| 摘 要： | 本文以野外取得的第一手资料为依据，总结了青草坡韧性剪切带的金成矿地质特征。并以剪切带内构造岩常量组分和稀土元素地球化学研究为基础，探讨了剪切作用的地球化学行为。结合对剪切带内含金石英脉的形成时代测定和铅同位素地球化学分析，就应力化学分异作用对金成矿的贡献提出了新认识。

| Abstract: | Based on field investigation data, the authors give a summary on geological characterstics of goldmetallogenesis in the Qingcaopo ductile shear zone. Systematical study of the geochemical features ofPetrochemical composition and REE and lead isotopes of the Wctonites, gold-bearing quartz veins, andwall-rocks in the shear zone has led to a new idea about the role of stress-chemical differentiation in gold mineralization . |
