deposits have been studied as a unique ore type by numerous geologists for over a hundred years. It has been well established that most skarn deposits are closely related to granitoids and constitute a major source of the world’s Fe, Cu, Au, W, Sn, Pb and Zn. Two distinctly different alteration types occurred in most skarn deposits, including an early prograde stage with anhydrous minerals forms from relatively high-temperature, hypersaline liquid and a later retrograde stage with hydrous minerals forms from lower temperature, lower salinity fluids, and the main ore minerals in skarn deposits formed during the later retrograde stage (Meinert et al., 2003). As with any recently emergent isotopic geochemistry and in situ analysis techniques, researchers obtained some new understandings about skarn deposits. This short review reports some of these progresses.
