The North Himalaya is located between the IndusYarlung Zangbo Suture Zone and the South Tibet Detachment System. There are many Au (–Sb), Sb, and Pb–Zn (–Ag–Sb) deposits or occurrences. Due to the scarce research on mineral exploration and metallogeny in this region, these deposits are small scale and their genetic types are controversial, including SEDEX (Li et al., 2002), epithermal (Qi et al.,2008; Zhang et al., 2010), hydrothermal vein (Hou and Cook, 2009), and orogenic (Sun et al., 2010). The Zhaxikang Pb–Zn–Ag–Sb deposit is the largest deposit in the North Himalaya, containing 1.27 Mt of Pb + Zn metal (average grade of 5.3%), 0.14 Mt of Sb metal (average grade of 1.1%), and 1800 t of Ag metal (average grade of 110 g/t). To gain a sound understanding of the characteristics of mineralization in the North Himalaya, it is necessary to study the largest Pb–Zn–Ag–Sb deposit, at Zhaxikang, in detail.
