| 摘 要： | 以锡铁山地区滩间山群火山-沉积岩为研究对象，利用岩石学和地球化学方法，探讨了滩间山群火山-沉积岩的成岩构造背景，旨在制约锡铁山铅锌矿床的成矿构造背景。结果表明，滩间山群火山-沉积岩的成岩构造背景为弧后盆地，且在地球化学方面，表现出从弧后盆地拉张初期至成熟期的连续演化特征。而锡铁山铅锌矿床则于弧后盆地拉张初期形成。

| Abstract: | The tectonic setting of volcanic and sedimentary rocks of the Tanjianshan Group in the Xitieshan region was studied using geologic and geochemical methods, aiming at better constraints on the tectonic setting of the Xitieshan lead-zinc deposit. The results show that the Tanjianshan Group formed in a back-arc basin environment. Moreover, geochemical results show continuous characteristics, from juvenile back-arc basin to mature. However, the Xitieshan lead-zinc deposit was formed at the early stage of the ba... |
