英文摘要We report new zircon U-Pb and pyrite Re-Os geochronological studies of the Yinjiagou poly-metallic deposit, sited along the southern margin of the North China Craton (SMNCC). In this deposit, pyrite, the most important economic mineral, is intergrown/associated with Mo, Cu, Au, Pb, Zn, and Ag. Prior to our new work, the age of chalcopyrite-pyrite mineralization was known only from its spatial relationship with molybdenite mineralization and with intrusions of known ages. The U-Pb and Re-Os isotope systems provide an excellent means of dating the mineralization itself and additionally place constraints on the ore genesis and metal source. Zircons separated from the quartz-chalcopyrite-pyrite veins include both detrital and magmatic groups. The magmatic zircons confine the maximum age of chalcopyrite-pyrite mineralization to 142.0 +/- 1.5 Ma. The Re-Os results yield an age of 141.1 +/- 1.1 Ma, which represents the age of the chalcopyrite-pyrite mineralization quite well. The common Os contents are notably low (0.5-20.1 ppt) in all samples. In contrast, the Re contents vary considerably (3.0-199.2 ppb), most likely depending on intensive boiling, which resulted in an increase of Re within the pyrite. This study demonstrates that the main chalcopyrite-pyrite mineralization occurred late in the magmatic history and was linked to a deeper intrusion involving dominant mantle-derived materials. This mineralization event might be related to the Early Cretaceous lithospheric destruction and thinning of the SMNCC.
