| 摘 要： | 黄岗梁矿床是我国北方唯一的一处锡铁共生大型矽卡岩型矿床，苏大沟是黄岗梁矿床NE向延伸的铜铅锌矿点。黄岗梁矿床围岩、蚀变围岩、赋矿矽卡岩以及不同矿体石榴子石稀土元素的总特征体现了岩浆和岩浆水、围岩和大气降水对成矿的综合影响。靠近岩体则较多地体现了岩浆和岩浆热液作用；远离岩体则围岩地层和大气降水作用增强；从贫矿体－富矿体，从早阶段到晚阶段，大气降水对成矿的贡献增大，晚期又叠加了岩浆和岩浆热液成矿作用。黄岗梁铁锡矿床的REE配分曲线类型多样、变化较大，充分显示了成矿流体的多来源和多期次叠加成矿的稀土元素特征。苏木沟铜铅锌矿点具有岩浆热液稀土元素特征。稀土元素的研究初步建立了华北北缘黄岗梁式矽卡岩型矿床稀土元素配分模式。

| Abstract: | The Huanggangliang deposit is the large Fe-Sn paragenic one in northern China. The REE geochemistry of strata, altered rocks, ore-hosting skarn and garnet fro m various orebodies indicates that the comprehensive process of magma, magmatic water, wall rocks and especially meteoric water is responsible for metallization . The contribution of magmatism to metallization tends to increase toward intrus ive, but the contribution of strata and meteoric water to metallization tends to increase away from intrusive. The effect of meteoric water on metallization ten ds to be intensified from barren ore to rich ore. In the late stage, magmatic hy drothermal process was superimposed on metallization. The various REE patterns s ymbolize the multi-source of fluid and multi-phase metallization.The REE patte rns are the magmatic hydrothermal characteristics in Sumugou Cu-Pb-Zn deposit. The result of REE geochemistry primarily establishes the REE pattern model for the type of Huanggangliang skarn deposit. |
