摘要
治岭头金银矿床矿体为含冰长石、蔷薇辉石的玉髓状石英脉体，矿石具环带状构造，围岩蚀变具典型的浅成低温热液蚀变特征，成矿流体是一种低盐度、近中性的还原性流体．矿床硫、铅、氢、氧、碳同位素研究表明，成矿物质主要来源于地下深部（甚至上地幔），成矿热液表现出低温热液演化特点．成矿作用与加里东晚期浅成岩浆侵入活动有内在的成因联系．
The ore bodies in Zhilingtou Au Ag deposit,Zhejiang Province, are chalcedonic quartz veins containing adularia and rhodonite The ores occur in circular zonal structure and grained,metasomatic and poikiloblastic texture Wall rocks are strongly altered and with typical features of epithermal alteration Ore forming fluid is low salinity,approximate neutral and reduced hydrothermal The S and Pb isotopes of the Au Ag doposit suggest that the ore forming materials are mostly from deep crust(down to upper mantle) The ore forming hydrothermal is derived from magmatic water and meteoric water,and evolves as low temperature hydrothermal suggested by H,O and C isotopes The mineralization of Zhilingtou Au Ag doposit are genetically associated with hypabyssal magmatic activities in Caledonian period It is a typical epithermal or sub volcanic hydrothermal Au Ag deposit
