The Pan-xi area is located in middle of the Pan-xi Great Rift Valley, which witnessed multiple complicated geological events and remains lots of geological phenomenon and bodies. Influenced by the tectonicmagmatic activity in the ELIP, a lot of mafic-ultramafic layered intrusions hosting Fe-Ti oxide deposits and Cu-Ni(PGE) magmatic sulfide mineralization occur close to the S-N-trending fractures. The Hetaoshu just represents a magmatic sulfide deposit with rich-PGE, which located in tectonic intersectant place on the sub-fractures of An-Ning River-Yimen deep fault and Hekou duplex anticline. The Hetaoshu deposit is composed of west and east dykes, controlled by the north-east and south-north compressor-shear structure, the ore-bearing intrusion intruded the Lower Proterozoic Hekou Formation and Upper Proterozoic, which are quartzite, quartz breccia, garnet muscovite schist, gabbro and gabbro diabase, respectively.
