摘　　要：红墩铅锌矿床位于克兰裂谷盆地,形成于被动陆缘裂谷构造环境,具有SEDEX型铅锌矿床的地质特征,容矿岩性为一套巨厚的粉砂质、泥质碎屑岩建造,成矿作用与海相基性火山岩有关,矿体产状与地层走向一致,矿石具有明显的纹层状构造,在矿物共生组合上,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。The Hongdun lead-zinc deposit lies in the Kelan Rift Basin.It was formed in the structural environment of the continental rift valley of the passive Aletai land edge in the Siberia plate.It possesses the geologic characteristics of the SEDEX lead zinc deposit.The host rock was silt muddy clastic rock formation whose thickness was huge.The mineralization was related with the base volcano rock.The attitude of the ore body was accorded with the stratum.The ore possesses the obvious laminated bedding structure.There are more zinc bearing minerals than lead bearing minerals in mineral association,and there is no copper-bearing mineral in the ore.The sphalerite is a fewer iron bearing zinc blende,which is formed in the low temperature condition.
