摘要
治岭头地区金银矿为浙江省内唯一的大型金银矿床。矿石矿物有银金矿、金银矿、辉银矿、碲银矿、辉铅铋银矿,少量黄铁矿、方铅矿、闪锌矿、黄铜矿。矿石结构构造为交代残余结构、填隙结构、乳滴状结构、致密块状构造、条带状构造、环带状构造。主要载金矿物为黄铁矿、石英。围岩蚀变为硅化、绢云母化、绿泥石化、黄铁矿化、方解石化、蔷微辉石化。硫同位素:1.47～10.57‰、硅同位素为:-0.1～-0.4׉。成矿温度287.5～260.4℃。成矿物质为多源,矿质聚集为多阶段的燕山中、晚期中温火山热液矿床。
Zhilintou Au-Ag deposit is the only large Au-Ag deposit in Zhejiang Province, of which minerals consist of electrum, argentite, petzite, maldonite and a little pyrite, galena, sphalerite, chalcopyrite, and is characterized by replacement relict, fissure-filling, etch, massive, concentric. Its minerals of gold carrier are pyrite, quartz. The wall rock alterations are silieification, sericitzation, chloritization, pyritizion, calitization, rhodonite. The mineralize temperature ranges from 287.5 to 260.4℃. δs is 1.47 to 10. 57%e, δ30Si - 0. 1 to - 0. 4%e. Metallogenic materials are multi- sources, the mineral gather has many phases deposit of mid-term late Yanshanian voleanic-hydrothermal deposit.
