A rock resulting from the consolidation of loose sediment that has accumulated in layers.The sedimentary materials from the pyrite deposit were grouped into five 05 main lithofacies, including four claystone facies and one conglomeratic facies. The mineralization occurs along the low slopes of valleys inlight grey claystone facies situated on the bottom of outcrops with 80 to cm thickness.The mineralogical compositions ofthese clayey materials indicate that they are essentially kaolinitic and illitic, followed by goethite, quartz, pyrite, halloysite, anatase and rutile with hematite as accessory minerals.This website uses cookies to improve your experience while you navigate through the website.
