新疆阿尔泰南缘红墩铅锌矿床与哈腊苏铅锌矿床对比研究
Contrast between Hongdun and Halasu Lead-Zinc Deposits at the Southern Margin of Altay, Xinjiang
-
摘要: 红墩铅锌矿床与哈腊苏铅锌矿床均产于新疆阿尔泰造山带南缘克兰晚古生代火山-沉积盆地内, 容矿地层为中泥盆统阿勒泰镇组下亚组第二岩性段, 赋矿岩石为纹层状硅质岩及变石英粉砂岩。主要矿体呈似层状、透镜体状顺层产出, 矿石具条纹、条带状、块状构造, 矿体严格受层位和岩相控制, 矿石沉积特征明显, 均表现为锌多铅少, 且闪锌矿为含铁较少的低温闪锌矿, 红墩铅锌矿床不含铜, 而哈腊苏铅锌矿含少量铜, 与矿化有关的围岩蚀变均表现为硅化、褐铁矿化、白云母化、钠长石化、黄铁矿化等。哈腊苏铅锌矿床尚属首次发现, 通过综合对比研究, 表明哈腊苏铅锌矿床可能位于红墩铅锌矿床的东延带上, 与红墩铅锌矿床成因类型相同, 归属于SEDEX型铅锌矿床。Abstract: Both Hongdun and Halasu lead-zinc deposits are located in the Kelan Neopaleozoic volcanic-sedimentary basin at the southern margin of Altay in Xinjiang. Ore-bearing strata are second lithologic member of lower Aletaizhen formation in middle Devonian. Ore-bearing rocks are laminated siliceous rocks and quartzes sandstone. The main ore bodies are stratoid and lenticular, showing striate, banded and massive structure. The ore bodies are strictly controlled by strata and facies. Ores sedimentary characteristics are obvious with more Zn than Pb, and the sphalerite is hypothermal sphalerite with less Fe. The Hongdun lead-zinc deposit contains no Cu, but the Halasu lead-zinc deposit contains a little Cu. The wall rock alteration shows characteristics of silicification, ferritization, muscovitization, albitization and pyritization etc. Halasu lead-zinc deposit is first discovered, and comparative research shows that it may be situated in the east extension belt of the Hongdun lead-zinc deposit, and has the same ore genesis with Hongdun lead-zinc deposit, which is the SEDEX lead-zinc deposit.
