葫芦峪金矿床位于华北克拉通南缘华熊地块崤山地体内，矿区出露地层为太古界太华群，未见中酸性岩体出露，金矿体主要受NW向断裂破碎带控制，以构造蚀变岩型为主，其次为石英脉型。成矿阶段可分为石英黄铁矿阶段、石英多金属硫化物阶段、石英碳酸盐阶段。石英多金属硫化物阶段是主要成矿阶段，该阶段形成的石英δD 值介于79‰～98‰，δ18 OH2O值变化范围为2．20‰～6．89‰，反映成矿流体主要为岩浆水，并有大气降水的加入。矿石中黄铁矿δ34 S值介于3．8‰～5．0‰，均值为4．0‰；闪锌矿δ34 S值介于4．0‰～5．0‰，均值为4．5‰。矿石中金属矿物206 Pb/204 Pb值为17．8184～18．0233，均值为17．9333；207 Pb/204 Pb值为15．5167～15．5484，均值为15．5362；208 Pb/204 Pb值为38．2264～38．3227，均值为38．2898。硫铅同位素组成表明，成矿物质主要来自于隐伏的燕山期花岗岩。
Huluyu Gold Deposit is located in Xiaoshan mountain body ,Huaxiong block in southern margin of the North China Craton .The outcroping stratum of the deposit is Taihua Group of Archaeozoic era .No sign of intermediate acidic intrusive bodies is observed .The orebody is mainly controlled by the NW trending fracture zone ,mostly made up of structural altered rock ,followed by the quartz vein .Ore-forming processes can be divided into quartz -pyrite stage , quartz-polymetallic sulfide stage and quartz -carbonate stage .Among them,quartz-polymetallic sulfide stage is the main stage for gold mineralization .In this stage,δD value of quartz ranges from -79‰to -98‰,δ18 OH2O value from-2.20 ‰to 6.89‰,indicating the ore-forming fluidsare mainly magmatic water with addition of meteoric water .δ34 S value of pyrite in ore is between 3.8 ‰ and 5 ‰,the mean of 4 ‰; δ34 S value of sphalerite is between 4 ‰ and 5 ‰,the mean of 4.5 ‰; 206 Pb/204 Pb value of ore minerals is between 17.818 4 and 18.023 3, the average is 17.933 3; 207 Pb/204 Pb is between 15.516 7 and 15.548 4,the average is 15.536 2; 208 Pb/204 Pb is between 38.226 4 and 38.322 7,the average is 38.289 8.Isotopic compositions of sulfur and lead show that ore-forming materials mainly derived from the Yanshanian granite .
