| 为总结湘南矿田钨锡钼、铅锌铜等矿化组合的时空分布和成因机制，并最终为成矿理论在找矿勘查实践中的应用提供参考实例，本文对湘南黄沙坪多金属矿展开矿床地质、地质年代学、岩石地球化学研究，并 将其与湘南其他典型多金属矿田类比分析，认为与铅锌铜、钨锡钼两类矿化成因有关的岩浆-热液活动时 差至少为 5 Ma，不同矿化组合的空间分带受深部岩浆源区多阶段上侵、与成矿有关岩浆的分异程度、成矿 元素的地球化学行为及成矿岩浆-热液体系在近椭圆状穹隆构造等相对封闭的空间等地质要素约束。与 形成两类矿体有关的岩体之 Zr/Hf、Nb/Ta、Rb/Sr等比值及分异指数(DI)、固结指数(SI)等可定量数据能够有效地指示成矿岩体的分异演化程度及其形成各类矿床组合的成矿潜力，并据此判断，湘南地区部分高分异岩体对应的钨锡钼、锂铷铌钽等矿化组合的缺失与成矿期后的岩体顶部经历隆升后被剥蚀有关。 |

| To summarize the spatiotemporal distribution and genetic mechanisms of tungsten, tin, molybde-num, lead, zinc, and copper mineralization in the southern Hunan mining district, and to provide practical refer-ences for applying metallogenic theories in exploration, this study conducts geological, geochronological, and rockgeochemical investigations on the Huangshaping polymetallic deposit in southern Hunan. By comparing it withother typical polymetallic districts in the region, we find that the time gap between magmatic-hydrothermal activi-ties responsible for lead-zinc-copper and tungsten-tin-molybdenum mineralization is at least 5 Ma. The spatial zo-nation of different mineralization associations is controlled by multiple factors including multi-stage upwelling ofdeep magma sources, degree of differentiation of ore-related magmas, geochemical behavior of ore-forming ele-ments, and relatively closed structural environments such as near-elliptical dome structures. Quantitative param-eters such as Zr/Hf, Nb/Ta, Rb/Sr ratios, differentiation index (DI), and solidification index (SI) from intrusive bod-ies associated with these two types of ore deposits effectively indicate the degree of magmatic differentiation and thepotential for forming various orebody combinations. Based on this, we conclude that the absence of tungsten-tin-molybdenum and lithium-rubidium-niobium-tantalum mineralization in some highly differentiated intrusions insouthern Hunan is related to uplift and subsequent erosion of the upper parts of the intrusions after the main miner-alizing period. |
