| 摘 要： | 滇西北衙铁金多金属矿床为西南三江富碱斑岩-多金属成矿带中南段典型矿床之一,成矿严格受富碱斑岩及其相关的深大断裂控制,伴随多期富碱斑岩脉体侵入、热液交代与围岩蚀变、矿物质富集及次生富集过程,构成了复杂的斑岩-矽卡岩成矿系统和地表次生成矿系统。文章以万硐山露天采场区大比例尺地质填图为基础,重新厘定和梳理各地质体及其间相互关系,取得了万硐山矿段详细的成矿地质特征及原生矿化的两阶段成矿新认识。

| Abstract: | The Beiya Fe-Au-polymetallic deposit is one of the typical mineral deposits within alkali-rich porphyry polymetallic metallogenic belt in Sanjiang area of the southwest China. Mineralization is strictly controlled by alkali-rich porphyry bodies and the related deep faults and accompanied by multi-stage intrusion of alkali-rich porphyry dykes and hydrothermal metasomatism and wall rock alterations and ore material concentration and secondary concentration of the material constituting a complex porphyry-skarn metallogenic system and a supergene metallogenic system. Based on geological mapping at large scale in Wandongshan ore domain relation between various geological bodies are redefined and recombed and detail metallogenic and geological characteristics and ideal of two stage mineralization are obtained. |
