Iourirne gold deposit is located in Tagragra of Akka inlier, 260 km to the southeast of Agadir, (Western Anti-Atlas). The gold mineralization occurs in quartz veins associated with shear zones occurring in East-West direction and cut across the Early forming process of Neoproterozoic formations. This study aims to characterize supergene alteration characterization of Iourirne gold mineralization, by macroscopic, microscopic observations, chemical analysis of major elements, analysis of the correlation matrix and analysis in Principal Components (PCA).
The main results are as follows:
- The mobility of a number of chemical elements such as Ti, Fe, P, Ca, Mg, Mn.
- The development of Hematitization phenomenon of supergene origin.
- The abundance of metallic minerals such as magnetite, hematite, covellite, malachite, azurite and sphalerite…
- The oxidation of sulphides including arsenopyrite, pyrite, chalcopyrite…
