| 中文摘要: |
| 老挝琅勃拉邦省巴乌县帕奔金矿主体处于NE-NNE向大型韧脆性剪切带中。该韧脆性剪切带基本控制了矿区的构造格架,改造和置换了早期构造形迹,使原有的沉积岩层呈NE-NNE向条带状和透镜状展布,并遭受不同程度的韧脆性-脆性变形而具有构造岩的特征。该韧脆性剪切变形带对帕奔金矿床的形成起着空间定位和主体导矿富集作用,它既控制矿带在区域空间的展布,也控制矿体的产状形态;既是导矿构造,又是容矿构造。 |
| 英文摘要: |
| B.Phatem gold deposit in Bak-ou county,Luang Pracang province of Laos is located in a large-sized NE-NNE ductile shear zone,The ductile shear zone controls tectonic framework of the area in which the gold deposit occurs and reworks and transposes the earlier structures.The primitive sedimentary stratum occurs in NE-NNE bands and lens characteristic of tectonite with different ductile-brittle and brittle deformation.Spatially B.Phatem gold deposit is located by the zone by which ore fluid is conducted and ore bodies hosted. |
