Massive tungsten-tin, rare and rare earth metals ore deposits were formed with the widespread granite magmatic activity in early Yanshanian period in the eastern Nanling region. Recent studies indicate that the Yanshanian highly differentiated-granite formation is closely related to the deposits of tungsten and tin, rare and rare earth metals mineralization in the region(Xiao Huiliang et al., 2011). The Yanshanian granite is mainly composed of small rock mass. The related ore-forming magmatic rocks are acidic (SiO2 content: 72~78%), F-rich, with more than 74% super acid granite and middle-to-excessive-aluminum basic granite. The magmatic rocks include three major types of granites:muscovite, dimicaceous and garnetiferous. The formation age of the magmatic rocks is ~150-165Ma.
