Skarn deposits are widespread in the world and represent important source of Cu, W, Fe, Pb-Zn, Ag, Au, and Sn (Meinert et al., 2005). Skarn metallogenesis is a dynamic process, and the development of a particular skarn deposit depends on parameters such as the host rock types, geochemistry of the causative intrusions and the local tectonic history (Ciobanu and …
