analysis. First of all, a residual anomaly map was computed from the Bouguer anomaly, greatly affected by an important regional gravity gradient. The calculated map provides information on the ground density variations mainly attributed to the top of the Paleozoic basement undulations under the sedimentary cover. However, in order to further study this map, it has been later analyzed with a method that allo… Show more

“…The figure 11 summarizes all horizontal gradient maxima of the residual anomaly as such as its upward continuations at different altitudes represented by different colours. Linear contacts can correspond to faults while circular ones can represent diapers limits or intrusive bodies [60,82,83,84].…”

“…The two directions NW-SE and NE-SW guide in surface the majority of hydrographic network as well as the main springs distribution which emerge from the northern atlasic border of Tadla plain. Indeed, had demonstrated the influence of the brittle tectonic on the drainage network organization and the spring resurgence because it accelerates the erosion and alteration processes and therefore the rivers development For a better results analyzing and in order to rule on strucural origin [70][71][72][73][74][75][76][77][78][79][80][81][82][83][84][85][86] of deduced lineaments from gravity data and radar images combination, we proceeded with a breakdown of the study area into tectonic sectors. Gravimetric lineaments and the ones deduced from the Sentinel-1image were correlated and compared for different parts of the study area ( Figu.13).…”

“…Ces formations reposent en discordance sur un substratum constitué d'un socle hercynien qui affleure au niveau du massif paléozoïque des Jebilets. La structure de ce massif ancien est relativement bien connue grâce aux nombreuses études qui y ont été menées (Felenc et al 1985, Boummane 1987, Bamoumen 1988, Leblanc 1993, Hibti 2001, El Harti et al 2004; pour le Haouz, des synthèses de l'ensemble des données géologiques, hydrogéologiques et géophysiques existantes ont été réalisées par Sinan (2000a), Sinan et al (2000b) et El Goumi et al (2010.…”

“…Cependant, les traits tectoniques profonds responsables de la structuration d'un aquifère ne peuvent pas être déterminés seulement par les données de forages; c'est pour cette raison que nous avons eu recours à la méthode gravimétrique appliquée avec succès dans différentes études hydrogéologiques (Najine et al, 2006;El Goumi et al, 2010;Ouerghi et al, 2013).…”
