Contribution of the 3D Geological Model to the Study of the High Basin Ziz Jurassic Aquifers Structure (Central High Atlas, Morocco)
2015
The high Ziz’s basin,
which is part of the Central High Atlas, contains Jurassic superficial and deep
aquifers. The information sheets are still fragmentary and insufficient because
of the basin’s large size and its complex geological structure. In order to
improve the knowledge of these aquifers and the determination of the structure
of aquifers, a 3D geological model was developed in this study. It was
constructed from information provided by 200 mechanical soundings and 81
electrical surveys and geological maps. Compiled holes were analyzed, coded and
integrated in the software Groundwater Modeling System 6.0 (GMS 6.0). For doing
this, five lithostratigraphic units were considered: the Domerian, the
Toarcian, the Aalenian, the Bajo-Bathonian and the Quaternary. The operation of
the 3D stratigraphic model allowed making it closer to the geometry of Jurassic
aquifers.
