| 摘 要： | 花岗岩及其成矿作用一直是地质学家关注的重要科学问题。本文在回顾花岗岩分类及其成矿专属性研究的基础上，以华南同熔型花岗岩为例，探讨了华南地区与同熔型花岗岩有关的铜铅锌矿床的特点、时空格架及其分布规律，研究了与成矿有关的同熔型花岗岩的特点、源区属性及其与华南古老地壳的关系。本文认为华南地区与同熔型花岗岩有关的铜铅锌成矿作用是壳幔相互作用的结果，且这些同熔型花岗岩具有过渡类型的特征。岩浆源区属性与成矿类型、成矿规模的关系存在着某种制约联系，该类矿床的形成是不同时期华南地区古老地壳改造的结果。

| Abstract: | Granites and related mineralization have been an important scientific issue of economic geologists. In the past a few decades, much progress have been made on the research of granitoid series and related metal commodities. It hosts a huge Mesozoic magmatic province containing abundant W-Sn-Mo-Cu-Pb-Zn mineralization in South China, but the scale of Cu-Pb-Zn deposits is relatively smaller than that of W-Sn deposits. Based on the review on classification and metallogenic specialization of granites, the paper discusses spatial and temporal distribution of Mesozoic syntexis type granite-related Cu-Pb-Zn mineralization in South China, the characteristics of syntexis type granite, magma source, and its relationship to re-melting of the ancient crustal materials. This paper argues that the source magma of syntexis type granite is closely associated with Cu-Pb-Zn mineralization. The size of ore, such as, the scale of copper is associated with the proportions of mantle contribution, but the lead-zinc mineralization is primarily related to the contribution of crustal materials. There is also difference of mantle contributed to the copper mineralization in the different ore-concentrating district. The paper concludes that the Mesozoic syntexis type granite is characteristics of transition type granites between typical porphyry copper deposit-related and W-Sn deposit-related, the Cu-Pb-Zn mineralization was resulted from the re-working of ancient crustal materials, in South China. |
