摘      要：Multiple metallogenic types(skarn-type and vein-type)related to hypabyssal granites are found at the Huangshaping polymetallic deposit in the Nanling Range,South *** constrain the crystallization and mineralization processes of skarn formation,three generations of magnetite and pyrrhotite from the hydrous silicate stage,oxide stage,early quartz–sulfide stage,and late quartz–sulfide stage were *** geochemical compositions of magnetite and pyrrhotite were obtained by electron probe microanalyzer(EPMA)and in-situ ablation-inductively coupled plasma-mass spectrometry(LA‒ICP‒MS).The results show that there may be silicate inclusions in magnetite and interaction of wall rock occurred in the mineralization *** geochemical trends recorded in pyrrhotite show the influence of limestone during the crystallization of *** re-equilibration temperatures of Po I,Po II,and Po III are 420.46,380.45,and 341.81°C,respectively,which suggests a continuous evolution following the high-temperature W–Sn mineralized *** content change of Ni and V reflects a gradual decrease of oxygen fugacity from Mag I to Mag III,while the sulfur fugacity calculated from pyrrhotite gradually *** continuous skarn mineralization evolution process helps us to better understand the change of metallogenic environment in the retrograde stage of the Huangshaping deposit.
