多角铅锌矿成矿温度拟定

Metallogenic temperature formulation of Duojiao lead-zinc deposit

多脚铅锌矿位于多脚村附近,矿区出露地层为古生界马邓岩群外麦地岩组b段和c段,其中,b段以石英砂岩为主,c段以千枚岩为主。该矿床方铅矿-闪锌矿硫同位素地质温度研究结果表明,其温度范围在267℃~319℃之间,均值292.5℃,其变化幅度不大,该计算温度较伴生矿物方解石包裹体温度高。方铅矿-闪锌矿地质温度计计算结果可信,有较好的应用前景。

Stratum of Duojiao lead-zinc mine, located near Duojiao village, are Paleozoic Madeng group-complex b and c segment, b segment mainly charactered by quartz sandstone and c is phyllite. Sulphur isotope geological thermometer indicated that temperature varies from 267℃ to 319℃ of Duojiao lead-zinc mine, which higher than Inclusion temperature from calcite. calculating temperature of Galena and sphalerite Sulphur isotope geological thermometer Can be trusted and It has a good application prospect.
