Doin, Paris, p. The sedimentary materials from the pyrite deposit were grouped into five 05 main lithofacies, including four claystone facies and one conglomeratic facies.
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. Ni ratios of pyrites approximately 0. Scientific Research An Academic Publisher. Macroscopically, pyrite in thesematerials is in crumbly and consolidated sedimentaired with aggregate pyrites in oolithic concretions, andglobular, cubic, octaedric, massive and fossiliferous forms.

Pyrite deposit of pK27, Douala sub-basin Cameroon, Central Africa was studied in a tropical lea setting physically and using X-ray diffraction and X-ray fluorescence spectrometry XRF in order to characterize the mineralization for his industrial utilization.
Pyrite in sand fractions is associated with kyanite, grenat, rutile, diopside, muscovite and tourmaline the minerals whichrecognize the regional metamorphism.
