建议继续开展MVT型铅锌矿床的研究 在爱尔兰。 这些矿床是由共同的金属来源， 下伏变质沉积物和区域热液管道 由大断层系统控制的系统。 进一步的研究目标 地址：（1）化学和同位素特征的 富金属流体;（2）变质沉积物氧化的原因 下伏主要矿床（即，这是否与还原有关 海水硫酸盐？），(3)硫的地理控制 局部富硫流体同位素化学 具体 目的包括：（1）矿物学、流体包裹体和同位素 （2）未改变的Meta分析的背景研究， 沉积物，以评估与矿化有关的蚀变， (3)氧化变质沉积物的详细研究， 蚀变液

Continued research is proposed on MVT-type Zn-Pb ore deposits in Ireland. These deposits are related by common metal sources in underlying metasediments and a regional hydrothermal plumbing system controlled by large fault systems. Further research goals address: (1) the chemistry and isotopic characteristics of the metal-rich fluid, (2) the cause of oxidation of metasediments underlying major ore deposits (i.e. is this related to reduction of sea water sulfate ?), (3) geographic controls on sulfur isotope chemistry in locally-derived sulfur-rich fluids. Specific objectives include: (1) mineralogic, fluid inclusion, and isotope studies of feeder veins, (2) background studies of unaltered meta- sediments to evaluate alteration associated with mineralization, (3) detailed studies of oxidized metasediments to characterize the alteration fluids.
