摘要
阿尔哈达铅锌矿主要产于泥盆系的NW向断裂破碎带中,矿体具雁行排列、局部交叉产出的特征,以盲矿体为主;成矿早期可能以岩浆热液(399-407℃)为主,而中、晚期的热液以大气降水或混合水(194-287℃)为主;硫分别来源于岩浆热液、沉积地层和大气降水;铅同位素测试结果则显示了成矿(岩)物质的混源特点。矿床为与岩浆热液有关的受断裂控制的中温热液铅锌(银)矿。
Arhada Pb-Zn deposit occurs mainly in cataclastic zone of Devonian System and ore bodies are dominated by blind ones in en echelon and locally cut with each other. Magmatic fluid (399-407℃) dominated the ore-forming stage and meteoric water or mixed fluid (194-287℃) is dominant in middle, late stages. Sulfur was derived from sedimentary strata and meteoric water. Pb isotope composition shows multiple sources of ore materials. It is a magmatic hydrothermal fluid-related and cataclastic fracture-controlled mesothermal Pb-Zn deposit.
