| 摘 要： | 通过对马超营断裂带的几何样式、组成特征及其变形特点等进行研究,识别出马超营断裂带至少经历了韧性逆冲推覆和脆性断裂两期活动,韧性变形早于脆性断裂.其中,脆性断裂与矿床成因具有密切联系.马超营脆性断裂直接控制了金(钼)矿床的产出和矿体形态,含矿热液沿主断层带上升,形成区域性的导矿构造,其中,受主断裂带控制的次级断裂及岩石破...

| Abstract: | Based on the studies of the geometric style,assemblage and deformation characteristics of the Machaoying fault zone,we revealed that the fault has undergone at least two deformation stages:ductile thrusting and brittle faulting.The brittle fracture,which took place later than the ductile deformation,closely related to the ore genesis,gold molybdenum deposits were directly controlled by the brittle fracture of Machaoying fault.The ore veins were mainly hosted in shear zones and extensional structures.The ore... |
