A rock resulting from the consolidation of loose sediment that has accumulated in layers. 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. Macroscopically, pyrite in thesematerials is in crumbly and consolidated piles with aggregate pyrites in oolithic concretions, andglobular, cubic, octaedric, massive rocues fossiliferous forms.
Theparticle size orches of clayey materials host rocks shows that they are essentially constituted of clay and silts fractions.
Pyrite in sand fractions is associated with kyanite, grenat, rutile, diopside, muscovite and tourmaline the minerals whichrecognize the regional metamorphism. FAQ Frequently asked questions Display options.
