韧—脆性剪切带对治岭头金银矿床的控制作用

The Controlling Ore ofDuctile-Brittle Shear Zone in Zhi-Ling-Tou Gold Mine

通过对基底变质岩构造变形的研究 ,认为矿区燕山期金银矿床的容矿构造是经韧—脆性剪切带中的里德尔裂隙系统演化而来的。并且在里德尔裂隙中局部形成了早期含微金交代石英脉。

through the study of structural deformation for base metamorphic rocks,the authors propose yanshanian ore-hosted fractures evolved from the system of “Ridel” fractures in ductile-brittle shear zone.and these fractures have filled previous auriferous plasement quartze vein.
