| 摘 要： | 论述了赞坎铁矿床的成矿地质背景和矿床地质特征。通过矿体形态特征、矿石结构构造、矿物组合分析,认为矿床的形成经历了铁质沉积和变质改造两个阶段,属于沉积变质型条带状硅铁建造矿床(BIFs)。通过磁测,发现矿区内磁异常主要为磁铁矿(化)体引起。圈定出多个隐伏异常体,为下一步找矿工作奠定了基础。

| Abstract: | The Zankan iron deposit in Tashikuergan county,Xinjiang,is tectonically situated in the Taxkorgan block within the Karakorum tectonic belt.Ore bodies are mainly hosted in the Proterozoic strata,the contact of the strata and felsite,in particular.7 layered or stratoid ore bodies are either north to west or north to northwest striking with obvious banded iron formation structure.The morphology,texture,structure,and mineral assemblage of the ores show that the iron ore formation underwent sedimentary diagenesis,metamorphism and late stage alteration.The deposit is of BIF-type.The aeromagnetic survey shows that the magnetic anomalies are mainly caused by magnetite ore bodies and the stronger magnetic anomalies are caused by industrial grade magnetite.Several hidden anomalous bodies will be the targets of future exploration. |
