| 摘 要： | 矿体直接产于一套爆裂岩、爆碎角砾岩和爆破角砾岩组成的隐爆岩中。矿石矿物有黄铁矿、方铅矿、闪锌矿、少量黄铜矿。矿石结构构造为交代残余结构,包含结构,角砾状、浸染状、网脉状构造。围岩蚀变为碳酸盐化、绢云母化、绿泥石化、黄铁矿化。成矿温度100°C～400°C。成矿时代燕山晚期。硫同位素为:3.1‰～7.59‰,铅同位素206Pb/204Pb:17.986～18.11、207Pb/204Pb为15.602～15.639。

| Abstract: | The orebodies are hosted in a suit of concealed explosion rocks consist of burst rock, burst breccias and explosive breccias.Ore minerals consist of pyrite, galenite, sphalerite and a little chalcopyrite.Ore is characterized by replacement remnant texture, including structure, breccias structure, disseminated structure and vein structure.The wall rock alterations include carbonation, sericitization, chloritization and pyritized.The metallogenic temperature ranges from 100°C to 400°C, the sulfur isotope composition is within the range of 3.1‰ to 7.59 ‰, The 206 Pb/204 Pb and 207 Pb/204 Pb ratios vary in ranges of 17.986~18.11 and 15.602~15.639 respectively. |
