店房金矿床位于河南嵩县，经过勘探，提交金金属量12．62 t，伴生铅金属量26370 t，银金属量153．16 t。矿区δ34 S值为3．4‰～5．9‰，离散程度小，表明经过了均一化过程，也说明成矿物质是地幔和下地壳混合来源；铅同位素变化较小，206 Pb/204 Pb为16．9314～17．4121，207 Pb/204 Pb为15．1607～15．1753，208 Pb/204 Pb为37．3210～38．7644，铅同位素研究显示成矿铅来自地幔和下地壳，结合构造通道和矿体形态研究，可以预测在矿区爆破角砾岩外围东南深部存在隐伏岩体；矿区硫同位素显示，矿体中方铅矿δ34 S、近矿围岩方铅矿δ34 S、远矿围岩δ34 S具有不同特征，通过对钻探岩芯中方铅矿δ34 S测试可以为深部找矿勘探提供依据。

Dianfang gold deposit is located in Song County ,Henan,with exploration submitting metal quantity of gold 12.62 t,of lead 26 370 t and of silver 153.16 t.The value of δ 34 S is 3.4-5.9 in ore district,and its assembling characteristics prove that it came through homogenization process ,and that the source is a mixture of things consisting of the mantle and the lower crust;Changes of Pb isotope are relatively small ,with 206 Pb/204 Pb:16.9314-17.4121, 207 Pb/204 Pb:15.1607-15.1753,and 208 Pb/204 Pb:37.3210-38.7644.Pb isotope shows metallogenic lead came from the mantle and lower crust , and by studying geological structure and Pb isotope , hidden ore bodies in the southeast deep part of cryptoexplosive breccia peripherals can be predicted .the δ34 S of galena shows different characteristics of ore bodies from that of near wall rocks and far wall rocks .it can offer evidence for exploration in the deep part of de-posits by testing δ34 S of galena in the drill core .
