| 中文摘要: |
| 虽然红墩铅锌矿床与铁木尔特铅锌矿床均产于新疆阿尔泰山南缘中部的克兰裂谷盆地,且二者的矿体产状与地层走向一致,具有明显的纹层状构造,但是在某些主要地质特征上,二者却存在显著的差异.例如,前者赋存于中泥盆统阿勒泰镇组的沉积碎屑岩,与海相基性火山岩有关,表现为锌多铅少,不含铜,且闪锌矿为含铁较少的低温闪锌矿;而后者却赋存于下泥盆统康布铁堡组的火山碎屑-碳酸盐岩中,与海相酸性火山岩有关,表现为铅多锌少,富含铜,且闪锌矿为含铁较多的高温闪锌矿.综合对比研究表明,红墩铅锌矿床属于SEDEX型铅锌矿床,而铁木尔特铅锌矿床则属于VHMS型铅锌矿床. |
| 英文摘要: |
| Hongdun and Tiemuerte lead -zinc deposits are all located in the Kelan rift basin of the middle part of the southern edge of Altai mountain, Xinjiang. Ore occurrences of two deposits are the same as the strata with obvious laminated bedding structure. There also exist some apparent differences between two deposits in geologic characteristics, For example, host rocks of Hongdun deposit is sedimentary clastic rock of Middle Devonian Aletaizheng Formation. Mineralization was related with marine basic volcanic rocks. There are more zinc - bearing minerals than Deadbearing minerals, and no copper - bearing mineral in the ores, Sphalerite is a low temperature one with lower iron, Host rock of Tiemuerte deposit is volcano elastic - carbonate rock of lower Devonian Kangbutiebao Formation. Mineralization was related with marine acidic volcanic rocks. There are more lead - bearing minerals than zinc - bearing minerals, and more copper - bearing minerals ores. Sphalerite is high temperature ones with higher iron. Through the contrast study, it is thought that the Hongdun lead -zinc deposit belongs to SEDEX type, and the Tiemuerte lead -zinc deposit belongs to VHMS type. |
