摘要

 
    

     Located in the Huashan-Xiong’ ershan block on the southern margin of the North China craton, the Yinjiagou pyrite-polymetallic deposit in Henan Province is the largest pyrite-polymetallic deposit in the East Qinling orogenic belt. The deposit is characterized by abundant pyrite resources and complex paragenetic and associated elements, which is different from most molybdenum deposits marked by the assemblage of molybdenum and tungsten in the East Qinling area. The dating data obtained in this study indicate that both skarn-and porphyry-type ore bodies of the Yinjiagou deposit formed approximately 143 Ma ago during the Early Cretaceous.
