International Journal of GeosciencesVol. Christoph Bosshard, Michel O. 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. Ni ratios of pyrites approximately 0.

Pyrite in sand fractions is associated with kyanite, rochee, rutile, diopside, muscovite and tourmaline the minerals whichrecognize the regional metamorphism. The sedimentary sedimentaifes from the pyrite deposit were grouped into five 05 main lithofacies, including four claystone facies and one conglomeratic facies.
