Pyrite in sand fractions is associated with kyanite, grenat, rutile, diopside, muscovite and tourmaline the minerals whichrecognize the regional metamorphism. Deville, Abdelouahab Dehbi, Emmanuel Leriche.
Sandstone, shale, and limestone are sedimentary rocks. Pyrite deposit of pK27, Douala sub-basin Cameroon, Central Africa was studied in a tropical forest setting physically and using X-ray diffraction and X-ray fluorescence spectrometry XRF in order to characterize the mineralization for his industrial utilization.
The mineralogical compositions ofthese clayey materials indicate sedimentairew they are essentially kaolinitic and illitic, sedimentairee by goethite, quartz, pyrite, halloysite, anatase and rutile with hematite as accessory minerals.

The mineralization occurs along the low slopes of valleys inlight grey claystone facies situated on the bottom of outcrops with 80 to cm thickness.
Ni ratios of pyrites approximately 0. Macroscopically, pyrite in thesematerials is in crumbly and consolidated piles with aggregate pyrites in oolithic concretions, andglobular, cubic, octaedric, massive and fossiliferous forms.
