| 摘 要： | 佛子冲铅锌矿床位于南岭成矿带中部南缘、博白-岑溪深断裂带北端。矿体产于奥陶系浅变质钙质碎屑岩和泥质灰岩中,主要受北北东向断层和岩体与地层接触面控制。本文通过对佛子冲铅锌矿床104号矿体中石英、闪锌矿和方解石包裹体均一温度的测定,对硫、铅、氢、氧等同位素的组成研究,以及根据闪锌矿Rb-Sr等时线年龄132±3 Ma,认为佛子冲铅锌矿属于与岩浆期后流体作用有关的燕山期中-高温热液矿床。 |

| Abstract: | Fuzichong Pb-Zn deposit is located in south central of the nanling metallogenic belt and northeast section of the Bobai-Cenxi metallogenic belt.The ore-bodies is occurrence in the Ordovician System shallow deterioration calcareous clastic rock and the argillaceous limestone,mainly be controlled by NNE-trending faults and stratigraphic contact zone with intrusion.Based on the study of geological characteristics,the mineral inclusion characteristic,homogenization temperature,the temperature of mineralsulfur isotope,stable isotopic compositions and the Rb-Sr isochron age of sphalerite of Fuzichong Pb-Zn deposit,concludes that the Fuzichong deposit is formed the medium-to-high temperature hydrothermal environment;the S-Pb-H-O stable isotope composition shows that the ore-forming fluid mainly comes from magmatic hydrothermal systems.Rb-Sr isochron age of sphalerite which is yielded 132±3Ma indicated that Fozichong Pb-Zn deposit formed in Yanshanian and belongs to magmatic-hydrothermal-type deposit. |
| Keywords: | geological features fluid inclusion stable isotope Rb-Sr dating of Sphalerite Fuzichong Pb-Zn deposit Guangxi province |
