Integrated multi scale archaeological analysis in Béni Mellal-Khenifra District (Morocco). The case of the fortress of Ighram Aousser

The fortress of Ighram Aousser is located in Morocco, 10 km W of M’rirt and 120 km S of Meknés, on the so-called mines route. The lack of an organic and complete documentation and a concrete need to acquire new data about unexplored areas have required a multi-methodological research including the analysis of historical sources, archaeological surveys, topographic investigations, laser scanner modelling and geophysical prospections. All data were stored in a Geographic Information System, which allowed spatial analyses and the creation of thematic maps. The integrated geoarchaeological approach has led to a new archaeological map providing an updated view of the rich archaeological heritage in that territory. The article also offers a complete account of the valorization processes, the international promotion of the site and its long-lasting mining tradition

Hydrochemical constraints between the karst Tabular Middle Atlas Causses and the Saïs basin (Morocco): implications of groundwater circulation

The karst Tabular Middle Atlas Causses reservoir is the main drinking-water supply of Fez-Meknes region (Saïs Basin) in Morocco. Recent analyses showed a decline in associated groundwater chemical quality and increased turbidity. To understand this hydrosystem, four surveys were undertaken during fall and spring, 2009–2011. Hydrogeochemical studies coupled with isotopic analyses (δ18O, δD and 222Rn) showed that the aquifers between the causses (mountains) and the Saïs Basin are of Liassic origin and at the southern extremities are of Triassic origin. Five recharge zones of different altitudes have been defined, including two main mixing zones in the south. Deuterium excess results suggest local recharge, while a plot of δ18O versus δD characterizes a confined aquifer in the eastern sector. 222Rn results reveal areas of rapid exchanges with an upwelling time of less than 2 weeks. A schematic conceptual model is presented to explain the groundwater circulation system and the behavior of this karst system
