| 摘 要： | 构造复合现象的研究,不仅有助于解决构造运动时期先后的问题,而且在生产实践中有着重要的实际意义1]。本文以山东夏甸地区Ⅶ—支脉矿体为例,通过区域构造、Ⅶ—支构造断裂特征、闪长玢岩构造特征、矿体构造特征的系统研究,结果表明:Ⅶ—支构造的新老构造体系、同一构造体系复合现象突出,多表现为构造形迹的归并。其中成矿断裂的多期活动、构造性质的多次变化、成矿作用的多次叠加是矿体形成的关键因素;在NEE向Ⅶ—支构造与近SN向脉岩截接部位形成矿体,低级序的NNE、NE、NEE向构造成为主要的容矿构造。

| Abstract: | The study of compounding phenomenon of structures not only helps to solve tectonic movemental sequence,but also has important practical significance in production practice.Taking Xiadian VII-branch orebody as an example,studied regional structure,fracture characteristics of VII-branch structure,structural feature of dioritic porphyrite and structural features of orebody.The result shows that compounding phenomenon of the new,old structural system of VII-branch structure,the same structural system is obvious,which shows the incorporation of the structural features,among which,multiperiodic activities of metallogenic fractures,multiple changes of structural properties,multiple superimposed ore-forming processes are main factors for forming orebody;the orebody is formed in the junction of NEE VII-branch structure and near-SN veinrock,the low order NNE,NEE structures are main host structures. |
