摘要
浙江治岭头金银矿床系燕山晚期火山热液作用之产物。随燕山期火山作用的演化,蕴藏在岩浆中的金、银等成矿物质逐渐进入岩浆后期热液中形成含矿热液。含矿热液沿火山塌陷断裂向上运移,由于物理化学障的作用,致使含矿热液大量涌人火山塌陷断裂的次一级张扭裂隙中成矿成晕。
The Zhilintou gold-silver deposit in Zhejiang is a product of Late YanshanJan volcanic-hydrothermal processes.With the evolution of Yanshanian volcanism, ore substances such as gold and silver in magmas gradually entered postmagmatic hydrothermal solutions to form ore solutions. The ore solutions moved up along volcanic collapse faults.The physicochemical barrier caused voluminous ore solutions to gush into secondary tenso-shear fractures of the collapse faults, thus forming gold-silver ore and their primary halos.
