40Ar/39Ar Dating of Muscovite from the Zhelande Au Deposit, Irtysh Tectonic Zone, Xinjiang and Its Geological Implications

    Abstract
  • BACKGROUNDThe Zhelande gold deposit is an important orogenic gold deposit in the Irtysh tectonic belt. This deposit is hosted in the ductile shear zone. Mineralization occurs as gold-bearing pyritized diorite veins, gold-bearing quartz veins, and gold-bearing pyritized phyllite. The mineralization is related to the brittle-ductile shear deformation. Muscovite, chlorite and other new minerals occurred in the shear surface.OBJECTIVESTo determine the metallogenic age by 40Ar/39Ar method.METHODSMuscovite 40Ar/39Ar dating was used to constrain the timing of ductile shear deformation and gold mineralization.RESULTSResults show that the plateau age of the muscovite is 295.4±1.6 Ma, suggesting that the ductile shear deformation and gold mineralization occurred at about 295 Ma, slightly earlier than the formation of the Duolanasayi gold deposit.CONCLUSIONSCombined with previous data, the orogenic gold deposits in the Irtysh tectonic belt of Xinjiang possibly formed at 295-270 Ma.
