| 摘 要： | 早元古代角闪岩相大型韧性剪切带和叠加其上的中生代脆性张裂破碎带共同组成的复合构造是治岭头金矿主要的控矿构造。成矿热液主要来自燕山期火山-岩浆活动。成矿物质主要来自上地壳下部的重熔岩浆。中生代火山岩盖层是避免矿液逸散的必不可少的屏蔽层。矿床类型属于燕山期火山-岩浆热液成因的后韧性剪切带型金矿。

| Abstract: | Several current genetic models of Zhilingtou gold deposit in Zhejiang province are re-viewed. The most important ore controlling structure of the deposit is a composite structure formed in a large ductile shear zone of early Proterozoic amphibolite -facies superimposed ty a Mesozoic bursting extinsion belt. The ore -horming tydrothermal fluids are related to the Yanshanian volcanic activity and magmatism. The ore -horming materials come mainly from the deepseated remelting magma in the lower part of upper crust. Mesozoic volcanic rocks acted as the indispensible screening cover preventing the fugitive metallogenic fluids. The de-posit is of a Yanshanian volcanic -magmatic hydrothermal type in back ductile shear zones |
