A tentative discussion on features of mafic-ultramafic?rocks and exploration methods in Pobei area of Ruoqiang, Xinjiang

Abstract: The Pobei area in Ruoqiang of Xinjiang has drawn much attention among geologists due to numerous magmatic sulfide nickel deposits discovered in this area. The Poyi deposit is a magmatic sulfide copper nickel ore deposit discovered recently. Due to its low grade ore and lack of high grade rich?orebodies, it can not meet?the?requirements?of mineral development. Based on geographic features of mafic-ultramafic rocks on the ntorthern slope, the authors summarized the features of magmatic sulfides already discovered, and made an analysis of favorable ore-forming conditions so as to carry out?ore?metallogenic prediction. In combination with the comprehensive methods for ore exploration which comprise geography, physical exploration, remote sensing and chemical exploration, the authors made a pretty good progress through practice: the anatectic penetration type Podong Ni deposit was discovered for the first time in Pobei area.
