| 摘 要： | 小秦岭成矿带是我国重要的贵金属成矿带之一,金矿受地层、构造和岩浆岩控制,具有＂三位一体＂的成矿模式。太古宙太华群地层为成矿提供了物质基础,区域变质作用使金发生初次富集;早期自北而南的挤压形成规模巨大的推覆构造为含金石英脉的生成提供了有利空间;燕山期构造—岩浆活动对金的活化、迁移、富集起主导作用

| Abstract: | Xiaoqinling metallogenic belt is one of much important best of noble metals in China.The gold deposits are controlled by stratagnaphy,tectonics and magmatic rocks.Its metallogenic progress is complex.Archaean Taihua group strata supplied metallogenic substances,and regional metamorphism progress firstly enriched gold.Compression from north to south formed large thrust nappe structures and they supplied many beneficial spaces for gold-bearing quartz veins.The tectonic and magmatic activity in Yanshan epoch w... |
