The sedimentary materials from the pyrite deposit were grouped into five 05 main lithofacies, including four claystone facies and one conglomeratic facies. A collection of writing tools that cover the many facets of English and French grammar, style and usage. Macroscopically, pyrite in thesematerials sedimentairss in crumbly and consolidated piles with aggregate pyrites in oolithic concretions, andglobular, cubic, octaedric, massive and fossiliferous forms. In which subject field?
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. A rock resulting from the consolidation of loose sediment that has accumulated in layers. Theparticle size distribution of clayey materials host rocks shows that they are essentially constituted of clay and silts fractions.
