Abstract: Nianzigou molybdenum deposit is located in the western part of the Xilamulun molybdenum metallogenic belt at the north margin of North China Craton, which is a medium-sized typical quartz vein type deposit. The ore veins mainly occur in the NNW, NW trending faults developed in the monzonitic granite-moyite intrusions of Early Yanshanian. The hydrothermal mineralization can be divided into four stages:pyrite ±molybdenite+quartz(Ⅰ), molybdenite+pyrite ±chalcapyrite+quartz (Ⅱ), chalcopyrite+pyrite ±sphalerite+quartz (Ⅲ), and quartz ±calcite (Ⅳ). The systematic study on petrography of fluid inclusions, fluid inclusion assemblages,and micro-thermometry shows that the primary ore forming fluids are of high temperature (490-550℃),low-medium salinity NaCl-H2O type solutions (10%-18%); their δ18OH2O-SMOW(2.21‰)and δDH2O-SMOW(-68.9‰)imply that they were originally from magmatic activities, and continuously up-rose and gathered into ore-controlling faults; later with the gradual decrease of temperature and pressure(380-460℃, 26-40 MPa→360-420℃, 25-30 MPa), the state of immiscible two-phase appeared, and the fluid began to boil, which resulted in the deposition of large amounts of Mo; at the late stage of the fluid evolution, the residual solution mixed with meteoric water. Nianzigou Mo deposit is a medium-high temperature magmatic hydro thermal deposit in Early Yanshanian.

Key words: Nianzi gou molybdenum deposit, quartz vein type, fluid inclusion, evolution of ore-forming fluids, Inner Mongolia Autonomous Region
