| 摘 要： | 基于滇、黔、桂"金三角"区微细粒型金矿地质特征及地质背景,立足于因果关系的分析方法,以区域地层、构造、岩浆作用、变质作用、岩石地球化学特征、金赋矿层位、容矿岩石、不整合构造、蚀变作用等作为基础,对金矿物质来源、成矿物质迁移、富集条件展开了讨论,类比推理了古风化壳对岩石中的微量成矿元素的初始富集及在成矿中的作用.

| Abstract: | Geological features and regional geological background of micro grain-type gold deposits in "Gold-Triangle" area of Yunnan, Guizhou and Guangxi provinces have been introduced. Based on regional strata and structures, magmatism, metamorphism, lithogeochemistry, host strata and rocks, unconformity surface and wallrock alteration, resource, movement and concentration of gold is discussed. Fossil residua for the initial enrichment of micro-gold and affects during mineralization is analogized. |
