| 中文摘要: |
| 北干沟金矿床是韧性剪切带含金石英脉型金矿床。韧性剪切带以发育糜棱岩和片理化带为特征,应变强度和退化变质作用从边缘到中心逐渐增强,并形成鞘褶皱;韧性构造岩具有分带性;产于韧性剪切带中心部位的石英脉是主要的含金脉体;韧性剪切带的形态、活动阶段及韧性剪切变质岩的分带性对金矿具有明显的控制作用。 |
| 英文摘要: |
| Bei Gangou gold deposit is a quartz vein type gold deposit in ductile shear zone.The ductile shear zone is characterized by the development of mylonite and schitosity zones.Strain and retrograde metamorphism are gradually strengthened from the borders of the ductile shear zone to the center and sheath fold is developed.The ductile shearing tectonite is zoned.Quartz vein is the main gold-bearing vein occurring in the center of the ductile shear zoning.Morphology, stages of the tectonic activities and zoning of the ductile shearing tectonite control strongly the gold ore. |
