漠滨脆—韧性剪切带型金矿床控矿构造研究

层间右旋逆冲脆—韧性剪切带构造控制漠滨金矿床。剪切带变形过程经历了早、中、晚3个阶段。而金矿化的形成和富集又与剪切带多阶段的演化密切相关,金矿化是剪切构造作用形成的。因此,剪切带既是控矿因素,又是重要的成矿机制,属层间逆冲脆—韧性剪切带型金矿床。

STUDY ON ORE-CONTROLLING STRUCTURES OF BRITTLE-DUCTILE SHEAR ZONE TYPE OF MOBIN GOLD DEPOSIT

Interlayer dextral brittle-ductile thrusting shear zone is the structure controlling the Mobin gold deposit, the shear zone had been undergone three stages of early .middle and late deformation processes. The formation and enrichment of Au mineralization is closely related to the multi-stage evolution of the shear zone. Therefore,the shear zone is not only an ore-controlling factor,but also an important metallogenic mechanism. The gold deposits are of interlayer brittle-ductile trusting shear zone one.
