| Study on the Genesis of Kanggur Gold Deposit Based on the Discordance of the Metallogenic Epoch and Deformation Time |
| The Kanggur gold deposit, located in the northern margin of Tarim plate, outcrops in the middle part of Quigemingtashi-Huangshan ductile shear zone, so it is, in the long time, considered to be the gold deposit of shear zone type. However, the preliminary study of isotope geochronology indicates that the metallogenic epoch is discordant with the deformation age. Metallogenic epoch of the Kanggur gold deposit is about 290 Ma while deformation age of the Quigemingtashi-Huangshan ductile shear zone is about 225～236 Ma.If the metallization is considered to occur in Heicynian period, ductile shear deformation occurred in the middle-late Indo-Sinian period is not the key factor of Kanggur gold deposit metallization and it is also limited on the alteration of the gold deposit. Therefore, Kanggur gold deposit is not that of shear zone type. |
