Abstract: Kangguer gold-polymetallic deposit with associated copper,lead,zinc and silver,lying south of the Tu-Ha basin in the eastern Tianshan Mountains,occur in the gigantic Qiugemintashi-Huangshan ductile compressional belt.The formation of the deposit is closely related to the evolution of this ductile compression belt and the deposit is considered as a hydrothermal altered rock-type gold deposit under the control of the ductile deformation belt.
The gold deposit occurs in the intermediate-acid rift volcanic rocks,was confined to the ductile compressional belt and the syntectonic pluton which formed during the orogeny as a result of the closing of the rift.The metallogenesis was synchronous with the tectono magmatic activity.
A trio model comprising volcanic rocks,syntectonic pluton and normal brittle-ductile-shear zone in one area is proposed for the ore deposit.Volcanic rock series provided most of metallogenic material,and syntectonic pluton supplied hydrothermal fluid,thermal energy and also part of metallogenic material while the normal brittle-ductile-shear zone formed the ore trapping structures."Three in one" is the necessary condition for the formation of ore deposit.
The normal brittle-ductile-shear zone,as a late product of ductile deformation is the main target for the prospecting of ore deposits.
