| 中文摘要: |
| 活龙金矿受韧性剪切带控制。矿区剪切活动明显分为三个阶段,韧性阶段产生面性发育的糜棱岩、糜棱面理,对矿区金的活化、聚集起了一定作用;韧脆性阶段产生缓倾斜网状发育的“鳞片状构造带”,为矿液聚集、沉淀的主要场所;脆性阶段产生三组脆性断层,切割破坏矿体。 |
| 英文摘要: |
| Huolong gold mine,being a small gold mine in Southern Jinlin province is located in northeastern part of North China Platform.Rocks in the mine area are mainly mylonites,which are derived from the metamorphic equivilient of Proterozoic rocks and suggests the existance of ductile shear zones.At least three episode of deformations have been recognized through regional structure analysis.The first episode of deformation is ductile and produces pervasive mylonitic foliation in the Proterozoic gneisses with E-W trend and moderate south vergence.It may have some effects on the gold accumulation and affects the development of subsequent deformation and ore-forming activity.The second episode of deformation is ductile-britle and generates horizontal to gently dipping"scaly structure zones",which cut across the first episode mylonitic foliation S1 and are the main host structures of ore bodies.The third episode of deformation is britle and led to the formation of faults which can be subdivided into three group,e.g.NNW,NWW and NE,and offset ore-bodies in different ways.According to the structure deformation and their controlling effects on gold deposit.we have de fined the ore-forming pattern of Huolong gold mine and several prospecting areas. |
