Abstract

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.

Highlights

The study area extends from the far east of the Central High Atlas to the western part of the High Atlas Oriental.How to cite this paper: Nouayti, N., Khattach, D. and Hilali, M.

This paper presents a 3D geological model the height of Ziz basin by integrating all geological data from drillings, electrical surveys and geological maps
The elaborated three-dimensional model (Figure 3), based on the of available geological data and electrical surveys allowed us to visualize the architecture of the High Ziz basin, to realize out geological sections in all directions and at any location of the model and to monitor changes in depth Jurassic aquifers (Figures 3-8)
