The main objective of this study was to investigate copper-Nickle-Iron bearing rocks of the northern Kenya, and understand their mode of formation. The area of study is bounded by latitudes 2˚52'00"N and 1˚52'00"N and longitudes 37˚19'00"E and 37˚36'00"E, South West of Marsabit town. The methods involved geological field mapping between September, 2020 and December 2020. Elemental analyses of the samples were done using an XRF. Pearsonian correlation on the analyzed elements was done using Oasis Montaj 8.4. Fabric8 software was used to analyze structural data. The area comprises metamorphic, igneous and sedimentary rocks. Metamorphic rocks include biotite hornblende gneisses, biotite gneisses, biotite muscovite gneisses and marbles. Basalts of different mineralogy were also found in the area. Colluvium and alluvium sediments were found covering some of the metamorphic rocks in some areas. Malachite occurs in gneisses in the central part of the area. The area has undergone deformation, which includes jointing and folding. The fold axis trend in the North-South direction and plunges to the southern part of the area. Correlation of the elements shows that there is a positive correlation of Copper-Nickel-Iron. This indicates similar mode of delivery within the host rocks. Kriging indicates spatial distribution of these elements within the study area. The average size of distribution can easily be computed from the maps produced by kriging.

Sebaran cebakan bijih besi di Indonesia banyak ditemukan di Jawa Timur, Kalimantan Selatan, Sumatera Barat, Sulawesi Tengah, dan Sulawesi Selatan. Daerah di Sulawesi Selatan yang memiliki sumber daya bijih besi yang melimpah yaitu Kabupaten Bone, Sulawesi Selatan tepatnya di Dusun Pakke, Kecamatan Bontocani. Tujuan dilakukan penelitian ini adalah mengetahui jenis mineral pembawa bijih besi serta asosiasinya dan mengetahui paragenesis atau urutan pembentukannya. Proses pengambilan data meliputi pengamatan secara langsung singkapan bijih besi yang muncul ke permukaan dan melakukan pengambilan sampel dengan metode chip sampling dan rock sampling. Analisis laboratorium menggunakan analisis mineragrafi untuk mengetahui mineral pembawa bijih besi dan tekstur mineral bijih dan Analisis X-Ray Diffraction (XRD) untuk menganalisis mineral pembawa bijih besi serta asosiasinya. Dari hasil penelitian diperoleh mineral pembawa bijih besi berupa magnetit, hematit dan geotit dengan asosiasi mineral berupa mineral sulfida yaitu pirit dan mineral pembawa bijih mangan berupa pirolusit dan manganit. Tekstur mineral bijih yang dijumpai yaitu intergrowth, granular, replacement dan open space filling. Berdasarkan pengamatan tekstur bijih paragenesis endapan bijih Daerah Pakke berturut-turut dimulai dari terbentuknya mineral yaitu magnetit, manganit, pirolusit, hematit, pirit dan goetit.
