摘要： 治岭头金矿位于浙江省遂昌县，是我国东南沿海的一座大型金矿床。该矿床围岩蚀变发育，类型有硅化、绢云母化、绿泥石化、黄铁矿化、方解石化和菱锰矿化。从矿体到围岩可以划分为4个蚀变带：强硅化带、弱硅化-黄铁绢英岩化带、绢云母化带和绿泥石化带。沿矿体走向，蚀变强度整体上呈波动性变化，与矿体呈透镜状产出特征一致。硅化、黄铁矿化、菱锰矿化与金矿化关系最密切，而且这些蚀变具有相似的变化趋势。绢云母化和绿泥石化与硅化的变化趋势不同，且与矿化关系不密切。另外，矿区还发育方解石化，且强度较弱。金矿化及围岩蚀变均发育在古元古界八都群变质岩中，未进入上覆中生代火山岩盖层，证明治岭头金矿成矿作用与中生代火山活动无关。定量计算结果显示：蚀变过程中Al2O3、TiO2、P2O5为惰性组分；SiO2、CaO、MnO、Au、Ag、Cu、Pb、Zn等为明显带入组分；Fe2O3、FeO、MgO、K2O、Na2O、Ba、Sr等为明显带出组分。根据围岩蚀变和稳定同位素分析，推断治岭头金矿原始成矿热液流体应是富含Si、Ca、Mn、Au、Ag、Cu、Pb、Zn等组分的岩浆热液，后期有大气降水的加入。

关键词: 治岭头金矿, 围岩蚀变, 蚀变分带, 质量迁移

Abstract: Located in Suichang, Zhejiang Province, Zhilingtou deposit is a large gold deposit on the southeastern coast of China. Its wall rock alterations are widespread in Zhilingtou gold deposit, such as silicification, sericitization, chloritization, pyritization, calcitization and siderite manganese mineralization. From ore body to wall rock, the alteration zone can be divided into quartz-rich, beresitization with quartz, sericite, and chlorite zones. In general, the alteration degree fluctuates with the distance to ore bodies, and forms a shape of lens just as the shape of an ore body surrounded. Gold mineralization is associated with quartz, pyrite, and rhodochrosite alterations. Quartz alteration, pyrite alteration, and rhodochrosite alteration degrees have a similar changing trend; while the sercite and chlorite alteration trend is different. In addition, the deposit develops a low degree of calcite alteration. Both gold mineralization and wall rock alteration occurred in the Paleoproterozoic metamorphic rocks of Badu Group, and did not enter overlying Mesozoic volcanic rocks, which indicates that the formation of the deposit has no relation with the Mesozoic volcanic activities. The elemental quantitative analysis showed that Al2O3, TiO2 and P2O5 were inactive components, SiO2, CaO, MnO, Au, Ag, Cu, Pb, Zn, etc. were gathered,and Fe2O3, FeO, MgO, K2O, Na2O, Ba, Sr, etc. were lost from the wall rocks in alteration process. According to the alteration features and stable isotope analysis, we conclude that the primitive hydrothermal ore-forming fluids of the deposit were mainly of magmatic water with enrichment in Si, Ca, Mn, Au, Ag, Cu, Pb, Zn, etc., and some meteoric water were added to the fluids in ore forming process.

Key words: Zhilingtou gold deposit, wall rock alteration, alteration zone, mass transport
