In magmatic-hydrothermal deposit, it is exsolving magmatic fluid that contributed to the concentration of ore metal and resulted in hydrothermal alteration and deposition (Hedenquist et al., 1994; Lowenstern et al., 1996; Harris et al., 2003; Yang et al., 2008). The primary magma-hydrothermal fluid was often represented by fluid in pre-mineralization veins. However, considering veinforming fluid had experienced water-rock interaction to some extent, properties of the vein fluid may be different from primary ore-forming fluid. Fortunately, unidirectional solidification texture is recognized as one of the geologic records during magmatic-hydrothermal transition (Lowenstern et al., 1996), and fluid exsolved from magma has properties of primary hydrothermal fluid that forming relevant ore deposit. Here, we discussed the UST quartz in Nannihu-Sandaozhuang Mo-W deposit hope to recognize the primary fluid and its evolution process. The main text is in 10pt Times New Roman.
