The Jinchuan Ni-Cu sulfide deposit is ranked as the third largest magmatic sulfide deposit in the world, which contains 558 million metric tons of Ni resource and 354 million metric tons of Cu resource at Ni and Cu grades of 1.06% and 0.75%, respectively (Tang and Li, 1995). The Jinchuan ultramafic intrusion is only 1.34 km in outcrop, but the mineralized percentage of Ni and Cu is approximately 50%, which make it to be a representative style of “small intrusion to form large deposits” (Tang, 1990). The unique geological feature, huge economical values and significant prospecting potential of the Jinchuan Ni-Cu sulfide deposit have attracted many geologists (Tang, 1990; Chai and Naldrett, 1992a, b; Li and Ripley, 2011; Ripley et al., 2005; Song et al., 2006, 2009, 2012; Chen et al., 2013). More recently, according to the systematical studies of petrography, mineralogy, mining structures and PGE geochemistry of the Jinchuan deposit, Song et al. (2006, 2009, 2012) and Chen et al. (2013) proposed that the Jinchuan intrusion is originally comprised of two individual intrusions, as referenced to the Western intrusion and the Eastern intrusion, and the present appearance of Jinchuan intrusion is the consequence of post tectonic compression.
