The A’erhada Pb-Zn-Ag deposit, located in Dongwuqi, Inner Mongolia, is one of the largest Pb-Zn-Ag deposits in this region. The geology and geochemistry of this deposit have been reported by Tao (2006), Gao and Qian (2005) and Zhang et al., (2007), but not much research address the ore forming fluids and their evolution in this deposit. The ore genesis is still open to debate. Based on the field observation, ore-microscopic, petrographic, microthermometric, LRM (Laser Raman Microsprobe) and H-O isotopic results of fluid inclusions in quartz from various mineralization stages, this paper discusses the characteristics and the evolution of ore-forming fluid.
