This volume presents some of the first results of a cooperation between the Geology Department of the Chouaib Doukkali University at EI Jadida in Morocco and the Geologic-Palaeontologic Institute of the Ruprecht-Karls-University at Heidelberg in Germany. The main objectives of this cooperation are the understanding of the emplacement of magmatic bodies, related dykes, and mineralizations. In order to unravel the Pan-African tectonic evolution in the Anti-Atlas (Fig. 1), which led to the genesis of this magmatism and mineralization, detailed structural, microscopic and AMS work, is applied. In addition to the scientific and economic aims, the cooperation project intends to develop the general knowledge in economic and structural geology, in close cooperation with University institutions and mining companies. The first initiative from the Morroccan side was taken by Dr. Ali Bajja of EI Jadida. He is now Professor at the Cadi Ayyad University at Marrakech but still contributing actively to the cooperation project. This is documented very weil by his review paper on the Pan-African volcanism in the Anti-Atlas. More detailed studies concern the eastern Saghro in the eastern Anti-Atlas, where the cooperation between Drs. Ennih and Errami of EI Jadida and the working group at Heidelberg resulted in a number of artieles on the emplacement and evolution of granitoid plutons in the Imiter area, elose to the Imiter mine (Fig. 2). Applied methods range from petrography, geochemistry, mineral chemistry to structural and microstructural work and the application of magnetic methods. In particular, the anisotropy of the magnetic susceptibility (AMS) showed once again its high potential in determining and quantifying strain even in such rocks, where strain markers for conventional methods are lacking. With regard to the regional importance of the results, Figure 1 shows the general situation of the Anti-Atlas in the frame of the late Neoproterozoic orogenic belts, called Pan-African in present Africa, which built up the supercontinent of Gondwana. On the map, the Anti-Atlas appears to be at a marginal position with regard to [...] |
